>There's no need to fucking cast them, they're AR lowers
Do you mean that even full-plastic ones could survive in a fully-assembled gun with otherwise metal parts?

What's the best way to make an Ender 3 ABS ready? I'm not doing anything exotic, just regular old ABS. I've been printing PLA just fine for months now, but I have some parts in mind that need to be more durable and I figure some ABS would do the trick.

Here's the catch, though: it needs to be dimensionally accurate. If I can avoid shrinkydink warpage that'd be great.

My setup right now is a stock Ender 3 with no enclosure or any upgrades. Literally just the printer on my floor.

>>1794395
Not that anon, but yeah. Lowers are good. Lowers are actually good in PLA+, no need for extra fuckery.

>>1794395
>Do you mean that even full-plastic ones could survive in a fully-assembled gun with otherwise metal parts?
You mean like they've been doing for 20 years

>>1794397
I don't know anything about the construction of guns or what internal parts are responsible for what functions, but is there any chance of a PLA lower receiver failing during use in a way that could cause injury?

>>1794399
A plastic lower is fine. A plastic upper is another issue altogether. I wouldn't trust a plastic upper because it's too much friction and heat, in addition to having more recoil impulse.

>>1794402
Yes, but it's minimal. Let me explain first what the lower does in an AR platform.

The AR lower holds the trigger group and mag release(very low impact), accepts a magazine (medium impact), and holds the buffer tube in place (medium impact). It also retains the upper receiver in place.

There are really two ways an AR lower can fail during use, either the upper retaining lugs could fail or the buffer tube hole could break somehow. Both of those could result in serious injury, that being said that hasn't been a very common problem in most printed lowers.

Like any other print, make sure your layers are bonding right and also be sure that your orientation on the bed is right.

>>1794402
>but is there any chance of a PLA lower receiver failing during use in a way that could cause injury?
Lowers don't bear any stress.

>>1794412
Not much. There's a little around the buffer, but that's really the only notable about. Even PLA+ can take it.

Thingiverse doesn't seem to show how many likes/comments/whatever a thing has in the search view anymore, so I can't tell at a glance which options are the most popular.
Is there some option for this now, or did Thingiverse just break it?

>>1794483
Just broke. Probably about time we switched to somewhere else.I like the layout of prusaprinters, but not the way they have their own machines seem so front and centre. They're completely entitled to do that, just annoys me a bit since I don't and won't get a prusa.

>>1794490
>Probably about time we switched to somewhere else
Upload projects to your own neocities page.

Fuck all this zoomer shit.

>>1794495
I tend to upload all my projects to my github, but to get more feedback on things and to improve designs it's (unfortunately) more efficient to use a central service. I've been thinking about hosting my own site from home, but getting a static IP with my isp will cost me even more.

>>1794496
>getting a static IP
Why not just use something like NoIP where you have a local program update your domain name host with your current IP address when it changes?

>>1794496
>I've been thinking about hosting my own site from home, but getting a static IP with my isp will cost me even more.
There are services like dyndns that give you a single domain name for dynamic IP.

>>1794498
>>1794499
Huh, neat. I'll look into it when I have a good chunk of free time.

Does there exist a tool like pic related, but with a flat razor blade on each end, for prying prints off of a bed?
A plain excel chisel blade is fine for most prints, but for particularly stubborn ones it's hard to put sufficient sideways force into it without losing control of the blade once the print finally gives way.

>>1794518
I bet you also have trouble opening square bottles and God forbid pickle jars.

>>1794396
I have a CR -10 and print ABS by throwing a cardboard box over it with the flaps facing outward like doors with a foam flap to keep heat in. It's not perfect but it works great for small prints and is good enough to print questionable firearms.

>>1794502
afraid.org is my ddns of choice

Why the FUCK my printer would retract ~50mm before printing so then it rides around printing fuck all. I've checked everything.

>>1794518
>prying prints off of a bed
Metal blade paint scraper. Use a flat file to sharpen the edge, but also make sure to round off the corners so they can't gouge your build surface. Also have a very small hammer handy.

>>1794382

>>1794422
Even normal place works. All the nogunz here don't know what they're talking about. This one has had a few hundred rounds with no problems.

Thinking of upgrading my ender 3 to a direct drive mount. Thought this was pretty impressive: https://www.youtube.com/watch?v=PnwfLujIF-U
Anyone have experience with a similar setup?

Also, I'm not using the lcd screen at all. Can I use that ribbon as a stepper motor ribbon, or to power a standard dc thing?

>>1794566
What's the purpose of doing this? Is it just pure memery to see if it can be done, or is there any practical reason? These are parts which are presumably widely available, the opposite of what 3D printing is meant for. It's like that guy who spent literal months 3D printing like a thousand little trays/boxes and built a huge cabinet around them to organise all his screws and bearings and wires and shit, when it's almost guaranteed you could buy injection molded one from china which would be near identical but might not match the size he used exactly, and then he'd have just build his cabinet to a different size. Why would you print that kind of stuff?

Unless it's to somehow enable DIY guns without going through legal channels to buy one, but I feel like if you're gonna get illegal weaponry, the black market would probably be cheaper and easier. Especially since you still have to source all the parts that can't be printed, and ammo of course.

>>1794573
In America the part that is seen as the "gun" and therefore registered, tracked, etc. by the law is the lower receiver for an AR-15, all of the other parts can be purchased freely.
As a result of this stupid law using alternative ways of fabricating the lower receiver can make sense.
This same does not apply to most other countries.

>>1794573
The purpose is making fully functional rifles without any way for the government to be aware that the rifle exists. Hypothetically, the state could require all FFLs to submit their sales records for the purpose of rounding up guns, but if you printed your lower it won't exist in any database, manufacturer or retailer. Essentially proving that gun control is a losing game.

>>1794586
>>1794587
Oh, that makes sense, yeah. If everything else can be purchased freely, but this part is controlled, and can be printed easily, then it definitely makes sense (and is definitely easier than going to the black market for one part).

>>1794396
don't know your printer: you'll need enclosure, motor cooling and a build volume heater (so 70°C are good)

I have been meaning to upgrade the part cooling on my i3 machine.
I thought I wanted a 5015 radial fan but I want it to be quiet enough to live with me and my girlfriend in a room.
So I found a 7530 radial fan that pushes 3x more air at the same noise level.
>question:
Couldn't I just turn down the performance to 30%-40% and have a much quieter fan?

Then 30 minutes ago I stumbled upon [pic related] which uses a Delta BFB0712H 7530 12V 0.36A radial fan.
This gave me the idea to mount the fan on any of the sides of the machine or to the inner side of the enclosure (once I get to assembling it).

>>1794641
>30%-40% and have a much quieter fan?
without having it perform worse than a 5015*

Why does this keep happening to me? I've never experienced this before. It might just be this new PLA I am trying. Printing at 190 with fan at 25% for first layer. Bed at 65. Monoprice maker select v2 with the usual mods.

>>1794573
This was just for memery. It cost maybe $15 in plastic, where a real one would be $60+ not including taxes and BG check. Everyone always asks "oh ArE u GonNa priNt GUns?".

Additionally, as someone pointed out, it is to reinforce that gun control in the US is unrealistic and other stuff, but this is not the place for that sort of discussion.

Wait, wtf. Why did I get banned? I posted a picture of a legal, 3D printed firearm. I didn't include political discussion, nor instruction or resources on how to do it. Only theory that it can be done. JANNIES! EXPLANATION PLEASE!

Run your file through Cura and make sure it's not making the printer go fucky. That's really the only thing I can think of, 50mm retraction is way too much to be not a file issue

Apparently it's not that established if people were still asking about it. So, to maintain 3dp topics, and following the rule that material and manufacture discussion, including parts related to the build process and plastics in question, are allowed per the sticky: 3d printed lowers in PLA are suitable >and work fine. Don't leave them in your car though. Look at this picture of just the parts supported and built by a 3d printer in PLA, which has worked and maintained its structural integrity.

>>1794769
>NFA item plans
Just don't print them.

To keep it /diy/, I would like to add that while PLA is okay for this purpose, PLA+ is better and ABS is great. Although ABS is stinky and cancer fume-y and warps and cracks and needs an enclosure and is a little pricier for some filaments.

>>1794778
I've read that ABS is actually worse for this if you haven't mastered it because you will have poor layer adhesion and it will be more likely to come apart.

I'm really interested in printing with ABS though. Would a CR10 require any upgrades besides an enclosure? I've read mixed info about it melting certain parts in the hotend and the Bowden tubes.

>>1794781
ASA is claimed to be more forgiving for not enclosed printers (as well as being a superior material) its also less stinky and toxic but a few percent more expensive and harder to come by.
the bowden starts degrading above >250°C but it should be fine for a bunch of hours. Just cut it back if you start getting issues.

Whats a bigger issue is the Hotend fan shroud. see, the creality one is really shit as 2/3 of the airflow from the fan go down onto the print. This is good for PLA but a nightmare for ABS. You will need a printed one that does not allow this.

>>1794368
Oh jesus my shitty print is in op pic
>bottom right green one
oh fuck I need to stop posting pics.

>>1794783
Would it be possible to print in ABS sans-enclosure with an upgraded/fixed shroud? I heard that was one of the biggest issues with ABS on an Ender 3/CR-10

>>1794787
How is that shitty in any way

>>1794790
ive yet to print abs but ive seen people having success without enclosure at all
closed room, perfect temperature buildplate, eventually turn on the room heating a couple degrees and try it out.
after printing let it cool slowly until you touch/remove it

>>1794720
Make sure the filament is dry, even new filament can be moist out of the bag. Also check the extruder for any debris, clean it up if there is.

>>1794781
You can print ABS with a CR-10. It's pretty close to the edge so make sure your hotend fan is clean and pushing good air flow. You may want to print a few small calibration prints and check your bowden tube to make sure it isn't getting too hot.

This is on sale now for $130. Is it any decent for a entry level printer?

>>1794804
It's fine enough if you're happy with the build volume I guess.

>>1794794
the lines, I posted the pic asking if the gaps are from the extruder being too far or what other possibilities could cause it.

>>1794518
I spray water around the edges of my print, since I use hair spray, and then I hear the print cracking away from the bed, if its still stuck, ill raise whatever part of the print that I can and spray little bit more water. Works pretty well, I only print in PLA, idk how it will be for other prints.

>>1794804
You would be better off to save for a ender 3 pro. Especially if you have a stimulus check coming in.

>>1794720
What is the purpose of having the fan running at all for the first layer?

>>1794778
>PLA+ is better
Is "PLA+" the same material even between different manufacturers? I've been using Sunlu filament branded as PLA+, but I thought it just had their own personal blend of additives to make it better in some way.
Also, what layer orientation would be best, for whatever stresses that kind of part does receive?

>>1794851
I found I get higher fidelity first layers with it. However my issue persists with or without a fan, and unfortunately even with a raft.

>>1794804
>Is it any decent for a entry level printer?
Yes and no. It's the same Malyan clone that a bunch of places rebrand and sell.
All 4 that I had lasted a maximum of 800 hours each before most of the hot end needed to be replaced. The newer models aren't as bad in terms of electronics issues (the ones I had corrupted SD cards if left on for more than a week), but you will find yourself replacing a bunch of parts pretty quickly. The build surface coating they include should quickly be tossed or just covered over with blue tape or PEI.

It's a spring-board printer, but honestly it would be better to save up $70 more and get an Ender 3 kit when they're on sale. Which is all the time.

Wanted to get a Prusa MK3S, it's out of stock and will not resume shipping til June. Where can I find a that will ship sometime and soon is not prohibitively expensive? Like, no more than $750? I was also thinking of the Ender 5 Plus but it also will not ship until May 20/April 20 best. Any suggestions?

>>1794849

Seconding this. I went from a MP Select Mini V2 (almost identical to the i3 mini) to an Ender 3 Pro. Got a regular Ender 3 due to some eBay shenanigans, not really much practical difference, by the way.

I don't even use the Mini any more. It's inferior in every way to the Enders. For the price difference, I really don't think either the MP Mini or the i3 Mini are worth it.

>>1794925
Can't answer your question, but honestly, you probably picked one of the worst times to get into this. If I were you I'd bite the bullet if you actually have the desire and money for a Prusa and wait it out - it's probably only going to get worse, what with the 3D printing PPE craze that's going on. It's even worse than fidget spinners because people can convince themselves "I'm doing this for a good cause!" or something. I wouldn't be surprised if less-reputable manufacturers started price-gouging, if they haven't already.

>>1794925
Oof. My Ender 3 DIY kit just shipped a day or two ago.

>>1794854
>same material
Not even close. That's kinda the case with all filaments, but PLA+ is a vague term. I use Overture PLA Pro, which is basically a fancy PLA+. It's relatively inexpensive, prints beautifully, and is pretty tough for a PLA derivative. Also, you're dead on about companies having different formulations. Overture is almost certainly a different formulation than Sunlu or eSun.
>layer orientation
For a lower? Most people print them upright, or at least that's what all the .gcode and .stl files have them as. That makes sure the threads on the buffer tube don't sag out.

Hey guys, I'm having an issue with my ender 3 where the plastic adheres to the bed really really well and is basically impossible to get off without scratching the bed surface. Any advice on how to reduce my build adhesion? Turning my temp down? All default setting from the cura ender 3 profile--200c hot end and 50c bed temp.

>>1794941
More is better with bed adhesion. Grab the paint scraper that came with your kit and file down one edge. The edge is really squared off out of the box, and it doesn't do much for you. Once you file it, you'll be able to maneuver it underneath the print. File the corners a little if you're worried about scratching it up.

>>1794396
Not a direct answer, but consider using PETG instead. You'll get a lot of the advantages of ABS without needing to enclose

>>1794957
I already have ABS, it's a long story but I got some as a gift and I just don't want to waste it.

I've looked into PETG a little, it seems kinda finicky but not nearly as much as ABS. I guess the bigger question here is if a stock Ender 3 can use it.

>>1794958
>>1794958
PETG is a little stringy compared to PLA, but it prints nice structural parts with a little dialing in.

I've printed PETG on a stock ender before, but you might want to pick up some higher temp bowden tubing just to be safe. I think you can get some for under 10 bucks from th3d.

>>1794958
Yes, but not to its full potential due to it wanting to be printed around 240 which breaks down the ptfe tube. An all metal hotend fixes that though.

>>1794941
The default scraper is shit. I recommend pic related, at least for getting under the edges.
The default bed is somewhat flexible, isn't it? You could take it off the metal surface and flex it to pop the print off. If you're using the glass bed, I don't think you have to worry so much about scratching the finish. Most of the "scratches" I make on mine end up disappearing anyway when I wash it.
If you want an easier time getting underneath the lip of the print, you could print with a small brim that lifts up fairly easily, and gives you a straight plane to the underside of the actual print.

>>1794964
Not that anon, but I found the default scraper works fine if the edge is filed down just a little. Aside from the squared edge there's not really anything wrong with it.

>240 is apparently too much for the ender 3 tube
>I've been printing all my sunlu pla+ at 230, and I do have some petg on order, haven't noticed any problems yet
Hm. Should I bother trying to upgrade if I haven't noticed any issues yet? If I do, what are the advantages and disadvantages of an all metal hotend compared to just a better tube?

Oh and while we're talking about upgrading an ender, is an all metal extruder really important or just "nice to have"? I see it mentioned often but you see so much garbage mentioned often (like the creality motherboard replacement which is overpriced and underpowered) that I'm still not sure whether it's a meme or genuinely worth it.

>>1794854
I find the sunlu pla+ to be really smelly. Especially the black one. Only recently noticed that I even see visible but subtle smoke is coming from the nozzle when printing without a fan. Smell is not as bad as abs but really noticeble

Looking at videos of the elegoo mars before I buy one.
Pic related is a tear down video and I noticed something interdasting if anyone can confirm it.
It looks like the bit I've arrowed is a UV COB attached to some kind of relfector/refractor.
Is that the case?
If so do you reckon it would be possible to swap it for a more powerful COB in order to shorten cure time?

>>1795084

Whoa BTFO'd

>>1795109

Not a mars owner, but the inside of my Photon looks the same. It's a 4-sided reflector "cone" and there is a heatsinked PCB with UV LEDS on the bottom where you've put the arrow.

Technically you can swap it, though i'm not quite sure how much the motherboard's mosfet can handle. The newer generation of cheap SLAs tout their use of an evenly distributed led array instead of this cone thing as a selling point, so perhaps uniformity matters more than power output.

>>1795122
So in the newer machines is it like a platform of LEDs as opposed to one central point?

>>1795126
>So in the newer machines is it like a platform of LEDs as opposed to one central point?
That's what COB LEDs are.
An array of leds directly on a pcb with phosphor over all of them.

>>1795126
>>1795128

They're both technically COB LEDs, it's just that one has a pcb with 4 of them (with 4 sub-leds each) while the other has an array of 28 less powerful ones with lenses ontop

>>1795130

Pic of the whole photon S unit

>>1795131

And just the pcb without the lenses

>>1795132
Pretty neat.
It'd take a while but I imagine you could solder better LEDs in their place, like you say the mainboard would have to be able to drive them.
All my experience comes from grow lights so I might be wrong here but generally speaking no-name chinese LEDs are usually rated at a certain wattage then underdriven.

>>1794843
OC is OC

>>1795216
The indicated range is 190-230. I just thought hotter is better, since it'll flow easier, and for some reason I thought it'd also make the part stronger - which is apparently supported by empirical evidence according to the other anon's post.
Is there any reason to try to go low? I never really experimented, just cranked it to high, had no issues, and never changed what wasn't broken.

>>1795221
>and for some reason I thought it'd also make the part stronger - which is apparently supported by empirical evidence according to the other anon's post.
It will increase layer adhesion because the higher temps allow the extruded filament to melt more to the lower layer.

>>1795206
I'd say even 4.3 was fine, that was what i upgraded from, the only thing that's nice is that cura now adds a nozzle wipe before every print

Is Slic3r better than Cura then? It's one of those things where I picked one thing and stuck with it forever.

>>1795219
Thanks anon, good shit. Still learning about this, but all the PLA I've used said to print 190-210
>>1795221
No, I'm just kind of a wuss when it comes to heating plastic.

>>1795230
Sunlu PLA says 190-220, but their PLA+ goes up to 230. As has been established earlier in the thread, PLA+ is manufacturer-specific, so it'll be different for other brands.

>>1795221
>Is there any reason to try to go low?
if you dont care about optic, surface finish and dimensional accuracy, no
>>1795219
>optimal layer adhesion
only if you use his exact slicer and machine settings.
melt zone temperature is not heater temperature and there can be a bretty high delta depending on how much volumetric flow you push through. And volumetric flow depends on every fucking slicer setting there is.
Just typing in 230° will give me totally different result than you or him.
He is a hack as he looks over those things isolated. In 3d printing extrusion each variable has large influence on all others.
>you dont know wtf youre talking about
im printing my very first benchy right now (never wanted to but im bored) will post later

>>1795237
Melt zone temperature will at most differ by a few degrees from the one measured at the temperature sensor, anon we're talking about a big bad block of metal, with high heat conductivity, two measurement points a few mm apart will have around the same temperature.

>>1795215
Ah, you are correct. I didn't know about it until a few years later.

>>1795254
>big bad block of metal, with high heat conductivity,
"melt zone" is the molten plastic mass in the nozzle between ptfe liner and orphus, where you keep pushing coolant (fresh pla) constantly through

By your logic, one would not need to raise temperature by going from a .4mm to 1mm nozzle with 4x the layer height, as the whole chunk has reached temperature equilibrium anyway.
And the Volcano style would be worthless snakeoil

>>1795120
Most users will be fine with 8bit 16MHz processors and if you need 32bit because your use case is advanced enough, you are likely to be able to replace the motherboard with an aftermarket one perhaps even bundled with your desired stepper drivers.

yes but the atmega is akshually a lot more expensive than the stm32s commonly used in print boards (thats why older melzi boards stuck to even crappier 1248u's)

then on the bottom half of the pic shows the gaps in between the lines showing up, so IDK what I did wrong, maybe wrong filament %? I was at 20% I believe, I went back on thingiverse, and the designer said 50% recommended.

>>1795445
Amazon or Matterhackers, probably

>>1795445
I ordered some PLA from Amazon recently and despite the initial order saying it'd take 2+ weeks to be delivered, it ended up showing up after only a couple of days.
If you can find TPU on Amazon with Prime Shipping, you may be able to get it pretty quickly even if they initially say it'll take a long time. The displayed shipping time might be a worst-case scenario or something, I don't know.

>>1795477
Infill shouldn't affect the density of the top surface as long as you've got 2 or 3 top layers.
Do all your prints have this problem?

>only 22 out of 30 prusas worked
oof, shoulda just bought 150 ender 3s or something

>>1795488
It varies from different prints I've done but its noticeable.

>>1795513
Have you calibrated your E-steps on the printer yet, or otherwise verified that you're not underextruding?
Alternatively, slicers have various options that can help with this problem such as adding top surface skin layers that have increased flow rate, or adding more top layers so that there's less sag into the infill.

Imagine believing:
>Pla needs a heated bed
>Petg can't be printed at pla temps

More or less true. Can be neat to try a different plastic.

The frame is still the same, the part cooler is the same, still 4 bed screws with shit springs
the fan grill looks horrific restricting

its like they went on thingyverse and integrated the 10 most popular ender 3 accessories
They had the chance to make something great and fix big issues on the frame, but unfortunate they insist on making a product with gaping issues

my points still stand. I have a dialed in ender myself, if i criticize the construction of the shitter its purely out of experience

>>1795683
meh, go back a few years and 3D printers were $1000s, they probably just low balled it when the ender 3 came out a $150 and now are feature creeping their way back up

Overall print quality has improved too. Getting some oozing now that I didn't have before for some reason, but I'm working through it.

>>1795717
Redpill me on th3d, I've seen it mentioned a couple of times but I can't figure out what the fuck it really is
What does it have over "standard" marlin?

>ender v2 video on yt by creality
>belts are loose
I know it's just promotional but fuck that annoys me

>>1795717
>>1795720
Woops, apparently th3d is still 1.1.9. Anyway what it is is a customised version of marlin, and makes it super simple to install new marlin releases.

>>1795727
So does it just come with an updater or whatever, or does it bring anything else?

>>1795729
It has inbuilt support for the products th3d sells, but basically you go into a single file and select which printer you have, and change a single line. If you have ABL stuff there's a bit more to do as well, but I don't so I haven't looked that far into the guide. After changing that line save it, then compile and upload to your printer and its done.

Are these actually any good, or just a meme that went too far?

>>1795749
Depends on your ROI. If you're printing super abrasive stuff and keep having to change your nozzles, then this might pay itself off pretty quickly (not just in nozzle cost, but also in time spent replacing nozzles, plus time spent regularly checking whether the nozzle needs to be replaced).
If you're printing PLA then it's definitely not the tool for you. Or if you want to print abrasive shit every now and then, a steel nozzle is probably more economical.

Unless you've got a ton of disposable income and want to make sure for a fact you will never have to worry about replacing your nozzle.

>>1795749
PRetty fucking good but what >>1795752 says, unless you are printing a spool of carbon every week it's probably not even close to worth it.

first benchy
should have done another perimeter and 15° cooler but then the stringing gets out of hand

>>1795631
Without watching the video, I'm assuming he bought the kit version. It's no that they're terrible, but they require a lot more assembly that say a creality printer.

>>1795723
Why put a fan cover on there that's just going to restrict airflow?

First print failed. First owl missing head, second also fell over and is lobotomised.
Adjusted bed and successfully printed a comb. Trying to print my own 3D model I made earlier.

>>1795982
Second and Third prints were successful. This third one is a model I made myself in Blender and printed.
This is so cool. The printer only cost me £120 and I even got the free spool with it which it said it wouldn't do so I think they just sent me a new unit.

So I got a Velleman K8200 (3Drag) printer that I got back in 2015, haven't used in 3 years or so. The rails got a bit rusty sitting in the garage but I cleaned it up and am trying to get it working again.
Is it worth sticking with this printer and doing some upgrades or getting an ender 3 pro and ditching this one?

i broke my original keycap fucking with the stem again so i printed another, slowed down with painting, and just finished the face with sanding and cleanup

Does anyone know of a good airtight tupperware for a single filament spool? I've been looking for something like cereal tupperware, but few shops post precise dimensions. Already ordered the snapware cereal one and it fits some spools but not the larger ones.

>>1795874
How is that possible. That looks incredible. I can't see any layer lines

i was finding it harder to pull filament on my ender 3 when changing it and tonight it snapped right after the extruder motor and bowden tube. when i freed the tube finally it was burnt. how common of an issue is this?

>>1796151
ptfe tubes have a tendency to burn and melt over time, even if you're holding temps around 200. They're a consumable, more or less.

>>1796148

They're using that sparkly type of filament that tricks the eye into not noticing them. If you spray that with primer the layer lines are going to become very prominent

How tight are the tolerances with sla printing?
Like if I were to design a mortice and tenon in cad would I be able to just print it and get a near perfect fit or would I need to design it with some play?

>>1796173
roll is already half empty. will switch to red after

>>1796184
You need to design it with some play. 0.1mm is enough in most cases, although sometimes, depending on the accuracy and infill, on an FDM printer you can get away with an interference fit.

Does anyone know what is this? I have an ender 3 I already checked the z rod and it's fine and I can move everything up and down with ease. Temps 200°C and fan at 80% this lines are only noticeable at some angle, I also changed the hotend .

>>1796227
I can't quite tell from that image, but does it seem like it has ripples like >>1794047 ?

>>1795874
Stringing and overhead issues seem to be your biggest problems. I can also see the infill lines on the benchy's hull. Unfortunately with the sparkly filament and really dark photo there's not much else to say.

I've tried everything, I have ABL, I did a cold pull, I've cleaned the extruder, tuned the extruder, but one day it went from a good XYZ cube to complete shit that crumbles in your hand.

>>1796277
I'm not sure what steps you may have missed, but 3 things:
1.Try different filament.
2.Reflash current firmware/upgrade your firmware. See if TH3D supports your printer.
3.Are your temperatures swinging/thermistor badly calibrated? Try upping temp by 15 degrees and see what happens.

>>1796279
My thermistor is fine and consistent in octoprint, I upgraded my firmware recently due to installing ABL (the XYZ cube on the left was printed on that firmware), and the filament worked fine for me a few days ago and now it's giving off shit tier prints. I'll try a different roll when I get one soon, but I don't think it is any of those.

What program would you recommend for making 3D models? I'm looking to make molds for silicone and epoxy keychains and accessories. I'm gonna send the files off to have them printed.

Extruder gear is rotating offset from its center axis, creating a sine wave pattern in extruder speed. Cause: center hole of extruder gear is too large, when set screw is tightened down to motor, it pushes the gear offset from the motor shaft center axis. Solution: Get a not shit extruder gear that fits with good tolerances to the motor shaft.

Why aren't you guys 3D printing PPE to donate to hospitals yet?

>>1796392
I have already donated 300 Subea adapters a few weeks ago, they're in use at my local hospital. Those 3DVerkstan faceshields were not approved, however, so I'm not printing any faceshields right now. Hospital has my number though, if they need new stuff they know who to call - I've got seven UM2's on standby for them.

>>1796319
In my experience, solid edge is much less known. Not sure why... seems like a good program and it's what I learned in highschool, so I've stuck with it, but I've gone to three separate job interviews where people have never heard of solid edge. (Not a mech engineer, so it doesn't really matter)

WTF is this printer? XY motion but a bed-flinger and the kinematics of a delta combined. What would the point be?

>>1796416
Less computing power than a delta, allows for a pretty long bed, showing off.

>>1796309
I haven't done anything to my hotend recently.

>>1796416
I know nothing of that printer but just going by the gif:
It has the same advantage that a delta has where no axis has to carry another axis but it looks like it could handle more force than a typical delta and also doesn't need a circular build plate.

>>1796392
I've printed 50 of those adjustable surgical mask straps for one of my parents' nurse friends and her coworkers. I can fit a bunch on a single plate, so it only took about a day.
I'm not altruistic enough to do any serious production for donations, though.

What can I do to fix inconsistent extrusion? I'm talking very slight layer variations that are visibly under certain angles and aren't Z related. PID hotend again? Do a million passes instead of 8? Replace entire extruder assembly with a Hemera? I want this shit gone. Printer is a Sidewinder X1 btw.

>>1795037
I've heard some PLA+ is a PLA/ABS blend

>>1796629
Sounds like the extruder gear is sitting off-axis on the motor shaft. Replace or center it.

After a night of drinking heavily I awoke to find a comformation email for a ender 3 pro and a 2.2lb spool of PLA 1.75 fillament. Can someone point me in the direction for babbys first 3d printing?

>>1796643
Cancel the order and order a Prusa instead.

>>1796643
What's your questions? It's reasonably straightforward and unless you have the printer in your hands it's kind of difficult to help out right now. Are you interested in the modeling aspect, or how to get good quality, or what? Generally most problems are either something you can solve yourself quickly, or something that's easily google-able.

I got tired of touchui being absolute trash, so tried out the two alternates I found today. The first is OctoDash. Findings on this were that it is almost worthwhile, but UI is not responsive enough for me, and I did not like how it navigated at all. The one thing I did like was the temperature adjustment navigation.

>>1796643
Even though some filaments can be rated food-grade, deposition printing by its nature isn't going to produce a non-porous product so the fantasy buttplugs you're planning to make probably shouldn't be considered body-safe

I should also say that Octodash had not the best install experience. I'm running on an orange pi lite, not a standard raspberry pi, so I had a few more hoops to jump through to get it working.

Not happy with that, I tried OctoScreen. The install for octoscreen at first was really really easy, just a simple dpkg command, and everything was set to go. I tested it out and found some things that I would want to change, so I did end up downloading the source and modifying the menu navigation as its available package has things like toolchanger and multiple extruder nozzles to deal with that I don't need. After building with docker and following the same install procedure as I had previously done with the precompiled package, I was pleased to see my modifications--removal of unneeded panels, and adding a 100mm step to the jog commands. I really think the menu should be more configurable by the end user, but oh well. This isn't running in a browser, it's a native xorg application and as such is very snappy and responsive. I am very satisfied with this, and will keep it as my interface for the touchscreen on the printer for the foreseeable future.

I want to make my own filament out of PETE plastic bottles. I know I will need to add plasticizers and additives to lower the melting point and crystallinity of the plastic. Does anyone know what I need to add?

>>1796813
love

>>1796798
What if you coat them in food-safe epoxy or a similar liquid that cures into a hard smooth surface?

>>1796822
It would work, but you might be better off printing a mold and casting it out of silicone unless you want to be as hard as... well, plastic.

>>1796849
Aren't most buttplugs typically completely rigid? I'm pretty sure I've seen ones that were, or at least looked like, smooth metal for instance.

>>1796849
Jokes aside I am wondering about the feasibility of casting 3D printed mechanisms inside silicone things to put in my butt.
I haven't been able to find much about how PLA or ABS bond or otherwise interact with platinum silicone though, anyone seen anything on that?

>>1796850
Yeah, but I was speaking from a general perspective, since I know this is a popular but still taboo subject. I don't do these things myself but I might as well apply what I do know and stop some poor anon from lacerating their insides or getting pieces of plastic stuck inside them.

>>1796853
Feasible. You can cast molds no problem - oomoo 30 is maybe not skin-safe but it's cheap ($25 for I think 2 pints) and a great starter to learn how to mix and pour. Other products made by the company are skin-safe, but they are clear so it's harder to tell if they're mixed proper if you've never worked with them before. There's also different hardnesses of the silicones if you want to mess around with that.

>how does it bond
Not really well, which is good. It sticks a little bit, but I think that's mostly due to it filling in the cracks and gripping those, in my experience. It's pretty easy to peel off, particularly if you've got larger details. Silicone caulk binds like a motherfucker, though, since it's meant to be an adhesive, so don't use those unless you have plenty of release agent.

>>1796857
>>1796853
Smoothon Dragonskin is skin-safe.
It releases from everything easily, so you must have features on your print to keep hold of the silicone, like little holes or perforated walls.

Silicon caulk is a good adhesive but its difficult to mould because its almost like a paste. Also im sure its not skin-safe, but i have not yet developed butt cancer yet...
You have to make sure after curing all the vinegary stuff is gone from it, keeping it in water for a week, replacing it every day could help, sometimes hot water. But keep it below the softening temp of your 3dp parts.

Id go for dragonskin.

>>1796857
>It's pretty easy to peel off, particularly if you've got larger details.
Oh shit, that's groovy. I've been wondering about the possibility of using smoothed ABS as moulds directly, in addition to internal PLA mechanisms/armatures.

But it'd also be useful in a different way if it bonded.

>>1796866
I have a bunch of Smooth-On already, two different Dragon Skins and a soft Ecoflex.

>>1796867
>>1796853
I have to say I'm a little concerned by what you mean when you say "mechanisms", frankly
>Dragon Skin and Ecoflex
That's the stuff, yep.

In theory, what's the easiest way to make non-layered molds? Does "print -> slather in a layer of epoxy and make sure it's smooth -> cast" sound like a decent idea, or is there a generally used better way?

Finally fixed my god awful layers and tried a lithograph.

>>1796884
That's about right.

Linear rails or rolling on extruded aluminium? What does /3DPG/ think?

V slots and rollers are fine for most people, linear rails give mechanical engineers a stiffy while making sure you have maintain an appropriate distance from the V-slot plebeians.

>>1796899
By the way, I'm assuming that would also make PLA food-safe (assuming the epoxy was food-safe)?

Haha, you got me. Or did you? Two smooth rods = one linear rail?
>>1796913
Why is it wrong?

>>1796937
>Why is it wrong?
on such assembly's you want a big locating bearing and a small floating bearing on the slide.
this does only somewhat work because lmu's tolerate a little axis misalignment, if it gets too extreme or with slide bearings you get binding issues and visible artifacts in the print.

nearly all diy core XY designs utilize a floating bearing. gets to show how western anons doing this in their off time have a bigger understanding of mechanics than paid chink engineers

Thank you very much.

it is still a misconstruction

I have some clear resin and white resin. When I try printing with the clear resin I get half cured resin on surfaces messing up the dimensional accuracy I need. (threaded part). But when I print with the white resin its too brittle.
I was thinking of tilting the model some more to see if that helps with the clear resin print but was wondering if this was a common issue like normal exposure was too long or something.

>>1796971
nice

>>1796984
Different resins have different exposure times, yeah. Here's a link to a bunch of brands and types people have tried, maybe you'll find yours there:

>>1796937
>Two smooth rods = one linear rail?
No. Needs to be able to be mounted on a flat surface to be considered a rail.
Usually people mean pic related with linear rail.

>>1796976
Standard i3 usually has one long lm8luu or two lm8uus on one of the x-axis rods

Resin printer guys, what magnetic stirrer do you use for cleaning?

>>1797153
An old soup takeout container from my local ramen place and my hands works well enough for me, no magnets needed.

That, or the Form Wash.

>>1796904
Rods are more accurate, aluminum extrusion manufacturing isn't designed for precision.

>>1797158
>That, or the Form Wash.
I'm too poor for that

>>1797120
Yeah I used that as a guide for picking values. Its just the clear resin Im getting issues with accuracy on. My instinct tells me than its due to the clear cured resin letting light go to uncured resin on top.

>>1797179
>clear cured resin letting light go to uncured resin
Likely. Some people call it "fuzzing", some people call it "bleeding", but clear/translucent resins sometimes suffer from loss of detail due to light overpenetration.

>>1794402
PLA is undesirable due to its poor water resistance. AR-15 lowers don't get stressed much compared to the upper or the bolt/star chamber itself. You can build lowers out of wood and they work fine.

Is it a bad idea to jump into MSLA if I've never done 3D printing before? I want to do multiple high-detail parts at a time so I feel like MSLA is definitely what I want to be using

>>1797224
Nope, go for it. Isopropyl is probably in short supply, but get some gloves and a bunch of newspaper to put under your printer until you're comfortable with not dripping all over the surface.

Extruder keeps jamming when im printing wood filled pla, any way i can avoid this? Will a higher temp help? Printing at 200 degrees

>>1797215
>water resistance
What does this matter? I wouldn't really plan on getting it wet.
Or do you mean the moisture it absorbs from the air could weaken it over time, or something?

>>1797215
>PLA is undesirable due to its poor water resistance
the fuck are you talking about?

I got a photon at the beginning of the year. FDM printing didnt really carry over. But I will say trial and error is a lot easier on the fdm printer.

90% guess that a gap formed between the PTFE tube and the nozzle over time.
Get a new nozzle and refit the PTFE tube
(remove the PTFE tube, heat the hotend up, remove old nozzle, tighten new nozzle and tube connection, then release both a quarter turn, press the PTFE tube in completely, retighten the nozzle and tube connection so its a tight press fit between the nozzle and the bowden)

it also does not hurt to change the PTFE tube if its old.

>tuned the extruder
never do that, you can fuck up everything. Just tweak the flow/extrusion rate in your slicer profiles if you under/overextrude. Has the same effect and you don't mess up the firmware of the printer.

Anon, how big is this

Hueland lurker here.
Was thinking of getting a Tarantula pro since our economy is going to shit and its the last moment before prices get readjusted to the new low our money has fallen into.

I picked the tarantula versus the ender 3 since both are going for the same price here and I like the Tarantula's board and extruder more even though it's volcano hotend cant use 0.2 nozzles, and I dont mind building it from scratch. Also was thinjing of getting a bltouch for lazyness, and a second Z axis with the thing so I already assemble it all at once.

Am I making a mistake or should I do it?

>>1797443
sovol sv01. its what the ender 3 pro should have been.

>>1796904
Extruded aluminum rollers a shit. I hope you like to breathe aluminum dust. The surface will break down fast and and they can not be properly serviced. Manufacturers do it for $$$, so dimwits buy replacement rollers when their printer invariably degrades.

>>1797482
>aluminum extrusion breaking down faster than rubber wheels
Anon, what kind of insanely abrasive rollers do you have on your frame that destroy it before they themselves wear down?

>>1797443
The Tarantula does not have a flex bed which I like so much on my Ender 3. I have the nonmagnetic one on the glass fiber carrier. I havent seen this anywhere to buy. You might be able to make your own (stick the build tak sheet on some glass fiber cutout) The magnetic one is shit, don't buy it.
Aside from that, it doesn not really matter which printer to take.

>bltouch
not worth it imho. Just eyeball it. A levelled bed lasts, it does not need to be readjusted for every print.

>second Z axis
also not worth the hassle. just adjust your v-roller excentric nuts properly, it'll be alright. second z makes more sense on bigger printers like the cr-10

>>1797482
>I hope you like to breathe aluminum dust.
what the fuck are you talking about

>The surface will break down fast
wrong. I've went through so many spools and the vrollers haven't even chruned through the anodized coating of the aluminum yet.
What does wear are the rollers.

But vrollers are shit I'll give you that. But they are also cheap and better for low budget printers.

>>1797482
I rather have rollers and a proper leadscrew than a proper linear guide and belts.

rate my bicycle smartphone mount I just finished

>>1797512
If you could have leadscrews and linear guides?

>>1797533

>>1797533
nice. The green part is elasic and printed flat I assume.

For the bed I was going to get a small glass square and hairspray it, I heard the flexible bed lasts too short to be worth it, even just gently folding it and not scraping like a regular bed.

>>1797452
Will look into it

>>1797508
What even is the point of a flex bed? Do people really have that much trouble taking their prints off it?

>>1797563
>I heard the flexible bed lasts too short to be worth it, even just gently folding
This isn't true at all.
I've used my ender 3 flex bed for 1.5 years and I don't know how many spools now.
The bed is almost like new.

There have beed idiots sanding their bed, that would of course kill it. And yes, if you would fold it 180° it would break.

You might have read about the magnetic bed instead, which is indeed shit.

>>1797566
It's just a lot simpler. Works great with TPU, PETG, PLA.

>>1797568
Thats good to know, really wouldnt know the magnetic and non magnetic beds differed much.


>>1797452
The SV01 looks to have good specs, a not as modular board as the tarantula but overall better structure and power supply. But I was thinking of later switching to tmc2100s or tmc2208s for the silent factor and a non modular board makes that more expensive.
Also they say they have stock here in the BR land but they dont convert to our coin on the site so I know their conversion rate, I gotta look further and contact them.

so what do you guys do with your printers?

>>1797573
>But I was thinking of later switching to tmc2100s or tmc2208s for the silent factor and a non modular board makes that more expensive.
You'd still be stuck with a shitty 8-bit board

>>1797575
read the thread

>>1797577
Sadly yes, even tho I dont plan on doing over complex stuff so I dont think itll be a prob, and the Sovol's Atmega2560 is also 8-bits.

>>1797573
isn't an skr like 20 bucks though
sounds cheaper than upgrading to 2nd z or direct drive and all that jazz

>>1797577
Searching about those boards it seems the SV01 just separates the main board and the Ramps board rather than being built-in like the Tarantula's GenL, so my fears of incompatibility of further upgrades is unfounded, and now it seems a much more interesting choice.

Being somewat pre assembled sounds like a plus too, but what got me is the big case for all eletronics underneath.

Well, its time I do my part and contact them, thanks for the help.

>>1797575

>>1797593
Hueland lurker here again
After going to their website and trying to checkout a printer from Brasil to my addres in the same country the price of the Sovol skyrockets to 500 dollars, that is 90 dollar shipping for internal travel wich makes no sense, considering I live on the same state as the depot.

Also, the sovol only offers built in motor drives as a silent upgrade with IMO is a scum move.

Overall a great bait product but with red flags all over it.

There was a reason I was looking to buy from a non chinese store, even with our crazy taxes its cheaper than the price the exclusive Sovol shop wants to charge.

TL,DR thanks for the help, I'll go with the modded Tarantula.

>A levelled bed lasts, it does not need to be readjusted for every print.
But if one's prints tend to grip the bed tightly, can't the process of removing the print jostle the bed and mess with the leveling?

>>1797672
I mean maybe, eventually, but I haven't leveled my bed in like two spools and it's fine.

>>1797666
The frame is definitely a weak point.
A cheap mod is to brace it with threaded rods.

There are also people going all out and replace the frame with a laser cut steel frame.
Or rebuilding the whole thing into a CoreXY printer using aluminium extrusions.
But you could buy multiple Ender 3s at that point.

Is PLA and PETG good enough for gun parts? I'm from Yurop and I'd like to print and assemble something because I have way too much time at work during this virus thing.
Is it even possible to make something from 99% plastic in Yurop? I asked this on /k/ and they directed me here.

>>1797697
If you don't know if certain polymers are good enough for gun parts, you shouldn't be making gun parts. /diy/ has a no weapons-policy, and you shouldn't be making your own guns in Yurop - depending on the country it can be extremely illegal.

Wrong. You can discuss materials and build processes.

PLA is good enough for receivers. PETG is Better. There are trigger packs made of plastic, but they suck. Barrels are made of nylon and only handle a few rounds of 22. You'd need some metal parts for a good barrel. Look up the fGC-9 for a fun that can be made from 100% non-regulated parts.

Ended up buying an ender 3 pro and a cr-10 max.

What software should I be using for CAD + Slicing (is there any other software I need)

>>1797734
slic3r

>>1797737
This is an all in one type of software?

Thank you for the help!

>>1797739
no it's a slicer
I can't give good recs for cad so I just recced a slicer

I guess I can tell you the usual recommendations of blender for modelling, fusion 360 for ultrabotnet cloud based but easy to use, and I dunno solidworks or something as "real" cad

>>1797741
Usual recommendations are great. Thank you for that, I have no idea what I’m doing yet so that is perfect. Thank you!

>>1797734
why did you buy two

>>1797734
Wtf why would you buy two shitty chink printers?

>>1797734
>CAD
Probably Fusion 360 unless you want to pirate something
>Slicing
PrusaSlicer
>any other software
Windows 10 should have a built-in STL model viewer but Blender helps if you want to inspect it closer or edit STLs

>>1797708
where to get lwds

>>1797756
this

>>1797745
What should I have bought instead? I wanted the max due to the big print size and the ender as a backup.

>>1797744
Waiting for the Max to ship and going to pick up the ender locally. Going to use the ender as a back up

>>1797747
If I did pirate, what would be a good starter prog? Or should I stick with fusion 360

>>1797781
not him but its generally a good idea to start small
the ender is my second printer. Ive bought it for 180€ i believe and had it for a year, diagnosed a lot of chinkery and am comfortable doing nice prints with it >>1795874
beside the warped bed im now satisfied with it.
But speaking for me, due to my personal experience with the machine i will never buy creality again. Chink shit they put on a "premium" pricetag thats not justified. And each and every of their machines uses the same components, thus has the same chinkery

>>1797789
Inventor or Solidworks are the go-to's, but there's really no reason to jump through hoops and get those working if you're just starting to learn CAD; the "professional" programs only really start differentiating themselves once you get into the advanced features (simulations, analysis, etc.), usually.

>>1795477
what printer/slicer are you using? your prints look perfectly usable and strong. i have the same kind of visible lines if i use the standard quality setting in cura(pic related). For the first layer i have raised the temps 10C, and use 105% flow now. theres a test block out there some where to fine tune your extrusion rate. I found that raising the temp and flow rate help my prints. i use and ender 3 pro, and cura. The bottom of my first layer comes off the bed with the texture of the bed now, no lines.

>>1797789
fusion is really good, but the controls are bound stupidly, switching back and forth between drawing in fusion and modeling in any program makes my mouse hand cringe

>>1797836
>The controls are bound stupidly
Like what? Seems pretty similar to most I've used, apart from the different hotkeys every program is bound to have

>"bound" to have
haha

>>1797734
I use Cura for slicing, personally. Not sure how it stacks up against other available slicers, though.

>>1796376

Ok chang

I'm an idiot, so bear with me for a second. Build plate on my fresh OOB Ender wobbles slightly. What do I tighten?

>>1797697
There are whole communities built around designing for this problem but afaik it's an ongoing challenge. I'm not an expert on this at all and haven't looked into the designs at all beyond listening to some interviews so don't believe me, but:

>Is PLA and PETG good enough for gun parts?
For *parts* yes. There are some very functional projects which can put together a fairly reliable gun out of mostly prints, but they rely on real kit parts for metal components like presumably a barrel.
But I think the idea is these kits are less-controlled than functional weapons.

>Is it even possible to make something from 99% plastic in Yurop?
There are some all-plastic designs but iirc these are still heavily on the "disposable" side and are mostly single-shot designs without a cylinder/magazine feed etc., with the major improvements in newer designs being surviving a few shots and not exploding into your face when they break.
The thing is that if you want a ghetto single-shot blaster you can do the same thing in a few minutes with a couple bucks worth of plumbing, vs waiting a day for a whole spool of filament to become a nerdhammer with a 10% chance of blowing your fingers off.

But like I said, people are working on the puzzle so they're getting better all the time and I don't know shit.

Personally I think it'd be more fun to work on novel toys like inventing a new kind of BB or dart launcher if you need a quarantine hobby. That kinda stuff is scaleable so you can play around indoors and still kill squirrels if you want to, and it seems more suitable to printing than trying to fire cartridges which only reached their modern designs due partly to late improvements in metal machining.

How do they look when sanded?
I can get a reflective finish if the parts flat enough.

>>1798013
The entire platform.

>>1797978
The flash card isn't dangerous, but it is cheap shit and I had issues with it somehow wiping itself sometimes when I moved it between the printer and computer.
If you care about keeping all of your gcode files on the card, I'd suggest backing the card up to a folder on your PC every once in a while.

>>1797992
Standard practice is to tighten the knobs as much as you can and THEN level the bed. Tighter knobs means more pushing from the springs which means a sturdier bed.
I don't actually know if the bed is even anchored to the printer anywhere except the four corners, so if that doesn't help I'm not sure what the issue would be. Maybe the connection that holds the knobs' frame to the rollers on the rail underneath the bed, or something?

>>1798036
It was the rollers.

>>1798037
