Which 3D printer is best for printing a (fully legal) fully automatic lower and what type of filament do I need? Asking for a friend

Damn, sure is bright in here. I wonder whats putting out so much light, the entire threads positively glowing

I like sticking foreign objects in my ass, similar to how a baby wants to put everything in it's mouth. Everything in my house that isn't bolted down has been inserted into my body at least once.

>>64322276 (OP)
Get the right FFL and SOT and so forth squared away, serialize a metal plate, and then feed a two-liter bottle into a hot glue gun from the dollar store and build your lower around the plate.

This sounds extremely ghetto rather than extremely peaceful. What about the semi-auto version?

>>64322334
You can just buy polymer lowers at the store, it's faster and cheaper.

You'll probably want a resin printer for that, not filament.

>>64322397
>You'll probably want a resin printer for that, not filament.
Any recommendations?

>>64322446
I haven't gone down that rabbit hole yet but Anycubic resin printers seem popular. Resin printing involves a lot more fumes and mess than FDM so be prepared for that.

>>64322450
Thanks for the info. I asked AI about this and all it could give me was vague bullshit. AI is the future my ass. I made the OP intentionally provocative but ultimately I just want to make some fun stuff. Have a good one, anon.

/diy/ probably has some threads that can help you with your miniatures and object fixing.

>>64322330
People which the German government doesn't particularly like have a convenient tendency to suffer mysterious heart attacks.

Is the legal process for this actually as difficult as people say? The whole point is simply to have a valid serial number on file, correct?

>>64323643
It depends on the state. Federally there's no requirement for firearms to be serialized unless they're sold. Some states just require a serial number, others require the serial number to be inscribed by an FFL and registered with the state.

>>64322276 (OP)
Bambus are good and easy, a1 for pla+, one of the enclosed ones if you want to do nylon.

>>64323643
Legal process to make a machine gun? You need to file for the correct federal firearms license and pay the special occupation tax, it's involved and expensive but doable.

>>64323674
>>64323643
Oh, I missed that OP wanted to make a machine gun. The simple way to do it is to just print a super safety, the complicated way is to get a type 7 FFL and class 2 SOT, and extra complicated way is to get a type 8 FFL and class 1 SOT, then make your gun in another country and import with a statement of intent from a government agency.

Or you could just not comply.

>>64323705
>Oh, I missed that OP wanted to make a machine gun
It doesn't have to be, I was mostly fishing for replies to get the thread started and I was curious about the process
>The simple way to do it is to just print a super safety,
What does this mean?
>Or you could just not comply.
Hell no, anon, that seems like a great way to go to prison or have mysterious things happen to you like the guy in the OP
>>64323258
>People which the German government doesn't particularly like have a convenient tendency to suffer mysterious heart attacks.
What was his offense? Are Germans able to do this with something akin to a SOT etc similar to Americans?

Thanks to all who have responded

>>64323740
>What does this mean?
There are devices that simulate full auto, forced reset triggers, binary triggers, many designs are available to print, more than are commercially manufactured. They are arguably legal, rare breed settled a lawsuit with the atf that only their frts are legal, but super safeties are different, and while the atf doesn't like them they aren't illegal. Yet.

>>64323812
>They are arguably legal, rare breed settled a lawsuit with the atf that only their frts are legal,
All FRTs are legal according to the terms, Rare Breed is just require to pursue patent infringement lawsuits against anyone else that makes one, which they were doing anyway.

Resolution doesn't matter fory Warhammer 4k games. We actually subject our unit to ft lbs of collision based on damage delt with a serious dropping weights in a guillotine like device. Resin breaks easy so we're moving to filament to save costs on games.

Not sure about "best" but check out the Creality K1C or K2 Pro, they can print in a couple of carbon reinforced plastics that perform similar to aluminum. And don't forget to share your files.

Creality is a shit company and everything they make is overpriced garbage. They're like Bambu if Bambu printers didn't just werk.

Most printers can these days. All-metal hotends are fairly common so it's just a matter of buying a hardened nozzle.
>that perform similar to aluminum.
That's bullshit, not even Markforged continuous fiber reinforcement is on par with aluminum.

>>64324442
>That's bullshit, not even Markforged continuous fiber reinforcement is on par with aluminum.
What would you compare these reinforced plastics with?

>>64322276 (OP)
Do tell, what do you think is so different about a fully automatic lower compared to a plain old semi automatic lower that it would require a specialized printer? Assuming you want to print an AR, PLA+ out of an Ender 3 will do just fine. You dont need anything extra special. If you wanna make full auto, all it is is just an extra pin hole and maybe another label near the selector if you want to be fancy.

>>64324257
Ehhhh his videos are mindless crap meant to impress people who have a passing interest in guns.
>Wow full auto this is so badass
>Could this assassin who killed a guy actually kill a guy?!?

Its whatever. The AK50 stuff is interesting but he never goes in depth enough about the technical stuff for me to be interested and it typically devolves into "WOAH 50 CAL SO COOL!!!".

Arresting someone from Fresno for having a firearm is like arresting a gardener for having a shovel. They clearly need it.

>>64324161

>>64324849
why don't these have a barrel? and why would you cruise around with 6 rounds loaded in a long magazine like that
are they legal if they're only semiauto?

>>64324914
>are they legal if
Without all of the fancy tax stamp things and exhausting legal processes, I mean
Seriously, why can't you just file one form with the local gov't and the federal gov't as required and call it a day. Idk how we have more bureaucracy than Russia

>>64324914
Barrel is short, concealed. The one pictured only has a 3.5" - 4" barrel, almost entirely concealed by the handguard, you can barely see the tip sticking out. He only had 6 rounds left in the gun after a day of fishing and plinking. They are perfectly legal is semi-auto, in the United States you can legally build any firearm you can legally own, with tax related caveats that prevent you from pumping out machine guns for fun. You also can't build a gun for the express purpose of selling it or giving it away, that'd make you a manufacturer, and that requires license and additional taxes to pay.

>>64324914
They do have barrels, usually in the us just a short g19 barrel that doesn't come past the handguard because those are cheap and easy. He probably only had six because he was out shooting the rest, or he just stole one or two out of a few unattended boxes.

They're legal as semi autos in states that don't prohibit pmfs, but his had a stock so was an unregistered sbr federally and cali doesn't like ghost guns.

>>64324566
Here's a comparison. "Onyx" is Markforged's proprietary carbon-filled nylon, "Markforged" is the same filament but with continuous fiber reinforcement. Expect anything that you print to perform more like Onyx than any of the other materials here. Depending on what filament you use, it might be much worse.

I want to second OP's question; what would the ideal printer for firearm components be? I've had people recommend checking r/fosscad, but I don't have a r*ddit account and it doesn't exist anymore anyway, so now that I'm caught up on my mortgage and itching to make a dumb financial decision, what do I piss my money away on? This printer would also be supplementing a cheapo Chinese mini mill and small lathe that I'm also looking to replace at some point. The end goal is to have a pretty decent home shop setup in my garage.

>>64325124
Voron or Ratrig. Or if you're serious about wasting money, Stratasys or Markforged.

>>64325124
You're not looking for anything special, just a normal consumer-tier 3D printer. Consider anything from Bambulabs, or Prusa if you hate money, avoid the real chinkshit brands unless you want 3D printing to be your new hobby. Nothing wrong with the cheapshit printers but they're not tools, they're projects. It's like cars, you don't buy a vintage muscle car when you're looking for a reliable fuel-efficient commuter, and you don't buy a Prius as a project car. Pretty much any modern enclosed printer is perfectly suitable for 2A shit. Avoid the filament trap, retards think every newly announced retarded "engineering" filament will be the greatest thing ever for 2A, they (foreigners and children mostly) love to fight about what filament to use for any given thing and they never know what the fuck they're talking about.

>>64325198
>Voron or Ratrig
It's 2025 bud, it seems you've missed the past few years. Markforged is holding on by a thread, you won't encounter them outside of a university, we phased out our last ones at work in 2023. Stratasys only makes sense on paper if your revenue ends with a b. You don't have to waste your life on a project or spend the price of a house to have a decent printer anymore, you can get off-the-shelf printers at half the price of a self-made Voron that'll outperform it.

>>64325124
Can't go wrong with a p1s, if you want to spend less an a1 in a cardboard box will do most of the same stuff. People vouch for other brands but there generally seems to be more complaints than endorsements, but bambu doesn't have that many issues.

Here's an outdated guide for loose reference.

>>64325221
There is no off the shelf printer that can outperform a reasonably well-built Voron 2.4 that doesn't cost 5+ figures.

>>64325299
But you have to build it?

>>64325320
Yes, is that a problem?

>>64325322
I made a mendel max once upon a time but that's neither here nor there, people generally don't want involved projects to get their tools. By reasonable metrics that other anons point stands. Good on you for making your own but you were just injecting yourself into the conversation to mention it, it isn't a serious recommendation.

>>64325199
>>64325198
What's the most cost-effective but with the important bells and whistles? I want something nice but I don't hate money--value is important.

>>64325344
Bambulabs makes very nice printers that work right out of the box with very little effort, very consumer friendly, highest value for money of any big brand. Big drawback, they're a totally closed ecosystem that sends your data back to Mao. Prusa makes extremely good printers, but they're not made in China, so they're extremely overpriced if you only look at the hardware itself. However, they put a huge amount of effort into refinement. These motherfuckers were winning awards back when they were still zip-tying bearings on. Completely open ecosystem with very few exceptions, huge community involvement and acceptance. People suck Joseph Prusa's cock uncontrollably, insane fanbase. These are the two brands I recommend above all others by a wide margin, especially for a first printer.

Prusa Core One is $1200 assembled, MK4S is $929 assembled, the XL is $2,000.
Bambu A1 is $350, P1S starts at $550, X1C from $800, and the newer H2S and H2D from $1250 and $2000.
I don't how tariffs and shit affect the current situation.

All worth looking at depending on your price range and opinions of the Chinese as opposed to the bearded Czech cult-leader. Both are fine.

Hoffman likes PA612-CF and PET-CF. He shits on practically every other filament, and that has a lot to do with the fact that he primarily prints on an ancient bedslinger without even an enclosure. Anything particularly high temp or warp prone is essentially off limits for him.

His as configured is a sbr, you'd need to find an extra chad cop to overlook that if it wasn't registered. Otherwise if the state has constitutional carry and no laws against privately made firearms or stendos there isn't anything you could get charged with for an fcg in your backpack, as long as you weren't in a no no place. Or it was a disguised firearm, yeah you're probably right, they'd come up with something.

>>64329323
SBRs should of course just be another gun with no special status. That dude was doing something that attracted the po-po and he's paying the price.
That's a cute gun.

Since this seems to be /3DPG/ right now.

Where should I go next with this project, if I go anywhere at all? I made a too large recreation of the MBA gyrojet years ago. And talking about it in a /3DPG/ thread awhile ago made me want to work on it again. But my cad skills have died over the years and I'm having a hard time going beyond conceptualizing any of it. Since I know any gyrojet design isn't of any real use for much of anything unless it has features the ATF doesn't like, like explosive penetrating rounds or massive projectiles about their 12.7mm limit. None of which I'm willing to do. Despite being so cool.

>>64322276 (OP)
Shame so many claps fear exercising free speech these days, I know nothing about 3d printing but I know that you can mix sulfuric acid with any nitrate salt to produce nitric acid which can then be mixed with more sulfuric acid and erythritol to produce ETN.

>>64330043
It's a stupid vestigial law left over from them them trying and failing to ban handguns, on the upside it looks like it's not long for this world. It will be a zero dollar tax soon, braces have won all their legal fights, and it will probably get wrapped up in the near future.

>>64327459
>kek
It wasn't a joke. 3d printing is much weaker than injection molding in general. Also, "carbon reinforced" filaments aren't stronger. The fiber fill isn't to reinforce the material, it's to stabilize it and reduce bending and warping. It increases the stiffness and makes some filaments more printable, but it reduces impact strength and layer adhesion and does nothing to increase tensile strength. Awesome new filaments like PPA-CF are just now approaching what's been possible with injection molding for half a century.

>>64330653
Its been explained a few times in thos thread how to do it legally.

I was listening to a podcast about the war in Myanmar mainly for fcg9 content and they mentioned that their main issue was the lack of air superiority. They could win on the ground, but it didn't matter when the junta forces could then just bomb them.

It made me wonder if a diy anti air solution might be possible. Manpads are right out, pretty hard for industrialised nations to produce, flak shells while easier still aren't feasible. Would it be possible to make a computerized targeting scope though? Plug in the caliber and barrel length, laser rangefinder to get distance and calculate elevation, if it could get bearing and speed somehow it could crunch the numbers and put a dot where you needed to shoot to hit the plane. Planes do take small arms fire in war, generally without too much effect, but if there were groups of people with accurate fire they might be able to take some down.

>>64322276 (OP)

>>64330051
Share and share alike, fren. If it's nearing functionality, someone else might take it up. Otherwise, it might be a good project to get back into CAD.
Gyrojets are the coolest thing that never took off for guns.
>>64330598
I don't want zero-dollar taxes because that's a defacto registry. Same with suppressors. An 11.5" AR should be on the sales rack next to 16" and 20" ARs like ordinary firearms. A short AR with a can running subsonics is the ideal home defense weapon.
>>64330688
Injection molding will always be one of the best manufacturing processes. I'll check out PPA-CF, sounds interesting.
One thing that's surprised me is how few people seem to 3D print molds for injection molding or wax for greensand casting. It's probably highly industry-specific.
>>64330944
To this thread, 3D print fixed wing drones that are can carry 5kg warheads. It'd be a crime to hit pic related, though.

>>64332171
I don't think homemade drones can intercept modern aircraft, unless someone can spin up some jet engine drones in their garage.

>>64322276 (OP)
Just read or watch PSR's posts on Youtube or X.

>>64333189
I could build that drone at home for under $50K, but I'm thinking of something more in the $10-25K range specifically for hunting helicopters and jet fighters.

>>64332171
If you're going to print molds, I'd recommend either carbon fiber or lost PLA (or PMMA) investment casting.

>>64330944
>laser rangefinder
The range of an aircraft is always changing even if it's moving perpendicular to you so the laser would need to be constantly tracking.
Not impossible but you'd need some kind of simplified sight with pre-marked holdovers and a user who won't hesitate. Have the plane in the laser rangefinder crosshair, get the distance and rough aspect angle, pick the correct holdover for the given estimates and pull the trigger within a second.
With a fliegerfaust the shotgun effect and slight delay between launches compensates for slight error.
https://youtu.be/5fskM6iUSbA?si=iAQy7Vp4HD-EA9OD&t=286
Even solid projectiles would punch holes and force the aircraft to get repairs.

>>64333189
Couldn't you just attack them on the runway like what the alcoholic guys to the northwest of the country did in the "operation of arachnid silk trap" did?

>>64334828
Sure. But that's some spec ops raid shit. Ukraine took months to plan and prepare, and intelligence guys like Budanov had experience in doing raids in Crimea prior to 2022.

>>64334773
The laser return changing with the plane's relative position might provide enough data points to gather velocity and direction as well as range. If the laser were independent of the rifle, maybe pointed by a second operator, and held on target I think with enough programming that could send the correct hold to the rifle scope.

Anyone working on anything new?

>>64335573
Right, with a gyro sensor you could track the angle change (like the NLAW) and with a correct range you could automate the holdover.
But at that point you're also accurately tracking the position so you could straight up make a missile guide itself towards the target as long as you keep the track until impact.

>>64322378

>>64337430
The .43r ammo project looks interesting

>>64330944
3d printing seems like the wrong tool for AA fire. Anything smaller than a rifle round isn't going to do much to a plane and you get into pressure concern territory with that.

For a targeting display the only thing I can think of would be some 3D printable attachment that combined a mini RADAR/rangefinder with a programmable sight/GOPRO screen overlay that tells you where you need to lead your shots to hit a plane. The whole thing would be an entire engineering project for something only slightly better than having a second or third dude spraying down a plane, though

>>64333189
In Myanmar im pretty sure they don't use modern aircraft tho. Might be wrong.

Either way it might be worth it for them to look into the taliban's book for evading air strikes

>>64342738
It's a battle of the copes so leave your feelings aside, but the Taliban got slaughtered for sport by kids trying to pay for college or a Dodge Charger.
"Oh yeah we developed tactics to evade air strikes" okay but you still took tens of thousands in losses whenever the Americans stopped shooting back and whipped out their phones. Everyone posting in these threads thinks they'll be the austere religious scholar who takes credit for victory at the end, and not one of the thousands of fat retards who'll be used as A-10 or MQ-9 fodder. I do not want to hear about their tactics because they don't actually work.
Taliban tactics basically assume time is on your side, the enemy is a democratic country that can be easily distracted or turn against policy the populace supported, and you live in such a fucking hopeless shithole that you can keep recruiting even when you're getting clobbered and when the enemy leaves everyone who was neutral automatically flips to your side.
To collapse your own country's state you actually would want to do it as fast as possible because a cascade collapse can lead to change while taking too long allows the state to entrench itself and get more control over institutions that could turn against itself. And also spare your own people from prolonged pain. If the state is authoritarian they won't care if the repression is unpopular, repression will continue until morale improves. If people have actual jobs and businesses they'll tell you to fuck off and stop hiding your FGC-9s behind their dumpsters, they won't have to join you out of economic desperation. Also Islamic insurgencies did get worldwide donations funneled through religious organizations so they could actually offer economic incentive to join, and at a deep enough level worldwide Jihad is actually an unironic grift. If you're a true and honest freedom fighter at most you'll get a few memecoins from tards on twitter.

>>64342729
I was thinking more lidar, I'm not sure what range you could get with a small radar device, and it would be an engineering project but even vaugly accurate I imagine it would be better than a few guys taking pot shots. It's hard to shoot at steep angles, gravity impacts velocity more than drop in those cases, so you have to guess your new zero, you'd also need to properly lead the target. Tracers might be the only thing that makes it feasible, I'm not really conversant on the subject.


Thanks for brainstorming this with me anons, I think it is deserving of more research.

>>64335573
How about if you put the rifle on a gimbal and let the computer aim and fire based on the data it was fed by the targeting device by the operator? If it's attached to the rifle you can't aim at the correct position and keep a target lock. If the human element is removed from firing a fixed and laser guided gun the operator just needs to paint the target, and he'll know if he's on or not. At that point you'd just need to worry about wind conditions and if your slug could travel high enough.

Why do so many retards freak out whenever someone wants to use 3d printers. You know making a gun is legal right?

>>64350622
That's cool, I bet people with registered 40s have a hard time buying grenades

Anyone make a fossberg? It was the easiest build I've done until I pumped it and the follower sproinged out. Still not sure what the issue is.

>>64354919
What variant are you dealing with? The Fossberg was a half-finished project for a long time, several "versions" floating around don't actually work correctly, can't be built to completion, or require parts from other related guns. Issues are common, examples that run well are rare. I highly recommend the PY2A 500/88, the hardware is cheap, it actually works very well, and it'll far outlast a Fossberg build.

>>64354077
It's basically impossible to get actual rounds, everyone uses sketchy unsafe shit that's either visco fused, or will go off the moment it hits something, no matter what/how far.

The holy grail is a printable distance armed fuse with an out of alignment primer

>>64358999
Raspberry Pi-type gyroscope counter?

You'd basically have to install a sparker or bbq ignition system into each round that triggers off the gyro, but with unstable gunpowder compared to more-stable plastique that are drop-and-shoot safe.

>>64357999
I used kaewons rmr remix, might be worth a reprint with your suggestion.

>>64353424
I don't "freak out" I'm concerned for someone's well being. Printers just cannot create a material that is adequate for firearm stresses. And no, knowing your .22 lower can handle 80 shots before something disintegrates and it literally falls apart while firing is not safe.

>>64365415
An improvised plastic weapon is a single use tool for an emergency.

>>64365575
That isn't brought up much, but always seemed like it was good enough for the main legitimate use case. I.e. shooting less than seven rounds at a person or people trying to break into your home or do you grievous bodily harm.

>>64365301
Ah, I'd looked there but just saw files, went back and saw frames.

Don't get a bed slinger

>>64370119
exactly. enclosed core XY printers are the future.
the elegoo centauri carbon is the poorfags quality choice.

so ive been printing g19/17 frames to see what the various settings do IRL and how it feels in hand.

I've been doing
20 walls
5x line multiplier
100% infill
brim
arachne
tree supports
all in ABS. should this be good enough for a fuck around toy till i get my drier in and the ASA-CF and PA12-CF/zytel for serious use, like troll people at shooting matches?

>>64371242
Yeah probably, ABS doesn't have the best layer adhesion so they probably won't be as ststrong as good pla+ but if they feel solid they should run.

>>64371242
What's the ambient during the print? ABS is fine, if you're printing in an 80-100C enclosure. Open air, fuck no, no layer adhesion, trash.

>>64371485
Oddly enough since I got the centauri carbon, ABS has been great for me. with 20 walls and the rest its basically a solid lump of material at the end of print. I blew through rolls of it without a single failure and mostly printed a AWCY CZ Scorpion evo with ABS.

bruh just get a $500 cnc machine and mill it in those aluminum blocks you cast from the beercans leftover from last weeks BBQ. Just be sure to keep the feedrate nice and slow.

>>64373101
why tf would you use ABS when PLA-6/12 exists?
>waaay stronger

I mean, those boos makin switches with PLA and wonderin why the slide is glued shut do make funny titoks though.

bruh that nozzle is a .6 bet and they didn't even anneal the parts kek

>>64373391
>why tf would you use ABS when PLA-6/12 exists?
have you priced it lately? thats why I've used ABS.

>>64373391
Why would you use PA612 when PPA exists?

Haven’t tried printing serious gun parts, but storage for reloading dies and ammo boxes have been nice.

>>64373391
No annealing, good enough. That's the reason I use it.

wats the best way to print a glock frame? rails up, down or 45 degrees?

>>64374412

Rails up is best for dimensional accuracy where all the important bits go.

Rails down is for if you care about the bottom frame surfaces looking pretty.

Idk about 45deg.

I'm a nooby to 3d printing I just have a ender 3 v2-pro-whatever-edition and I make stuff from time to time. never had interest in 3d printing weapons I'd rather just buy a lathe and mill, 3d printed weapons are for countries that are severely locked down like germany, in the US it's totally legal to make your own weapons just not sell them.
anyways I've wanted to upgrade from my ender 3 to a bambu labs one, they're not even that expensive and from everything I've seen they're so much better it's not even funny, which makes sense considering the ender 3 is really outdated and uses a decade-old platform.
as for filament I guess PLA+, I think the one in your picture was designed for ordinary PLA since it's the cheapest and most available. there are stronger filaments (though exactly how "strong" is difficult to quantify as there are different axes of "strength" that matter more or less in firearms design and different companies don't use the same metrics) like CF reinforced though you have to modify your printer to use them

there used to be 3d printing generals on here but paranoid retards who don't understand the legality of homebuilt firearms brigaded them until they died out

Relatively recently several blue states have banned privately made firearms, mostly because of polymer80s ease of manufacture making them a favourite of gang members. Polymer80 was subsequently driven into bankruptcy by lawfare but leftists are still trying to expand the laws by leveraging 3d printing hysteria.

>>64385126
Thanks very much anon, cheers.

has anyone printed the stock from the AWCY scorpion evo?
the way the pack instructions say to print it is without supports on the top. ocra starts throwing a pissfit about it when i try.

>>64374193
everything, screws, bolts, whatever... Eventually little shit like napkin holders and a random replacement cabinet hinge will just come from the printer in the wall.

>>64385651
It's fun to make bespoke toys for my nephew, or replacement parts for things around the house, but it's hard to beat making a $500 gun out of a $200 parts kit.

>>64384954
They aren't. There's a handful of states that require home built firearms to be serialized by an FFL, but it's well established that the second amendment protects the right to manufacture a firearm oneself. That guy wasn't arrested for making a gun, he was arrested for concealed carrying an unregistered SBR without a permit.

>>64378554
Knew your fat ass would find this thread eventually stay on diy

They always tell me it's too much trouble to sell guns.

I can easily print a magazine extension for a 12 gauge? kek lets say a fucking whooping +20 lmfao

>>64391437
You'd have to find or make a spring and attach a bunch of pieces but it sounds like a good meme shotgun.

bought this and it will not stick for shit.
https://www.amazon.com/dp/B07FQCQ17Y
all the other eSUN ABS+ colors stick like hell without glue or whatnot. their ABS+ reds, blues, black, white yellow all stick almost too good.

>>64391437
20 rounds sounds like something that would immediately fail under it's own loaded weight. A short extension or 3d printing an adapter to a metal tube with plenty of supports connecting it to the barrel maybe.

>>64398343
He could use a shower curtain rod attached to one of those super long quiet shotgun barrels

>>64392023
>>64398343
on a second thought seems like a 3d printed(non-metalic) extension would get rekt during even range use.

OP it's a machine called a 3 axis cnc and you use forged billets to create the thing you want.
Out of real metal.
Could also go the 5 axis route but really in the scope of a firearm piece it's just time saver on the machine's production side of things.

If youre asking

>>64322276 (OP)
What kind of filament would be most suited for use as a cheek piece spacer in a target rifle? PLA doesn’t respond well to long days in the sun, I don’t mind just printing more but it would be cool to get something that would last a bit better

>>64415375
ASA if you have an enclosure, if not PETG will probably be fine.

>>64415408
Thanks anon, I’ll do some reading

Here's pretty much all the filaments worth knowing about:
>Polymaker PLA Pro
Other PLAs are brittle and other PLA Plus/Pro/Tough/Whatevers are usually a bit floppy and creep very badly. This is pretty much the best option for anything that doesn't need heat resistance.
>Polymax PC
Other PCs are brittle, PC-PBT blends are usually good but some creep if they have a lot of PBT and they're all generally more expensive. High heat resistance, strong and tough. This is what I'd make 3D2A stuff out of. Requires an enclosure, preferably heated or at least insulated. Very hygroscopic, dry it before printing but humidity doesn't destroy its mechanical properties like nylons.
>PPA-CF (or -CF Core)
Bambu is a bit weaker than other brands since their blend is designed to print well on the X1, which can't quite reach the temperatures required. Even the Bambu is great, the only downside to this stuff is price. Other materials might claim to be stronger than this, don't believe the marketing: PPA is the king. Requires an enclosure and hardened nozzle, ideally you want to be able to get up to around 320C, more if it's a steel nozzle.
>ASA
All brands are more or less the same, eSun is maybe a bit stronger than others but hard to find, it might be discontinued. Not as strong as PLA and not particularly stiff, but it's impact resistant, heat resistant, cold resistant, creep resistant, and UV resistant. Anything that lives outside should be made out of this. Requires an enclosure.
>TPU
Bends. I can't even begin to make a recommendation because what you buy depends on what you're making and how bendy it needs it be. /3dpg/ likes super stiff TPU but it's a meme, PLA is better. Requires an extruder that can handle cooked spaghetti without getting jammed up.

Anything that isn't one of these five is either shit or something super niche that you'll know if you need it.

>>64415545
Cool write up

>>64415545
Actually, I'll recommend Qidi for ASA, I overlooked it before. Although as I noted, they all perform very similarly, you can't really go wrong with it.

>>64345642
>pic
kek

Reposting since this is /k/ related and has more activity than /diy/'s /3dpg/

I went to the gun store and
>"SB TACTICAL SBTI B&T APC/HK UMP Black Side Folding Stabilizing Brace (SBTi-01-SB)"
was on clearance for 45 dollars if I remember correctly. Pic related is my thought process. I would take the angle adjustment picatinny adapter and modify it to be able to mate with this brace.

Its for a mac daddy 2.0. Ideally the brace would swing to the left not to the right but this deal is very good and I wouldn't mind having to deploy the brace every single time since its just a range toy. Another concern is that the bolt handle for the mac 11 model I bought is on the right side and it sticks out. I fear the brace may interfere with the shooting when folded or when attempting to fold due to the geometry.

If am able to fold this brace on the gun without interfering with the bolt handle then I will glue neodymium magnets to the gun and brace so that they stick to each other when folded. Another option would be to figure out how to use a spring hinge thing and integrate it into the adapter I would print bypassing the need for magnets. Thoughts?

>>64420155
Magnets would be easiest and should work fine just to keep it closed. I have a knockoff law folder with nothing to keep it closed and it works okay.

>>64420155
>glue neodymium magnets to the gun and brace
Use a neodymium embedded into the brace, design a recess for it in blender.
Then you can use a little piece of fridge magnet backing on the gun which won't be obtrusive.
The MagSafe ring for Android phones would also work.

Take inspiration from car/phone magnetic holders and rings/stands for phones.

>>64323643
Depends on the state. Business license, 07 FFL, title 2 SOT, and ITAR registration is what you need federally, ITAR being the most expensive. When I had a shop in TX it was about $7k/yr in total and if you weren't actively engaged in trying to sell your product the BATFag field agent might look at you sideways. The experience taught me that BATFags are just bureaucrats like any other, keep your logbook in order, follow the rules, pay your fees, look legit and they don't really care. Most of them have zero knowledge of firearms or their base components. You always run the risk of ending up with some cowboy, but that's not likely if you ive in BFE where they transfer the lifer agents to. If you can generate enough business to pay for the fees and have a friendly LEO then it can be fun as a hobby. My local sheriff liked to play with fun guns so he'd give me a letter of intent for whatever sample I wanted to transfer in, but even letters of intent are a little overblown since you can build prototypes that you want to shop around. The more you are actually engaged in business the less hassle the field agents give you.

>>64425925
You don't need to do any of this shit if you're making guns for yourself. Some shitty states will make you take guns you make to an FFL in the state to have a serial number inscribed.

>>64428017
Correct, simply not complying is much easier because even as an 07 title 2 you aren't supposed to take your manufactured firearms home, so either way it wouldn'tbe your go-to home defense gun. The upside is that post-86 dealer samples are a lot cheaper than transferrables and there's also a way to make pre-86 samples (which are also cheaper) transferrable when you shut the business down.

>>64322276 (OP)
you can find lots of stuff on aliexpress, search for high pressure hydraulic pipes and it'll start you showing in recommendations "related" stuff that people are buying.

>>64428017
The feds don't want you to know this, bit the NFA is based on the interstate commerce clause just like the GCA. So the same legal quirk that saves you from needing an FFL to make a slambang for personal use also saves you from needing a SOT to drill a third hole for personal use. No one has ever been convicted for an NFA violation alone for firearms they made with no intent to sell. As long as you're not a drug dealer or something you're safe.

Ahem.
Any and all forms of home-manufactured firearms are illegal.
Posession of any and all forms non-registered, non-transferable fully automatic firearms are a criminal offence under U.S. federal law.

You may only posess non-transferable fully automatic firearms as samples as a registered dealer.
You may only manufacture ANY form of firearms as a registered gunsmith/manufacturer.

Any person as a regular hobbyist in the firearms community knows these facts full well.

I've been working on an interlinking 4-part discarding sabot for 12ga, holding a 15mm steel ball bearing. Retarded or nah?

>>64468431
I am always concerned about 3d printed plastic shells and cartridges melting and sticking to the barrel and other hot metal parts after repeated firing. Plastic casing exist in modern weapons but its injected plastics of a propriety chemical formula.

Shotgun shells should be fine tho

>>64468497
Shotgun hulls are polyethylene, I don't know why it wouldn't work for other cases since the case doesn't actually support the pressure, it just passes it through to the chamber.

>>64468431
Neat idea, but it's going to see a lot of force and friction. Maybe you could use a carbon filled filament and powder coat the pieces?

>>64468536
Carbon filled filament is a meme. It's more brittle than the standard filament.

It needs to withstand force and pressure for a split second. If piece of shit shotcups can do that, then I think PLA can as well.

>>64468557
You need a material to be electrically conductive to powder coat it, carbon fill does that. It needs to make it all the way down the barrel without bits melting to the bore or the petals fusing to each other, PLA isn't really suited to high temperatures.

>>64364321
Why do you think it's running?

>>64468571

Ivan's what about ammo project solved that somewhat. There are apparently places like Russia where the the blanks for powder actuated nail guns are so bad it still doesn't work but if you can get ramset blanks, primers or blanks plus dummy shells or spent brass you can make ammo. And making it work with those low quality blanks russian might still be a skill issue.

If that's too involved there are models that will take .27 or .22 blanks, then you just need to add an appropriate projectile. Standard practice even before the development of 3d printed guns.

walk a mile in my shoes you spoiled american brat
gunpowder is fine, it's the priming compound that's compromised (for extraction / simply adding a bullet to the nailgun blank after you cut off the crimp while the blank is held with a drill)
also, Ivan's guide is retarded because it does not include proper technique for reloading primers
if you follow his guide your primers will fail horribly because you don't do the shellac / drying step
it's for stupid europeons that can buy primers without a license, imagine that
I can reload ammo just fine, I just have to do extra steps and make a priming compound from scratch or extract it from overpriced imported blanks / extract it from shitty blanks which takes more time

>>64468828
just to be clear what I mean
the priming compound is compromised in most blank so the option of simply cutting off the crimp and putting a bullet there to produce .22 short with 100+ joules of muzzle energy at a 5.6mm 1.5g projectile will not work
also there's something none of you know it's the fact that there are surplus soviet CENTERfire rimless nailgun blanks based on 5.45x39 that contain so much gunpowder you'd have to offload it if you run it as a cartridge
they're also cheap, only 40 cpr
just hold it in a drill/rotating machine, cut off crimp, offload powder and you get effectively a .357 magnum equivalent round
I'm not even talking about 9mm PAK blank rounds that are also centerfire and can be converted into live ammo easily
the issue is that all of those easy to produce rounds require a gun chambered into them and that's something you'll have to make yourself

>>64468849
>the issue is that all of those easy to produce rounds require a gun chambered into them and that's something you'll have to make yourself
That's what you do with any of the fully diy designs, people have just generally done the legwork on what kind of pipe you should get. So break out the calipers, print some go nogo gauges and cross your fingers that the local hardware store or scrap yard has something appropriate. Or hope that the nominal measurements are close enough on chinese explosion proof pipe.
