basically what the title says, always print in abs kids, also don’t worry, I’m safe
Interesting. I don’t 3d print. What happened and why?
gun made boom, but in the wrong direction, because my friend printed the barrel with a weaker material
edit: typo
Did you send the model or pre-sliced files? Parameters like wall-thickness and vase/non-vase can have a huge influence on structural integrity.
You stupid dumbass…
His idiot friend test fired a brand new weapon in-hand.
forgot to mention: it fortunately only was a 40gr .22lr
You test fired a 3D printed gun you had no hand in making… but your friend is the idiot? 🤔
Yeah, using the wrong kind of filament accidentally is understandable and doesn’t say anything about anyone’s intelligence.
Takes a real moron to test fire a brand new experimental gun in their hand, and then cry about it and blame their friend when it inevitably goes sideways
I think you misrepresent something here, I clearly told my friend which filament to use and trusted them, that’s why it’s mildly infuriating
Using the wrong filament isn’t Darwin Award worthy. Test firing a newly manufactured weapon with your hand is. And that would be true even if this wasn’t an experimental home-made design…
And in your opinion, how would I have better represented someone test firing a gun in their own goddamn hand?
Wait, you’re right. After your reply I think “moron” was way too lenient of me.
Please tell me you weren’t wearing eye or ear protection, that’d make this even better.
ofc I weren’t! eye/ear protection is for soy boys!
Wrong filament and I bet 30% infill too! ;)
nah, it felt heavy enough to be at least 100% infill, this is the reason there are no plastic fragments in my hand
100% infill leaves no room for overflow/swell. Anything more than that is going to cause issues too.
at least 100% infill
I meant it as in at least it was 100% infill not as in it was 100%++ infill
ok, I’ll admit I’m kinda at fault here to
You test fired a 3D printed gun you had no hand in making
I mean, I think that that’s reasonable. But that seems like a “get behind something protective and pull the trigger with a string” territory. Regardless of who printed it.
If there isn’t some kind of standard safety checklist for printed weapons, I really think that there should be if lots of people are going to be printing these things.
Can you… uh… explain for someone who has no idea what you’re talking of?
Their friend used the weaker kind of material to make a gun and test fired it by hand. So the gun exploded, hurting them.
I can’t believe this ended badly. Seems like you just can’t catch a break.
I usually see people mount it on a vice and use a string from a distance away, plus behind blast shields.
Guns are dumb
Guns are inanimate.
People who do dumb shit like this are dumb.
It’s common to call products dumb when they have the marketing strategy of tricking gullible people into thinking they need it.
Guns are still dumb.
High risk, low rewards
Enjoy your rewards
Fuck the haters, OP.
They will thank you for your experiment & sacrifice when they have to resort to printing these. When the only weapon left against the fascists, that confiscated all weapons, is this.
I mean I did something stupid when hand fireing it, so they got a point ig
Would carbon fiber be better than abs?
just gonna mention oatian gate here
I tried looking it up and and didn’t find anything What’s the reference?
sry, meant ocean gate (I’ll edit it)
Not really. Most CF filaments are PLA with a chopped strand fibers added in, and the strength gains are marginal.
You can get CF-impregnated ABS/ASA but it’s really hard to work with and liable to be weaker unless you get everything perfect.
Ultimately the best approach is to go the same route as the Defcad people, printing the lower receiver of an AR and paying cash for the rest (or maybe also stock and frame. The important bits line the breach block, barrel and other things that get hot would still be metal.)
The thing with that is that the LR is technically “the firearm” as far as the ATF is concerned.
why tf you need a handprinted gun. i bet my ass this isnt legal
I’m a hobby gunsmith who happend to buy a 3d printer
And you’re absolutely sure it had turned out differently with ABS? I’ve tried different filaments and to me it seems they’re all just plastics… I tried some mechanical parts and they all broke soon enough. So I’d say it’s likely an ABS gun will explode, too. Don’t try that with your other hand! This is more Darwin award level, than infuriating.
I belive an abs gun should be able to fire 2-3 shots, also it’d probably crack instead of explode (according to people who tried it that is)
I really can’t tell if you’re being serious. I strongly suspect this is some rage-bait or excercise in creative writing… In case it isn’t: I’d advise you to re-watch the old Mythbusters episodes. See how they do experiments and treat safety and dangerous things. You generally also don’t look down the barrel of a loaded gun. Sure, it isn’t supposed to go off and blow your head off until someone also pulls the trigger… But: This is how accidents work. It’s literally the definition of it. And accidents do happen. Every single day.
And you’re constantly begging for more accidents to happen. Your friend wasn’t supposed to print it in PLA… That ABS wasn’t supposed to do more than crack… The design should have worked…
And then you do the experiments and find out what happens in reality. That’s the scientific approach. Your friend didn’t use ABS, layer decoherence is a thing and even ABS will exhibit catastrophic failure on first try and not just crackle. The whole design might be a failure. I applaud you for learning things… But just don’t have your fingers and limbs in-between you and that learning experience! Idk, clamp it down with a vise and use a rope to pull the trigger. Watch the Youtube videos of lots of other 3d printed guns explode… Hide behind the shed so the fragments won’t hit your eyes.
And in case this is some creative writing project: I’d recommend you to visit 4chan. That’s more a place to post gore, bait and you’ll find some people who like this kind of stuff.
nah, this is fr and I DID learn out of this experience, I just wanted to share it, so everyone can be reminded how important safety is
edit: also the reason I posted a screenshot of my camera roll is, because I did something illegal
Fair enough. Take care. Glad you learned something. That’s the most important bit. I was a bit wary at first. It’s too easy (generally) to just blame someone else, not learn and repeat the same mistake. And I wasn’t sure if you were doing this. The only correct approach is to instead have a good look at ourselves and ask: “What could I have done differently, to prevent a situation like that from happening (or escalating).”
When doing experiments and handling dangerous stuff, it is of utmost importance to factor in mistakes and even unlikely scenarios. You always need more than one layer of protection/safety. And generally don’t do things unless you have a good grasp of consequences and what might go wrong and how to mitigate for that.
Stay safe, and a speedy recovery.
