Firing 3D-printed 9mm bullets!
Firing 3D-printed 9mm bullets!
Attention: I do know that I didn’t wear eye-protection, and you do not have to point it out. We consider these rounds very low risk as they are light and have very small powder charges. I appreciate your concern, but it was pointed out a few moments after the video first was posted.
[Warning – loud volume]
One of my friends owns a 3D-printer and prints all sorts of crazy things with it. A while ago, we were discussing different gun related parts that could be printed, such as grips. After a while we had the bright idea of printing actual bullets for reloading.
I can’t remember seeing 3D-printed projectiles being fired through a rifled barrel yet, so this might a “proof of concept” video.
As the video shows, the tests were successful. All bullets fired and the Glock didn’t blow up. When it comes to accuracy, the 1gr loads showed some potential, while the 3.8gr loads seemed to shoot high and left.
Hopefully, we’ll get around to do some medium testing sometime soon. We do not have access to ballistics gel, but we’ll figure something out.
Bullet specs:
Material: PLA (prolylactic acid, biodegradeable)
Extruder temp: 195 C
Bed temp: 70 C
Layer height: 0.2mm
Nozzle diameter: 0.4mm
Bullet weight: 13gr

lmao
THIS IS WHY I NEED 3d PRINTER & ammo machine
Anyway you have got to buy the bullet and change the part with the gunpowder and put the 3d printed bullet together with it, so it doesn’t have sense in costs.
Be cool to see a gel test
Very interesting how quiet the round was and how it didn’t cycle the weapon. Would be very interested to see what this looked like with a 3d printed suppressor. Also have you considered printing with a hole in the round and inserting something heavy and metal to make them potentially lethal?
This are not 3d printed bullet from what I understand, only a part is printed. Obviously you still need the powder and the shell…
Infinite ammo
Man, where can we find the file for these?
I wonder what the agents think of me watching this in the UK 💀
I can see a softer spring, for the reload 😉
That might be the solution for my throttled AEA HPmax Airgun.
Pellets or Slugs do cost around $10-14 for a pack around 100pc. That’s ok for range shooting, but for some inhouse training with distances below max 10m, could be accurate enough… maybe even better use a mold and inject the filament through the extruder, to get the most accurate plastic bullets. Others do this with hot glue sticks and molds.
Add an steel ball in the plastic bullet to give it some whight. 😄
imgaine using these in USPSA major trying to get to 170 PF with a 1 grain projectile lmaoooo.
You got some knarly z banding lol
would this be considered a war crime 😂😂
“this’ll teach that bastard to call his hits”
WARNING !! it depends on the kind of plastic which you use, BUT ABS CAN CONTAINS UP TO 30% OF GLASS. As you know, glass is a highly abrasive material. I worked in a company which provided injection plastic molding and the biggest problem was piping. Because these plastic pellets were extremely sharp and made holes through the 1/4 inch stainless steel pipe. You definitely don’t want this in your 1000€ barrel.
This is a suppressed dream, no slide action, subsonic, and can just eject the case direct into a container so no picking up shells off the ground
Normal dudes just use wax…..
From watching your video I see that you are having problems getting your glock to properly cycle after firing off a 3d printed round. A possible fix for this is to pack in more powder. You have a decent idea, but I think you are possibly making squids.
What was receipe?
Why was the recoil so much lower though?
Say again your last.
bro made a green tip 55 6
This video sucks it doesn’t even show how much damage the plastic would do because the targets are already beat up
That’s sooo cool I wonder what damage it does to wood stuff like that maybe even a 22 could be like less lethal
you could make them even stronger by using PC or PETG filaments
Can you talk
would putting a gas check on the rounds allow them to be fired near power ?
holy, 6 years ago 3d print stuff look like shit compare to my 99$ machine.
I’m watching the Last Of Us and it had me thinking of unlimited bullets
I wouldn’t say it feeds without problems because it is a semi auto and you’re manually having to put a new round in the chamber.
That bullet was moving slow asab 😂😂😂😂😂
Round doesn’t cycle because they are too light, not enough gas pressure being built up in the barrel for those wondering
The main issue at this point is going to be the weight of projectile. Secondary concerns would be related to fouling the rifling with plastic, especially after many rounds are fired in succession, the hotter the barrel gets the more plastic left behind in the barrel.
Put at least 4 grain and a lighter spring that can still load the cartridge into the chamber (if that’s possible)
Has anyone tried resin? More fragile but also more accurate?
No eye pro?? That’s just irresponsible!
you get caught with any of this in California expect the 3d printer you can own 3d printers and you will go to prison
Did any of them cycle the gun? Where can I get the STI file for these?
Hot glue into a Lee bullet mold is way faster and cheaper.
if u print it hollow and put a ball bearing inside of it i think it could penetrate armour
Try this for a revolver, bud
How’s the penetration I wonder 🤔
This was interesting, but soo many unanswered questions. What did the barrel look like after a magazine of this stuff? if it were lined with plastic I would not shoot real ball ammo anymore until it was cleaned. How does the heat of the barrel affect the polymer bullet before it leaves the barrel, multiple rounds with a quick rate of fire ? I imagine stove pipes, FTF, FTE and many other issues. I imagine you could do more with tail to make it more accurate, coat the bullet to make it more barrel friendly, have cutouts to insert pellets for more weight.
3d printed bullets are better in a revolver in my opinion dont have to worry about the cylinder rotating
i want to see them off a resin printer
in really surprised the bullets remained intack, I could imagine future versions With different designs I’m curious how they would perform at the range! great video thanks for sharing!
Id love to see the FPS
