Following schematics provided by an anonymous Wisconsin engineer, the police department spent $35 and 27 hours to print the "Lulz Liberator" on a $1,650 desktop 3-D printer. During testing, the plastic firearm suffered a "catastrophic misfire" (see image below) that could have seriously injured a person using the pistol, according to New South Wales Police Commissioner Andrew Scipione.
The Australian police used a cheaper printer and weaker plastic to create their 3-D printed gun, compared with the supplies used by Defense Distributed. "We think it's only a matter of time before we see one of these weapons used in a serious crime in New South Wales," Scipione said.
Without an appropriate license, it is illegal to make, possess, or use a 3-D printed gun in Australia. The police commissioner said the government will need to consider regulation of the CAD files used to create 3-D printed weapons.
I can imagine with a hot gun the plastic may deform and yes the gun will explode on the next shots.
I really am surprise the inventors and other commenters had not thought to say something about this earlier. In hindsight it seems rather obvious, lol.
I will all be a time bomb of not knowing exactly when this will happen.
The police should leave 3d printing guns to people with more training and experience. Its for their own safety.
Hey I think if you wrap the Barrel with a kevlar ribbon that might fix the problem. haha engineering students are terrible they want to solve everything. But yeah think that will do it.
Looks like they printed in PLA, which shatters easily.
... and they have set the fill percentage too low.
If it's already illegal to make and possess in Australia, why are they so worried about regulating CAD files? It's stupid. Should we put all of human information back in the bottle too? I mean really, if you teach someone math and science they might use it to hurt someone some day too!
