During the last couple of years, 3D printing has simply exploded and a plethora of various objects have been created through this method, from limbs to guns. 3D plastic printed guns have been getting quite the momentum in the last year or so, as there has been a lot of experimenting with materials and printing techniques that have allowed printers to create a working gun.
Yet, 3D plastic printed guns are still very unsafe for humans, because plastic in general cannot safely carry an explosive blast without putting the life of the person doing the shooting in great danger.
All this is about to change, because Michael Crumling, from New York, found a new and innovative method of creating handmade lead bullets. The 25-year old machinist used lead shells and has created a reusable bullet that is capable of controlling the entire force of the blast. His technique will also enhance the re-usability of 3D printers and 3D plastic printed guns.
Crumling said about his invention:
It’s a really simple concept: It’s kind of a barrel integrated into the shell, so to speak. Basically it removes all the stresses and pressures from the 3-D printed parts. You should be able to fire an unlimited number of shots through the gun without replacing any parts other than the shell.
By creating this special bullet that allows shots to be fired from the 3D plastic printed gun without needing to replace any parts except from the shell, Crumling just created a deadly weapon that anyone could create in their own home if they possess a 3D printer.
Michael Crumling announced that he will start selling the special bullets online soon. He did a test, shooting 19 rounds from a 3D plastic printed gun that he designed. The gun was printed on the cheap Printrbot with PLA plastic. The gun has some metal holding it together, so it is technically not entirely 3D printed. During the test, the gun misfired a few times, but it didn’t suffer any internal damage.
Officials have started to question the safety of this newly invented method. At least one police official, Andrew Scipione, an Australian police commissioner, has spoken out against the new reusable bullet, saying that the new technique is dangerous.
