The automotive industry has Henry Ford, the airline industry has the Wright brothers and the 3D-printed guns movement has … Michael Crumling? According to a report from Wired, 25-year-old Crumling, a machinist from Pennsylvania, has created a steel-reinforced bullet that he says will allow a 3D-printed gun to fire repeatedly without breaking.

According to Engadget, Crumling has been testing his steel-reinforced bullets on a 3D-printed gun he built himself.

“It’s a really simple concept: It’s kind of a barrel integrated into the shell, so to speak,” Crumling told Wired. “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.”

While the stronger steel shell may help 3D-printed guns created with cheap plastic last longer, the effort that goes into producing these special bullets is substantial. According to The Verge, Crumling spends an hour creating each round. Fortunately, one need only shell out 27 cents per round for the materials.

Crumling has shared the design for the .314 Atlas rounds on his website: http://mikescustomweaponry.wordpress.com/2014/11/05/314-atlas/

What do you think of Crumling’s bullet design? Will it make 3D-printed guns more practical? How will lawmakers respond? Sound off in the comments section.
