“When high tech gunsmith group Defense Distributed test-fired the world’s first fully 3D-printed firearm earlier this month, some critics dismissed the demonstration as expensive and impractical, arguing it could only be done with a high-end industrial 3D printer and that the plastic weapon wouldn’t last more than a single shot. Now a couple of hobbyists have proven them wrong on both counts.
“One evening late last week, a Wisconsin engineer who calls himself “Joe” test-fired a new version of that handgun printed on a $1,725 Lulzbot A0-101 consumer-grade 3D printer, far cheaper than the one used by Defense Distributed. Joe, who asked that I not reveal his full name, loaded the weapon with .380 caliber rounds and fired it nine times, using a string to pull its trigger for safety.
“The weapon survived all nine shots over the course of an evening.”
In actuality, while the gun fired nine shots and survived, the barrel only fired seven rounds without issue. It broke on the eighth round and was replaced for the ninth.
Still waiting to see some ballistics numbers, and also how well the bullet stabilizes (without a non-rigid barrel and no rifling, I don’t see this being effective outside of a few precious yards).
