Grizzly (.22-caliber rifle)

The Grizzly and the Grizzly 2.0 is a 3D printed .22-caliber rifle created around August 2013.[1] It was created using a Stratasys Dimension 1200es printer.[2] It was created by a Canadian only known by the pseudo name "Matthew" and told The Verge that he is in his late 20s, and his main job is making tools for the construction industry.[2][3]

The original Grizzly fired 1 shot then broke[2] Grizzly 2.0 fired 14 bullets before getting damaged due to the strain.[3]

Specification

The “Grizzly 2.0″ has 50 percent larger barrel with a rifled bore, a larger receiver and new hammer.[4] In a video posted online by the creator, the Grizzly seemed to have successfully fired a Winchester Dynapoint .22-caliber bullet, like the Liberator .380. The only metal in the Grizzly is a 1-inch roofing nail plus whatever metal is in the cartridge.[5]

Printer

The printer used to make the rifle was a Stratasys Dimension 1200es printer[2] costing $10,000 as of August 2013.[1] It was made using ABS plastic.[3]

"Matthew" said the rifle had taken 3 days to build, and about 27 hours to print it. He revealed it took him 13 hours to print the receiver, 6.5 hours to print the barrel, 5 hours to print the stock and 2 hours to print the rifle's internal parts.[2]
