World's first 3D-printed rifle gets update, fires 14 shots

But the weapon, .22-caliber long rifle made out of ABS+ plastic dubbed "the Grizzly 2.0," still ended up developing a crack after the 14th and final shot. It's also quite cumbersome compared to modern automatic firearms, as it requires reloading after every shot. Matthew further noted that the spent bullet cases were difficult to remove, requiring him to unscrew the barrel and shove a stick into it in order to get them out. Nonetheless, it's clear he's making rapid improvements on the project. He previously told The Verge that he's in his late 20s, and his primary job is making tools for the construction industry, where he has access to a Stratasys Dimension 1200ES industrial 3D printer which he used to print the gun's parts.
