Defense Distributed is a collective that raised $20,000 in BitCoins to lease a 3D printer and develop and prototype a 3D printed pistol. Stratasys, the manufacturer of the printer, seized it from the home of Defense Distributed's Cody Wilson, after a heated email exchange in which the Stratasys counsel said that "It is the policy of Stratasys not to knowingly allow its printers to be used for illegal purposes. Therefore, please be advised that your lease of the Stratasys uPrint SE is cancelled at this time and Stratasys is making arrangements to pick up the printer." Robert Beckhusen writes more in Wired:
