We’ve seen 3D printers being used to make everything from houses to organs. It proves that 3D printers have the potential to democratize how we make everything, for better or worse. Depending on how you feel about the subject, the next 3D printing marvel could be one or the other.
A member from the gun forum AR15 thinks he may have created and successfully tested the first 3D printed firearm. He used a Stratasys 3D printer from the mid-90s to create a .22 pistol. He claims to have fired over 200 rounds from the 3D printed marvel and it still works fine.
