The Shuty-MP1 is a hybrid 3D printed gun made from mostly 3D printed components and some parts from a standard handgun. According to the creator, Derwood, the design is 95% 3D printed, with the bolt and both receivers being made entirely of standard PLA from Atomic filament and all of the parts were printed on his Fusion F306 3D printer. The mostly 3D printed handgun fires live 9mm rounds from its 3D printed magazine, and it can get off eight shots in less than ten seconds. Derwood has already fired more than eight hundred rounds using the MP-1 and it can manage to fire two full magazines of ammo in a row without sustaining any damage.
