The RepRap is an open 3D printer design whose goal is to produce a printer that can copy itself. Now, Joris from i.materialise says, "The Open3DP team at the University of Washington's Solheim Rapid Prototyping Laboratory have succeeded in cloning the plastic parts of the RepRap Prusa. The Prusa is the most accessible 3D printer the RepRap project has and this development allows for the quicker and cheaper production of 3D printers. By making molds the plastic parts for the 3D printer can be made in under half an hour. Furthermore, the team is going to give away the STLs of the molds so that people worldwide can make their own Prusas."

Cloning the RepRap Prusa in under 30 minutes

(Thanks, Joris!)
