RepRap is a project to develop low-cost 3D printers that can print most of their own components. As open designs, all of the designs produced by the project are released under a free software license, the GNU General Public License.
All of the plastic parts for the machine on the right were produced by the machine on the left. Adrian Bowyer (left) and Vik Olliver (right) are members of the RepRap project.
