Hi folks, I've been involved in the Free, Libre, and Open Source Software, Open Hardware, and desktop fabrication movements for over twenty years. I maintained the first version of the RepRap 3D printer in a Free Software CAD system, and founded the Michigan RepRap Users Group. I co-founded the Open Graphics Project, and participated in development of the first Open Hardware phones via OpenMoko. I've helped to 3D print human stem cells with lasers and consulted on the development of the 3D printer aboard the international space station. As partner in mUVe3D I help produce the industry's most open and flexible SLA liquid resin 3D printers. I've also co-founded and aided in the development of several community and maker spaces. These days I am focused on Replimat, a construction system which requires only a few hand tools, is compatible with other building systems, and makes more of itself. Thanks for considering supporting me and my work!
