NOVARRG (Northern Virginia RepRap Group, also at [masked]) was formed to support the 3D printing platforms available to hobbyists. We host build groups for the Prusa Air printer and collaborate on new printing technology and experiences.
If you have a 3D printer already, bring it! (Makerbot, ToM, Prusa, Up!, Mosaic, Printrbot, etc). Otherwise just bring your interest in this technology and ask questions!
