We love desktop 3D printers, except that it's hard to do anything useful with the flimsy, thermoplastic results. However, the folks at Inventables want to change that with Carvey, a home-based CNC machine that etches your designs on wood or brass. Since there are plenty of digital carving machines out there already, the team differentiated Carvey by claiming that you can go from initial sketches to a final product in under five minutes. As such, it includes the company's Easel design software, which runs in a computer web browser (you can also use any CAD and machine control software).
