Founded in 2016 out of Gardena, California, 3DEO makes production metal components using proprietary metal 3D printers. The business model involves supplying low-cost parts directly to customers, and Mr. McCallum says that they’ve managed to integrate the finishing machining processes into their printers as part of their technology. They claim to be directly competitive with traditional manufacturing in terms of part pricing, material properties, and quantities. Given that we’ve seen some pretty sizable funding rounds going into “on demand manufacturing” firms like Xometry and Fictiv, they’re going to need to scale quickly to stay in the game.
