A new startup is developing a 3D printer unlike any we've seen before, and one that could completely revolutionize the way brick façades and structures are made. Pixelstone, a spinoff of Dutch company Lab3D, has designed a printer that prints small brick cubes, or "pixels," in digitally predetermined patterns to form smooth brick surfaces. The process is faster than traditional bricklaying, and, according to the company, uses 90% less energy. A working prototype has been developed, and the printer is expected to hit the market in one and a half to two years. Read more at 3DPrint.com: http://3dprint.com/126562/pixestone-brick-3d-printer/
