It's very similar to the Projet x60 (formerly ZPrinters) or projet 4500 series printers from 3D systems. The printer lays down thin layers of powder material then goes by with a bonding agent and color as it prints. The prints are relatively cheap because after the print you can vacuum up the excess material and use it in subsequent prints.
