Robotic 3D Printer That Prints Using Sand

3D printing using innovative machines and materials can lead to impressive, unique results--and Jon McTaggart has been paving his way toward bringing together traditional craftsmanship and high-tech manufacturing. His 3D printed "Artifacts" focuses on the "grace of creation" instead of the "precision of outcome," relying on his creating a 3D printer that could print objects using local sands and ground coverings. Read more details about this innovative technique and one-of-a-kind robotic machine in the full article: http://3dprint.com/73723/robotic-3d-printer-artifacts/
