Submission + - World's First 3D Printed Castle is Now Complete - On to Printing a House Next (3dprint.com)
ErnieKey writes: A Minnesota man, named Andrey Rudenko has officially finished 3D printing a castle in Minnesota. It is constructed using a 3d printer that extrudes a concrete mixture in 10mm high layers. The project took a couple months to complete, and the results turned out quite incredible. The castle's turrets were printed separately, and it took 7 adult men to lift them and put them on top. With his method now proven, Rudenko now plans to 3D print an entire 2-story home, in one piece, including the roof.
