Described as a "mega-scale free formprinter" by its makers, the massive aluminum structure uses sand, which it forms back into a material that's like marble.
The idea of the 3D printer determining the form of the items it produces intrigues Neri Oxman, an architect and designer who heads a research group examining new ways to make things at MIT's Media Lab.
The easy-to-use Form software (compatible with any 3D CAD package), custom-formulated printing materials, and Form Finish post-processing kit complement the beautifully simple printer to make desktop 3D printing as easy as pushing a button.
