kkleiner writes "A 3D printing technique has been developed that prints objects that seemingly defy gravity. Dubbed the Mataerial 3D printing system, a robotic arm can print 3D curves on floors, walls, and ceilings, whether the surface is smooth or uneven. Custom-shaped objects are created using a thermoplast that dries on contact with air, which offers an alternative fabrication method to typical 2D layering printing approaches. Though its broad practicality is questioned outside artistic creations, the video produced by the team is mesmerizing."
