There is a new type of 3D printer on the horizon and it can print up walls with apparent disregard for gravity. The name for this patent-pending technology is Mataerial.
Officially, Mataerial is still very much in the prototype phase. According to the website, the project is the result of collaboration between Petr Novikov, Saša Jokić from the Institute for Advanced Architecture of Catalonia (IAAC) and Joris Laarman Studio.
Mataerial prints by extruding thermoset polymers via a robotic arm. In a process called anti-gravity object modeling (AOM) the polymers immediately harden as they are extruded. The process is so fast that the end result appears to be gravity defying. This new extrusion method will free users up to print on vertical or irregular surfaces.
Take a look:
Mataerial's advances aren't limited to just printing up walls though. Users can also inject, mix and change colors mid stream. That means that gradients are now possible and you don't have to pause to swap extruders out every time you need a new color.
