“3D printers build objects by cross-section, one layer at a time from the ground up—gravity is a limiting factor. But what if it wasn’t? Using proprietary 3D printing materials, Petr Novikov and Saša Jokić say their Mataerial 3D printing system is gravity independent. The duo’s method allows a robotic arm to print objects on floors, walls, ceilings—smooth and uneven surfaces. It uses a thermoplastic that cures on contact with the air, not unlike the 3Doodler, a Kickstarter project that places an extruder in human hands to draw 3D forms on the air.”
