Laser inversion enables multi-materials 3D printing

Selective laser sintering is one of the most widely used processes in additive manufacturing, but it is limited to printing with a single material at a time. Robotics engineers have now developed a new approach to overcome this limitation: By inverting the laser so that it points upwards, they've invented a way to enable SLS to use -- at the same time -- multiple materials.
