« A carbon dioxide laser locally melts a small-diameter glass filament, so it can be deformed. The researchers construct 3D shapes by moving a fused quartz substrate on a 4-axis CNC platform relative to the intersection of the filament and the laser beam. The molten glass is controllably shaped by the interaction with the substrate and pressure from the unheated portion of the filament , as well as by gravity and surface tension. »
