Through its proprietary SHS™ technology, BluePrinter delivers professional 3D models comparable to laser sintering quality - more simple and affordable. SHS™ technology uses a thermal printhead as opposed to a laser in SLS machines The thermal printhead applies heat on layers of thermoplastic powder in the build chamber. It allows for free forming of any complex geometry (minimum wall thickness is 1 mm) and can load and print several 3D models.
