A thermoplastic material
Powder Laser Sintering is a 3D printing technology which manufactures parts by agglomeration of material particles. Employed materials are generally thermoplastics or metals in powder form of 50 microns of granulation.
Laser fusion
The powder is agglomerated by successive stacking up of about 0,1 mm thick layers. On each layer, the material is transformed by a laser beam which brings the energy needed to reach the fusion point.
