MATÉRIAU DE POLYURÉTHANE THERMOPLASTIQUE POUR FABRICATION ADDITIVE BASÉE SUR UN DÉPÔT SÉLECTIF ET SON PROCÉDÉ DE FABRICATION

摘要

A part material for printing three-dimensional parts with a selective deposition-based additive manufacturing system has a composition having a thennoplastic polyuiethane polymer and a charge control agent. The part material is provided in a powder form having a D90/D50 particle size distribution and a D50/D10 particle size distribution each ranging from about 1.00 to about 1.40, wherein the part material is configured for use in the selective deposition-based additive manufacturing system having a layer transfusion assembly for printing the three-dimensional parts in a layer-by-layer manner.
