摘要： A part material for printing three-dimensional parts with a selective deposition-based additive manufacturing system has a composition having a thermoplastic 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.

摘要： A part material for printing three-dimensional parts with an electrophotography-based additive manufacturing system, the part material including a composition having a grafted copolymer (including acrylonitrile units, butadiene units, aromatic units modified with polycarbonate and poly(styrene-co-maleimide)), a charge control agent, and a heat absorber. The part material is provided in a powder form having a controlled particle size, and is configured for use in the electrophotography-based additive manufacturing system having a layer transfusion assembly for printing the three-dimensional parts in a layer-by-layer manner.

摘要： A part material for printing three-dimensional parts with a selective deposition-based additive manufacturing system has a composition having a thermoplastic elastomer (TPE) polymer and a surface modifier. The TPE polymer is polyether block amide (PEBA). 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 2.0, 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.
