ABS Part Material for Electrophotography-Based Additive Manufacturing

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 copolymer (including acrylonitrile units, butadiene units, and aromatic units), 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.
