Abstract
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.
