1. A part material for printing three-dimensional parts with an electrophotography-based additive manufacturing system, the part material comprising:
- a composition comprising;
a thermoplastic material having a heat deflection temperature ranging from about 100°
C. to about 150°
C. wherein the thermoplastic material comprises polycarpolactum (PA6), polyhexamethyleneadipamide (PA6,6), polyhexamethylenenonamide (PA6.9), polyhexamethylenesebacamide (PA6,10), polyamide 6/12 (PA6,12), polyenantholactum (PA7), polyundecanolactum (PA11), polylaurolactam (PA12), or mixtures thereof; and
a charge control agent;
wherein the part material is provided in a powder form having a D50 particle size ranging from about 5 micrometers to about 30 micrometers and having a particle size distribution with a D10 value, a D50 value and a D90 value wherein a D90/D50 particle size distribution and a D50/D10 particle size distribution are in a range of between about 1.0 and 1.4 and wherein the D90/D50 particle size distribution and the D50/D10 particle size distribution are within about 10% of each other; and
wherein the part material 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 using heat and/or pressure.
