Abstract: The present disclosure is directed, in part, to method for selective thermoplastic electrophotographic process additive manufacturing, the method comprising applying a high-absorbance support material and a low-absorbance part material adjacent to one another: applying radiated energy to the high-absorbance support material and low-absorbance part material such that the high-absorbance support material selectively absorbs the radiated energy and transfers heat to the low-absorbance part material.

Abstract: The present disclosure is directed to a support composition for additive manufacturing, the support composition comprising a soluble support polymer and a finely divided particulate, In certain embodiments the particulate is about 5% by weight to 25% by weight of the support composition. In certain embodiments the particulate is at or below 1 μm weight average particle size.

Abstract: Embodiments herein relate to 3D printing. In an embodiment, a method for printing an article using a selective toner electrophotographic process (“STEP”) includes successively depositing multiple layers of part material and support material, the layers deposited substantially parallel to a first plane: wherein: a) the multiple layers of part material and support material extend in a perpendicular to the first plane; and b) at least some of the layers of part material and support material are separated from each other to form a gap between the layers of part material and layers of support material: application of heat and pressure to the part material and support material such that a portion of the part material and support material flows into and at least partially fills the gap between the part material and support material.

Abstract: Methods and systems for additive manufacturing are disclosed, the methods and systems comprising reducing the amount of support material used, by one or more methods, including inclusion of part material voxels and air voxels within the support regions, using a lattice of part material within support regions, printing one or more skin layers and boundary layers to support the part geometry and surface, and printing support layers in a drafted manner to reduce support material.
