Abstract: Part materials for additive manufacturing applications include materials with a fluoropolymer processing aid (material-FP). These materials include one or more thermoplastic polymers and one or more fluoropolymers as a processing aid. The material-FP is used to build parts with additive manufacturing systems. Parts built using material-FP have improved physical properties including improved strength in the z-direction of the parts. Composite systems such as reinforced filaments with the material-FP also have a higher density.

Abstract: A support material for use in an additive manufacturing system to print a support structure for a three-dimensional part. The support material includes a base resin that is substantially miscible with a part material used to print the three-dimensional part, and has a glass transition temperature within about 10° C. of a glass transition temperature of the part material. The support material also includes a dispersed resin that is substantially immiscible with the base resin, where the base resin and the dispersed resin are each thermally stable for use in the additive manufacturing system in coordination with the part material.
