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 melt-processable consumable material configured as a feedstock for use in an additive manufacturing system includes a polymeric matrix comprising one or more polyaryletherketones, wherein the polymeric matrix comprises between about 10 wt % and about 50 wt % of the total weight of the feedstock. The material includes radiation shielding particles dispersed within the polymer matrix wherein the radiation shielding particles comprise between about 50 wt % and less than 90 wt % of the total weight of the feedstock.
