This abstract first appeared for US patent application 20250001690 titled 'METHOD AND COMPOSITION FOR REDEPLOYING A POLYMER FEEDSTOCK
Original Abstract Submitted
disclosed are techniques for converting polymeric powder that has been discarded from a powder bed fusion process into a raw material suitable for an alternative form of additive manufacturing involving extruded deposition. as applied to polyamide powders, the disclosed methods improve suitability of the material for an extrusion process by adding another polyamide species in which the spacings between functional groups on the polymer chain do not follow a repeating pattern. in at least one preferred embodiment, a fibrous filler is also added to further improve dimensional compliance and stability in parts formed by depositing extruded beads of the inventive composition.
