Description

technical field [0001] The invention belongs to the technical field related to additive manufacturing, and more specifically relates to a high light-shielding polycarbonate wire suitable for fusion deposition and a preparation method thereof. Background technique [0002] Fusion Deposition Modeling (FDM) is an additive manufacturing technology. It uses computer-aided design, based on the principle of layer-by-layer superposition, to heat and melt the wire through the nozzle, and then extrude it from the nozzle with a certain pressure to form a three-dimensional solid part. . Compared with the traditional process, FDM technology has the advantages of no need for molds, short preparation cycle, further simplification of the process, high utilization rate of raw materials, and not being restricted by the complex structure of the workpiece, so it has extremely broad application prospects. Polycarbonate (Polycarbonate, PC) is an amorphous thermoplastic resin with excellent compr...
