高強度CFRPの3Dプリンティングにおけるプリントパスと形状設計

抄録

Fused filament fabrication technique has been using in 3D printing of a continuous carbon fiber reinforced plastic. Since the continuous carbon fiber reinforced plastic has anisotropic mechanical property, print path optimization is required in the 3D printing to fully demonstrate the material property of carbon fibers. An open-holed CFRP plate was selected as a simple example to show some print paths. The intuitive and optimized print paths based on a genetic algorithm to maximize fracture strength were discussed.
