Vector field-based 3D print path generation for continuous fiber composites

Abstract

The curvilinear print path generation technique for 3D printed carbon fiber composites was proposed. The anisotropic Swift-Hohenberg equation (SHE), which is a generalized mathematical model for periodic patterns in organisms, was applied to generate the evenly spaced 3D print paths. Parameters of SHE that control the convergence of the periodic pattern were optimized for maximizing the structural performance based on the vector field. Then, a 3D print paths were obtained. A carbon fiber reinforced thermoplastic was 3D-printed based on the curvilinear print paths.
