Load-dependent path planning method for 3D printing of continuous fiber reinforced plastics

3D printing, to print continuous fiber reinforced plastics (CFRPs) has advantages of manufacturing complex shape and short production cycle. Due anisotropic mechanical properties fibers, the paving direction fibers determines strengths printed CFRPs. In this paper, a novel load-dependent path planning (LPP) method been proposed generate printing for CFRPs, which exactly follows load transmission parts could provide higher properties. A topology optimization is applied simplify original disordered distribution. developed Stress Vector Tracing (SVT) algorithm, paths are generated along with variable spacing adjacent paths. The LPP compared state-of-the-art shown better load-bearing printability.
