Abstract

An automated 3DCP toolpath optimization method is developed and demonstrated on a 4 m × 4 m post-tensioned modular floor structure. The method includes (1) buildability optimization via normal-driven spherical shape analogy, (2) curve number reduction through adaptive Booleaning, (3) “nonstop” globally continuous toolpath with detouring travel lines, and alternative methods of (4) curved slicing and (5) infill generation.
