Material use optimization in 3D printing through a physical simulation algorithm

Abstract This paper focuses on the design of an algorithm for a structure-based infill patterning system for big-scale 3D printed parts. A simple, modular, expandable system is presented that considers the structural logic of printable parts through the voxelization of 3D virtual models into a finite element representation that is used to feed a spring model. Material properties and user customization are discussed. Several ad-hoc solutions, optimization capabilities and simulation results are tested and shown. The use of non-standard, customized nozzle designs and print materials is discussed for further usage capabilities.
