Self-organized 3D-Printing Patterns Simulated by Cellular Automata

Abstract

Abstract. 3D printers are usually used for printing objects designed by 3D CAD exactly, i.e., deterministically. However, 3D printing pro-cess contains stochastic self-organization process that generate emergent patterns. A method for generating fully self-organized patterns using a fused deposition modeling (FDM) 3D printer has been developed. Melted plastic filament is extruded constantly in this method; however, by using this method, various patterns, such as stripes, splitting and/or merg-ing patterns, and meshes can be generated. A cellular-automata-based computational model that can simulate such patterns have also been developed.
