Abstract Previous investigations have shown that the optimization of extrusion dynamics in conjunction with the buildstyle pattern is of paramount importance to increase part quality in Fused Deposition Modeling (FDM). Recently domain decomposition and space filling curves have been introduced for slice generation in FDM. The current work focuses on the implementations of fractal-like buildstyle patterns using Simulated Annealing, Lin-Kemighan algorithms and Construction Procedures based on Nearest Neighbor Heuristics. These computational optimization procedures are able to generate filling patterns that allow the continuous deposition of a single road to fill arbitrary shaped domains. The necessary software modules to produce arbitrary three- dimensional artifacts have been developed and are evaluated with respect to part quality and build time. (Auth abstract) [References: 5]
