A facet cluster-based method for alternative build orientation generation in additive manufacturing
Year: 2016
Type: preprint
Abstract: Build orientation determination is an important pre-processing step in Additive Manufacturing. To identify anoptimal build orientation, there are two main tasks, generating a set of alternative orientations and evaluatingthese alternatives with pre-set criteria. To solve the first task, currently there are two categories of methods,exhaustive computing and continuous surface decomposition. However, for exhaustive computing methods, theinfinite original alternative orientation space is an obstacle, especially when considering multiple objectives.While the other type of methods have difficulty on surface separation and shape boundary recognition whenfacing complex CAD models. To tackle of these obstacles, this paper introduces a new method applying astatistical tool to form facet clusters for decomposing an STL model in a discrete way. The formed facet clusterscan be used to efficiently generate meaningful alternative build orientations and can also be used to predictsurface quality distribution over a part model for further process planning or design iteration.
