Abstract
- Abstract In contrast to standard layer based additive manufacturing methodologies, multi-axis material deposition can print structures without the need for support material. However, this method is jeopardized by potential collisions between a depositing unit (nozzle, wire, power and powder sources, etc.) and the already deposited material. The goal of this research is to initiate development of a methodology to check manufacturing feasibility of geometries and generate subsequent process planning strategies. The paper describes a geometry-based concept to decompose the product geometry into discrete volumes by using space partitioning with infinite planes and considering advantages and constraints of multi-axis additive manufacturing. The discrete volumes are used to generate process planning variants and to compute and generate boundary conditions for such process planning strategies. The algorithm generates multi-axis slices that require no support structures because of relative nozzle/workpiece orientation. In addition, the planning tackles more complex scenarios, in which overhangs, nozzle orientation, and gravity can be considered. [ABSTRACT FROM AUTHOR]
