Squashed-Slice Algorithm Based on STEP-NC for Multi-Material and Multi-Directional Additive Processes

Even though additive manufacturing is receiving increasing interest from aerospace, automotive, and shipbuilding, the legacy approach using tessellated form representation cross-section slice algorithm still has essential limitation of its inaccuracy geometrical information volumetric losses final outputs. This paper introduces an innovative method to represent multi-material multi-directional layers defined in boundary-representation standard model process complex sliced without missing volumes by proposed squashing operation. Applications a bending part, internal structure, industrial moulding product show assurance building original shape volume during comparison with method. The results that boundary te geometric expected improve was barrier applying various metal industries.
