Representation and Fabrication Method for Multiple Gradients FGM Part Based on Additive Manufacturing

Abstract:

A simple FGM object with one gradient direction is easily fabricated by the current technique; However, how to fabricate multiple gradients FGM objects is rarely mentioned by some related papers. This paper proposed a representation and fabrication approach to deal with this problem. This approach, termed as minimum fabrication cell (MFC) or allowance fabrication cell (AFC), focus on fabrication of multiple gradients FGM object. In MFC, an arbitrary 3-D model is adaptively sliced into a series of 2-D layers, and each layer is subdivided into a series of MFC or AFC along toolpath. The three linear interpolation is applied to calculate the material for each MFC or AFC, and gradient contribution ratio (GCR) is applied to calculate the material for each vertex on the MFC or AFC.
