摘要：
Based on the root cause of principle error in layered manufacturing, the paper proposes an adaptive slicing algorithm, which uses a section between the upper and lower layers as a layered section, and it minimizes the characterization of solid surface roughness delta or volume error S. The value of delta is about half of what the traditional method gives, furthermore S is greatly reduced. The algorithm is applicable to slicing solid in 3D finite difference mesh generation. A program of 3D finite difference mesh generation is developed, and the precision of mesh generation is greatly enhanced.
