【摘要】 异质零件的动态模型是使用微四面体，以材料特征为顶点，通过材料向量分布角度调整设计动态变化，实现材料的渐变或突变效果。结合STL格式，给出的模型可以直接用于3D打印制作动态模型。基于色彩映射材料函数的彩色四面体模型及模型可视化方法，既可用于彩色模型3D打印，也可用于梯度功能材料3D打印。更多还原

【Abstract】 The dynamic model of heterogeneous parts uses micro tetrahedron, takes the material feature as the vertex, adjusts the distribution angle of material vector to realize dynamic change, and realizes the gradual change or mutation effect of materials. Combined with STL format, the given model can be directly used to make dynamic model in 3D printing. Models can be used for both color 3D printing and multi-material 3D printing. The visualization offers an interactive design tool for modeling HEOs and therefore is one key element in additive manufacturing technologies.更多还原
