摘　　要：针对异质材料零件内部的多种材料无序分布且难以表达的问题,提出了一种基于多色距离场的异质材料模型建模方法.利用三维切片软件将该方法所建的异质材料模型进行切片分层得到二维切片数据,依据二维切片数据生成微滴喷射的驱动信号,在此基础上运用数字化微滴喷射技术对异质材料模型进行成型加工,测试结果表明了该建模方法的可行性.For the problem of the material distribution disordering inside the heterogeneous part and their difficulty to express,the paper presents a method of modeling heterogeneous materials based on multi-color distance field,and a three-dimensional slicing software is used to slice and layer the heterogeneous materials constructed by the method to obtain two-dimensional slice data.Then the drive signal of spray droplets is generated with two-dimensional slice of data as a basis.Finally,heterogeneous materials parts can be modeled by the digital droplet jetting technology.Testing results show the feasibility of the method.
