摘要
Due to the advantages of control over shape and properties, multimaterial parts have potential for a broad range of biomedical engineering applications. A type of multimaterial part processing method based on digital design and manufacturing has been put forward to solve the problems associated with multimaterial part formation. A modeling platform for a heterogeneous object (HEO) part based on a material distribution control function and hierarchical contour loop was designed and utilized to characterize the material distribution in the HEO model. The hierarchical algorithm of the point color and surface texture based on the topological structure was studied and provided the basic data for the material construction area. An HEO part was fabricated using a custom-made 3-D printing system. The results showed that the digital processing method could effectively solve the problem of HEO part material definition and could realize the integrated design and manufacture of the geometry, material and function of biological parts.
