Static modeling of heterogeneous objects
Abstract
Different from typical CAD modeling, the modeling of heterogeneous objects (HEOs) has material type and its distribution as the new design variables. The core of HEOs modeling is combining the geometric structure together with the material design to realize a special function of the object that is not possible with a single material. Using a standard file format and interface to 3D printing devices, the final static models can be directly used for digital manufacturing. This chapter describes (1) structural models based on the voxel method and the contour approximation method; (2) addition of material information to the structural model to generate static models of HEOs; (3) point cloud ...
