To capture the heterogeneity of biomaterials, a material feature based approach of heterogeneous bio-modelling is presented in this paper. The concept of material feature is defined as the specified material distribution of a certain sub-region within a solid, which is a high level abstraction of design intent. These material features are finally laid down on the function representations, which...

Rapid manufacturing is emerging as a technology that enables the fabrication of three-dimensional heterogeneous objects. Compared to homogeneous objects, the fabrication of heterogeneous objects is very complicated for the processing of material information especially Functionally Graded Materials (FGMs). To take full advantage of rapid manufacturing, some methods to design and fabricate hetero...
