Abstract: Heterogeneous objects, composed of multiple materials, are now increasingly being used in engineering applications. With the development of new fabrication methods like rapid prototyping (RP), a new dimension is added to manufacture these objects. To manufacture heterogeneous objects by RP, a CAD model is required that contains both geometric information as well as material information. However, current solid modelling techniques focus mainly on capturing the geometric information only. This work presents an approach to model and represent heterogeneous objects by integrating the material information along with the geometry/topology in the solid model. Here, we define new modelling operations for creating and manipulating heterogeneous models and to complement traditional modelling operations through algorithms.
Keywords: heterogeneous solid modelling; heterogeneous objects; functionally graded material objects; STL files; rapid prototyping; CAD; layered manufacturing; manufacturing strategy.
