Abstract We consider layered manufacturing as a fabrication technique for metallic, functional parts. While commercial machines still do not support metals, several research systems are already in existence in universities and research laboratories. Such systems can create multi-material parts and can vary material composition within the layer. A key enabling technology for the automation of such layered manufacturing systems is heterogeneous solid modeling. Current CAD systems do not provide the capability to deal explicitly with material heterogeneity. We provide an overview of this new field, propose a method for modeling and representing material in addition to geometry and topology, and discuss some related research.
