Selective-area laser deposition and selective-area laser-deposition vapor infiltration are two gas-phase solid-freeform techniques capable of the direct fabrication of arbitrary structures. The wide range of available gas precursors allows unique combinations of materials to be achieved in the final shape. Tailoring of the local microstructure can be achieved by carefully controlling processing temperature, gas partial pressure, and other variables. The versatility of the two techniques can be seen in the fabrication of a structure comprising multiple materials.

“…The development of new manufacturing technologies such as rapid prototyping (Bhashyam et al 2000) or solid free form fabrication (Beaman et al 1997, Jakubenas et al 1998, and the use of new materials like composites (Blasques and Stolpe 2012) requires new optimization techniques. These emerging manufacturing technologies eliminate the high cost of tooling and design changes or material substitution and offer the possibility to achieve multi-materials structures.…”

A heterogeneous or multi-material object is one made from different materials which are distributed continuously or discontinuously and where its properties can be adjusted by controlling the material composition, microstructure and geometry of the object. The development of manufacturing technologies such as rapid prototyping can eliminate the high cost of tooling and can offer the possibility to make multi-materials structures. However the ability to design them is not a trivial task and requires the development or modifications of optimization algorithms to take into consideration the different aspects of these problems. This article presents an enhancement to the ITD Osvaldo M. Querin, Mariano Victoria, Concepción Díaz, and Pascual Martí 2 algorithm which allows it to obtain multi-material designs. Four examples of the topology design of 2D continuum structures are presented to demonstrate that the ITD algorithm is an efficient and reliable method to carry out the layout optimization of multimaterial continuum structures.
