Abstract This paper discusses the modeling and simulation of multi-materials for additive manufacturing. The mechanical property analysis of multi-materials is essential for developing a very feasible product. To that aim, a few steps are necessary, firstly, a database of those multi-materials is created. Secondly, stiffening technology is introduced together with an alternative optimization method. Finally, the material minimization technique is developed through the simulation results. Two methods are proposed for material optimization. The first method saves the materials twice, and the second method improves the stiffness characteristics of the materials. The developed method generates promising results, and it is applicable to composite geometries. The finding shows that the technique helps to reduce production costs at large.

1 Introduction Material optimization is a widely used technique at the initial stage of manufacturing to minimize the development cost. With the existing FEA software, the optimization can be easily performed according to the boundary conditions applied to the structure. Relying on the data of one of the * Md.

topology optimization software ParetoWorks, the product’s weight reduction can reach more than 50% of the initial structure [1]. The restriction of the optimization is the requirement of fully established design rules, which is not yet defined for multi-material products [2]. Therefore, there is a need to develop a material optimization method and apply it to multi-material 3D-printed products to minimize the production cost. Furthermore, it should be integrated into the newly developed multi-material SLS 3D printers. SIMP optimization method used for shape optimization is implemented based on rational approximation on material properties, but it is merely for cellular structures and is not appropriate for composite materials [3]. Topology optimization function in ANSYS software considers the composite material characteristics. The methods utilize a pre-developed database in SLS-based 3D printing, as discussed in [4]. The analysis of topology optimization based on the use of topology optimization function in
