Metallic additive manufacturing process faces many costs factors that can be reduced in the very first step: design process. Topology optimisation is a very strong numerical tool to deal with time to design reduction. In this paper, an innovative approach combining process hybridisation (DMLS and Cobapress), topology optimisation and lattice structure is developed. The method is applied to an automotive suspension knuckle to reduce mass and costs factors during the manufacturing while maintaining the mechanical performances. The design is dedicated to additive manufacturing process. The paper details each step of the design process and the first results obtained using this approach.
