The weight reduction was achieved by optimizing the topology using the SIMP method. first, the part was geometrically modelled by the Catia V5R21 software, then an ANSYS solver is applied to choose the appropriate material and study the loads and stresses acting on the component of the multi-component system "perforator" a mass reduction up to 64% will be achieved on the topological optimization of the studied part. then, the obtained results are compared to other results of the literature. this significant reduction in mass and volume without altering the mechanical characteristics of the system, with an improvement in performance. Implementing the topologique optimization using ANSYS software, this reduction influences the manufacturing time as well as the cost of the part. finally, the implementation of the SIMP method using ANSYS allowed us to determine an optimal configuration of mechanical components for 3d printing according to pre-established parameters with sufficient strength.
