In the rapid prototyping area, technologies used a construction material and a support material to manufacture geometry. The support material is sometimes conserved in the prototyped part and cleared on its outside. This elimination of support material involves a cost for the user. In some cases, the support hasn't structural rules and becomes a manufacturing residual which goes against the aims of ecodesign. This article presents a topological optimization application on a part produced by rapid prototyping. The authors used the numerical simulation to optimize the part's structure and assess the mechanical strength for optimizing he internal topology of a part manufactured by rapid prototyping to save on the material. The results present design solutions which take in account the use context. More particularly, this paper handles the correlation between the virtual and mechanical results. Design For Manufacturing (DFM) approach is used through different mechanical tests necessary to set data of the numerical simulation. Furthermore, the manufacturing characteristics have been integrated to analyze the mechanical behaviors of structure. The study presents an alternative geometry through a design for manufacturing approach and topological optimization of a rapid prototyping application.
