Mihai Viteazul 1, 300222 Timişoara, Romania b Institut de Formation Technique Supérieure Charleville- Mézières, Université de Reims-Champagne-Ardenne, 7 Boulevard Jean Delautre, 08005, Charleville-Mezieres, France Abstract In the context of intrinsic sustainability of fabrication techniques belonging to powder metallurgy, recent developments in rapid tooling based on Selective Laser Sintering (SLS) has proved to be an effective method for reducing time-to-market for products belonging to very different industries. Current applications already include production of die inserts, active parts for different tools and devices, orthopedic implants etc. Fabrication routes usually include indirect laser sintering of an iron based powder, burning out of polymer binder, heat treatment in controlled atmospheres and final infiltration with non-ferrous alloys. Since infiltration alloy represents a significant proportion of the final material, optimization of bronze compositions could be an important way to increase mechanical properties and durability. In order to improve conventional bronze grades that are used for infiltration, a study has been performed to determine the influence of tin on both mechanical properties and infiltration capacity of the copper-based alloy. Results of infiltration with different alloy compositions have been evaluated by mean of optical and electronic microscopy to estimate filling quality, as well as mechanical testing to determine mechanical properties of final material.
