A powder metallurgy (PM) process to fabricate alumina parts through indirect Selective Laser Sintering (SLS) of spherical alumina-polyamide composite powder particles is presented. The PM process includes powder production, SLS, debinding and furnace sintering. In order to improve the density of the final alumina parts, the density of the green parts are optimized through different strategies: remelting, cold isostatic pressing (CIP), quasi isostatic pressing (QIP) and infiltration. Further, the geometrical quality of the green parts and final alumina parts is assessed.
