In this work, the production of ceramic moulds for aluminium casting using a stereolithographic apparatus (SLA) is presented. Design/methodology/approach – Suspensions of silica powders in a photoreactive resin were used in a standard SLA equipment in order to build green parts. SLA, SLA-250 (3D System, Valencia, CA) was modified in order to fabricate a ceramic green parts. Findings – A characterization of mechanical properties of the material samples was performed. Finally, moulds for aluminium casting were obtained either using the stereolithographic part as a green mould, either by pyrolisis of the organic binder and subsequent sintering at high temperature.
