Rapid Prototyping techniques can guarantee great competitive advantages if applied to the production of tools and moulds for the realisation of technological prototypes or pre-series.In the field of metal casting, innovative low-cost techniques have extended Rapid Casting possibilities, based on the 3 dimensional printing technology making use of a ceramic material. Complex cavities can be obtained quickly directly from the CAD model, complete of cores and air vents, which are suitable for casting light alloys. The process performances in terms of dimensional accuracy and surface finish still have to be evaluated.The research regarded the development and production of a metal prototype by means of an innovative rapid casting technique, referred to an aluminium casing for the automotive field. Initially CAE tools were applied to model the casting process, achieving the concurrent product-process development. Then, a technological prototype was obtained by rapid casting, using the ZCast technique. The metal prototype was measured on a CMM machine to calculate the dimensional tolerances ensured by the proposed technological chain.
