Purpose To verify the feasibility and evaluate the dimensional accuracy of two Rapid Casting solutions based on 3D Printing technology: investment casting starting from 3D-printed starch patterns and the ZCast process for the production of cavities for light-alloys castings.Design/methodology/approach Starting from the identification and design of a benchmark, technological prototypes were produced with the two Rapid Casting processes. Measurements on a CMM machine allowed calculating the dimensional tolerances of the proposed technological chains. The predictive performances of CAE software were verified when applied to the ZCast process modelling.Findings The research proved that both the investigated Rapid Casting solutions are effective in obtaining cast technological prototypes in short times and with low costs, with dimensional tolerances that are completely consistent with metal casting processes.Practical implications The research assessed the feasibility and dimensional performances of two Rapid Casting solutions, providing data that are extremely useful for the industrial application of the considered technologies. Originality/value The paper deals with experimental work on innovative techniques on which data are still lacking in literature. In particular, an original contribution to the determination of dimensional tolerances and the investigation on the predictive performances of commercial CAE software is provided.
