Rapid Investment Casting (RIC) is an advanced manufacturing technique that combines the capabilities of Additive Manufacturing (AM) technologies to fabricate complex metal parts through the creation of wax models for investment casting. The success of this process relies heavily on the dimensional quality and precision of the initial wax patterns. The growing adoption of Material Jetting Technology (MJT), a type of AM process, for crafting these wax patterns necessitates a thorough investigation of properties imparted by this approach.

The analysis involves a direct comparison of the final 3D-scanned metal parts with the corresponding CAD model, offering insights into the accuracy of the MJT-generated wax patterns. A structured light projection 3D optical scanner was utilized to capture the 3D models of casted parts, and Geomagic Control X was utilized to point out the dimensional discrepancies between the scanned and CAD models. Additionally, the research provides a comparative analysis between MJT and Vat-photopolymerization (VPP) methods in RIC processes, contributing to the understanding of the impact of Additive Manufacturing (AM) on dimensional precision. The findings aim to enhance the knowledge surrounding the efficacy of MJT in RIC, paving the way for advancements in precision casting.
