Verification through Three-Dimensional Scanning of a Part Made by Rapid Prototyping Technologies

Lost wax casting is a known process for making complex shaped parts. Based on the known technology, one can imagine a technological variant that involves obtaining the model through rapid prototyping processes, and the mold will be made around this model. Subsequently, the model, made of a soluble material will be dissolved, leaving the mold with the corresponding inner cavity. A frequently encountered problem is the need to verify the dimensional accuracy of the model, especially in conditions where its complexity is special. The paper presents the design of the model starting from the shape of the piece to be obtained, the realization of the model using the technology of filament deposition in a molten state and the inspection of the model obtained using a video scanning system.
