Rapid prototyping of wax models for investment casting

Abstract

This article discusses making wax models for precision casting technology. Our chosen method of making these prototypes consists in printing the positive of the model on 3D printer, which is then molded into rubber. The resulting rubber mold is used for casting the wax models. The focus of the article is mainly on the quality, speed, and accuracy of making wax models, while they will be compared with commonly produced wax models.
