As manufacturing methods advance today, the use of additive manufacturing and reverse engineering applications in casting technologies is becoming increasingly important. Modern and traditional manufacturing methods each have their advantages and disadvantages. Integrating these methods will make the production process more efficient by utilising their advantages. In this study, additive manufacturing and reverse engineering, which are among the modern manufacturing techniques in casting-die technology, are defined, examples are given in which areas they are used, and some suggestions are presented. Information was given about new developing technologies, especially about very fast molding in prototype casting studies.
