There is a strong interest in utilizing Additive Manufacturing (AM) for tooling applications. This implies that the tool manufacturer and the tool designer fully understand the possibilities, as well as the limitations, of the developed AM product. Considering the expected growth of the AM technology, development of alloys tailored for AM and suitable for tooling applications is of great interest. The aim of the present investigation was to evaluate the performance of newly developed stainless precipitation hardening AM tool steel for plastic injection moulding applications. Those material attributes which are critical for injection moulding applications, such as polishability, wear and corrosion resistance, along with the expected mechanical performance were evaluated for the material after it was processed with several AM systems. The results demonstrate the benefits when considering the AM produced material for tooling applications and highlight the importance of quality considerations, process control and post treatment.
