Metal Additive Manufacturing Conference - MAMC 2023

Outokumpu plans to commence production of spherical metal powders using a Vacuum Induced melting inert Gas Atomization (VIGA) plant in Krefeld in the latter half of 2023. Additionally, collaborative efforts with entities such as IEHK - Steel Institute RWTH Aachen University, and Swerim metals research institute have led to advancements in pilot-scale development of special-grade powders, specifically 253MA and 904L, which can offer a wider range of possibilities for Additive Manufacturing (AM) industries. The upcoming presentation will highlight the following achievements:

• Identification of the atomization window required for producing 253MA
  and 904L powders.
• Evaluation of the characteristics of the produced
  powders to determine their suitability for AM technologies.
• Conducting printing and post-processing trials for
  the 253MA grade.
• Development of printing parameters specific to the
  904L grade.
• Performance of mechanical testing on AM 904L parts, with a
  subsequent comparison against cold-rolled material.

These achievements underscore the relevance of these developments within the additive manufacturing industry.
