The Finnish Additive Manufacturing Ecosystem (FAME) has published a new white paper based on research conducted through FAME Campus collaboration. The study examines the condition of EOS MaragingSteel MS1 powder after 50 build jobs and approximately 1,600 hours of exposure, providing encouraging insights into powder reuse in industrial additive manufacturing (PBF-LB/M).
Reliable industrial adoption of metal additive manufacturing requires practical knowledge of how materials and processes behave over time. Powder reuse is an important part of this understanding, affecting material efficiency, production costs, and confidence in part quality.
The new white paper combines operational experience from FAME Campus with the material expertise of EOS. The study found that the powder remained in excellent overall condition, with no major changes in its measured properties. The findings also highlight the importance of appropriate powder handling, sieving, and storage practices.
The white paper was authored by Antti Seppälä from EOS Electro Optical Systems Finland Oy and Henri Ervasti from Etteplan Oyj with a foreword from Markus Korpela, DIMECC Ltd.
The publication demonstrates how FAME Campus and collaboration within the wider FAME ecosystem can turn shared industrial questions into useful knowledge. By making practical findings available to the additive manufacturing community, FAME aims to support better-informed decisions and the continued development of reliable, resource-efficient manufacturing processes.
