🏅 Best Poster Award at EBAM 2025: Pushing the Limits of Tungsten in Additive Manufacturing

We’re proud to announce that our CEO, William Sjöström, has been awarded the Best Poster Award at the EBAM 2025 Conference for his groundbreaking work in additive manufacturing.

William’s research, titled “Reduced tungsten process development by a dual-gradient parameter approach in PBF-EB”, marks a significant step forward in the processing of chemically reduced tungsten using Electron Beam Powder Bed Fusion (PBF-EB).

🔬 Highlights from the Research:

• ✅ A dual-gradient parameter approach accelerates material development.
• 🌱 Chemically reduced tungsten—a more economically sustainable feedstock—was successfully processed.
• 🌀 Even irregular, faceted-shaped tungsten powders proved viable in the Freemelt ONE system.
• 🔥 Both line and spot melting techniques were used effectively.
• 🧱 The process achieved fully dense parts, with densities exceeding 99.8%.

This work is the first outcome of a collaborative effort between Mid Sweden University, Freemelt AB, Sandvik, and Wolfram, aimed at industrializing additive manufacturing with advanced materials.

“This is good news for our customers who are constantly looking to reduce their cost of manufacturing,” says Dr. Mikael Schuisky, Business Development Manager at Sandvik.
“The fact that the very first outcome receives an award underscores how the three parties together are pushing the boundaries of additive manufacturing technology.”

🌍 Why Reduced Tungsten Matters

Reduced tungsten is produced via a thermochemical method where tungsten oxide is reduced by hydrogen. This eliminates the need for plasma treatment, making the process more cost-efficient and sustainable.

The award-winning work demonstrates that electron beam technology can handle challenging powders and unlock new possibilities for high-performance components in demanding industries.
