Understanding how the surface area of metal powders influences Additive Manufacturing
The surface area of particles in metal powders is affected by particle size, shape, roughness and porosity. Even spherical gas atomised metal powders exhibit surface areas much higher than suggested by their size.
In this article, Dave van der Wiel, Director of Technology Development at NSL Analytical Services, discusses the topic and explains why the knowledge and use of powder surface area is a critical parameter in the metal Additive Manufacturing process.
