Powder & Bulk Solids: From Nanoparticle Agglomeration Problem to Perfect Tungsten Powder Flow by George Paffendorf

The customer, an expert in 3D printing, was looking for a way to “coat” (sometimes referred to as “treat”) its submicron tungsten powder for improved flow during the 3D printing process. The small size of the particles presented a significant challenge. Agglomeration–the tendency of particles to clump together–threatened to disrupt the delicate flow needed to maintain even distribution and bed density for successful 3D printing.

Known for tackling complex particle problems, the Advanced Powder Solutions team understood the need to adapt existing machinery to the unique weight and handling demands of tungsten. By carefully embarking on a collaborative journey with the customer and analyzing customer-specific requirements, APS helped in developing a customized process.
