Metal Powder FastForm 316L 15–53 Microns, 5 kg

Achieve Industrial Precision with FastForm 316L Metal Powder, 5 kg

For industrial Additive Manufacturing that demands exceptional corrosion resistance and outstanding mechanical toughness, the FastForm 316L Metal Powder, 5 kg is the definitive material choice. Designed specifically for Laser Powder Bed Fusion (LPBF) systems, this powder ensures your prints achieve near-100% density — bridging the gap between complex digital geometries and functional, durable metal parts.

Operational Advantages of FastForm 316L

The success of metal 3D printing depends heavily on the physical behaviour of the raw material inside the build chamber. We go beyond basic specifications to understand how this powder interacts with your laser and recoater system.

Superior Flowability and Packing Density

A critical failure point in SLM printing occurs when powder clumps during the recoating process. FastForm has engineered this 316L stainless steel powder with a Hall flow rate of ≤ 18 seconds, ensuring rapid and uniform layering across the build plate. This exceptional flowability translates into a higher apparent density (≥ 4.1 g/cm³), minimising internal porosity. The result is printed parts that are not only visually detailed, but mechanically robust for demanding sectors such as medical implants, marine components, and chemical processing equipment.

Optimised Particle Size Distribution

With a strictly controlled particle size distribution of 15–53 μm, the FastForm 316L Metal Powder, 5 kg sits in the sweet spot for modern fibre laser systems. Its spherical morphology, verified through SEM analysis, enables consistent melting and consolidation. Furthermore, the low oxygen content (≤ 600 ppm) prevents oxidation defects during the sintering process, ensuring finished parts retain the ductility and oxidation resistance inherent to high-quality 316L steel.
