Uniformity Brings High Speed, No Compromise Metal Additive Manufacturing to the Industry with its Material and Print Solutions.

December 15, 2022 – Fremont, CA – Engineered materials company Uniformity Labs (Uniformity) announces the availability of its UniFuse™ 316L ultra-low porosity stainless steel powder. This high throughput feedstock exhibits best-in-class material properties. The UniFuse™ 316L powder and optimized print processes have been used to create various parts in various industries with great success.

Developed by an in-house team of world-leading materials scientists and 3D printing innovators, Uniformity Labs UniFuse™ 316L 90um 400W Performance mechanical properties are superior in UTS, YS, elongation, and density compared to industry standard lower layer thickness parameter sets. Uniformity Labs UniFuse™ 316L ultra-low porosity powder and High-Performance Scanning (HPS) achieve an approximately 3X faster build time when compared to the competitor’s lower layer thickness scan strategies targeting best-in-class mechanical properties. This throughput improvement is typical for UniFuse™ 316L builds. Compared to similar layer thickness builds, Uniformity Labs UniFuse™ 316L and HPS achieve far superior mechanical properties and build uniformity across the build platform with significantly increased throughput.

Higher bed and tap densities enable Uniformity powders to deliver improved mechanical properties and consistent performance across the build bed, even at high-speed build rates and thicker layer printing.

316L is an austenitic stainless steel that is perfect for demanding environments and applications, such as parts exposed to marine, pharmaceutical, or petrochemical processing, food preparation equipment, medical devices, surgical tooling, and consumer products such as jewelry. It is known for its corrosion resistance, high flexibility, and excellent mechanical properties at extreme temperatures.

“The application of Uniformity 316L 90um stainless steel delivers mechanical excellence for our customers who require materials that perform to the highest standard in extreme conditions,” said Uniformity founder and CEO Adam Hopkins. “Our powders deliver superior mechanical properties, surface finish, printing yield, and part reliability, and allow one machine to do the work of several.”

In addition to materials already available, the Uniformity team is continually developing new materials and processes to make 3D printing accessible to all industries and applications.

Notes:

  1. Properties are given for the laser-melted product printed at 90um layers. Auxiliary operations may influence the displayed properties. Auxiliary operations, e.g., heat treatments or surface modifications by coating processes, bead blasting, etc., performed at Uniformity Labs or the customer will affect mechanical and physical properties.
  2. The indicated density limits are valid for the mean density of a component. For complex and geometrically unfavorable shapes, the local segment density can deviate from these limits, and therefore materials properties may be affected.
  3. Materials properties stated in the table above have been determined on the basis of ASTM E8-21.
  4. All mechanical characteristics are typical mean values valid only for the indicated nominal density level and will vary from printer to printer.
  5. Roughness measurement according to microscopy in accordance with DIN EN ISO 4287.
