Engineered materials company Uniformity Labs has made available its UniFuse IN625 Nickel Alloy and optimized parameters for LPBF printing at 60um layer thickness.

The company has designed high-density multimodal Inconel 625 powder and 60um layer thickness High-Performance Scanning (HPS) parameters for printing in machines with 400W lasers. Uniformity’s powder can also be printed under typical scan parameters at different layer thicknesses and laser powers with improved mechanical properties or with increased laser speed and throughput.

In one example build of a part typically printed in Inconel 625, Uniformity HPS parameters at 60um layer thickness and 370W power achieved a 2.1x faster exposure time and comparable or superior mechanical properties compared to competitors’ 40um layer thickness scan strategies. This throughput improvement is reportedly typical for UniFuse IN625 builds.

The higher tap density and optimized particle size distribution of Uniformity multimodal powers create a highly uniform, denser powder bed – yielding more repeatable part builds at the highest throughput. This enables customers to utilize Uniformity powders to produce parts with improved and stable mechanical properties, even while printing at significantly higher build rates.

“We continue to demonstrate outsized value to our customers, harmonizing AM materials and processes to deliver production-scale additive manufacturing,” said Adam Hopkins, Founder and CEO of Uniformity. “Our powders deliver repeatable mechanical properties and surface fin

ish uniformly across the print bed even when printing at throughputs that greatly exceed those possible with other powders. Our ‘No Compromise’ approach to AM enables our customers to realize cost-effective serial production.”

Uniformity Labs is addressing the industry challenge of economically achieving serial production in AM by developing and producing its highly advanced ultra-low porosity metal powder feedstock. Currently in production under the product brands UniFuse (for LPBF) and UniJet (for binder jetting), and with its High-Performance Scanning strategies, Uniformity Labs has improved the ability to produce high-quality parts repeatedly and at scale – allowing additive manufacturing to become an increasingly better-established serial production technology.

This announcement follows the recent availability of a range of steel, aluminum, and titanium powders – bringing our the company’s portfolio to 13 high-density powders, with many others nearing availability.

Mechanical and density properties for as-printed UniFuse IN625 nickel alloy include a 60um layer thickness at 400W, 99.98% density, 2.1x the throughput with comparable properties compared to competitor 40um layer thickness printing, Ultimate Tensile Strength (Rm z bar) – 948 ± 8 MPa, Ultimate Tensile Strength (Rm xy bar) – 1039 ± 9 MPa, Yield Strength (Rp0.2 z bar) – 585 ± 11 MPa, Yield Strength (Rp0.2 xy bar) – 695 ± 26 MPa, Fracture Elongation (A z bar) – 47 ± 4, Fracture Elongation (Axy bar) – 40 ± 6, surface roughness in the z direction – no treatment (um) 8.5 ± 1.2.
