Nickel alloy suitable for 3D printing

Engineered materials company Uniformity Labs has improved the parameters for 3D printing its UniFuse IN625 nickel alloy.

The material can now be printed using laser powder bed fusion (L-PBF) at 60um layer thickness, the company said.

The 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 at comparable properties, according to Uniformity.

In one example build of a part typically printed in Inconel 625, Uniformity HPS parameters at 60um layer thickness and 370W power reportedly achieved a 2.1X faster exposure time and comparable or improved mechanical properties compared to competitors’ 40um layer thickness scan strategies.

“Our powders deliver repeatable mechanical properties and surface finish uniformly across the print bed even when printing at throughputs that greatly exceed those possible with other powders,” said Uniformity founder and CEO Adam Hopkins.
