Uniformity Labs Launches UniFuse IN625 Nickel Alloy for Metal Laser 3D Printers

Uniformity Labs has announced the availability of its UniFuse IN625 nickel alloy and optimized parameters for laser 3D printing of 60µm powders. The company developed a high-density, multi-modal Inconel 625 powder as well as 3D printing parameters for a layer thickness of 60 µm for 3D printers with 400W lasers. Uniformity Labs powder can also be printed with common scan parameters at different layer thicknesses and laser powers, with improved mechanical properties, or with increased laser speed and throughput.

For an example design of an Inconel 625 printed part, Uniformity has proven that HPS parameters with a layer thickness of 60 µm and a laser power of 370 W can achieve 2.1 times faster exposure time as well as mechanical properties compared to competitive settings scanning, with a layer thickness of 40 µm.

The company also claims that the greater densification and optimization of the particle size distribution of Uniformity multimodal powders help produce more uniform and denser layers on the build plate, allowing for more repeatable part builds at high throughput. According to the company, this allows its powders to be used to produce parts with improved mechanical properties and faster 3D printing speeds.

This announcement follows the recent availability of a range of steel, aluminum and titanium powders under the brand name UniFuse for L-PBF technology and UniJet for powder bonding technology, bringing our material portfolio to 13 high density powders, with many more approaching availability.

The mechanical and density properties for the printed nickel alloy UniFuse IN625 are shown below:

  • layer thickness 60 µm, 400 W
  • 99.98% density, 2.1x higher throughput with comparable features – compared to competitive 40µm layer thickness printers
  • tensile strength (Rm z bar) – 948 ± 8 MPa
  • tensile strength (Rm x y bar) – 1039 ± 9 MPa
  • yield strength (Rp0.2 with bar) – 585 ± 11 MPa
  • yield strength (Rp0.2 x y bar) – 695 ± 26 MPa
  • elongation at break (A z bar) – 47 ± 4
  • elongation at break (A xy bar) – 40 ± 6
  • surface roughness in z-direction, untreated (µm) 8.5 ± 1.2
