Powder Bed Fusion Development
For complex high hardness wear parts
The company is investing in the development of alloys suited for the powder bed fusion process (PBF) which represents the largest existing market and installed equipment base for metal additive manufactured parts. In developing new alloys, the company analyzes both the printability and the “as built” properties vs. materials currently available in AM, as well as those used in conventional manufacturing.
One of the major hurdles to achieving 3D printed high hardness metallic parts has been their tendency to develop cracks. These cracks are the result of stresses developed during part build, given the typically limited ductility of these materials. To address this challenge, NanoSteel worked with global PBF development partners to optimize the parameters of a series of steel alloys to produce fully dense (99.9%) crack-free complex parts. The wear parts produced have hardness values up to 1000 HV, wear resistance comparable to conventionally manufactured M2 tool steels, and a uniform microstructure. These properties were achieved without the need for post-processing such as hot isostatic pressing (HIP) or further heat treatment, reducing production cost and lead times. Further development is currently underway to further improve the printability of these alloys and the resulting properties.
