Powder portfolio enables the printing of complex, high hardness parts and crack-free gradient designs. The NanoSteel Co. has expanded its range of additive manufacturing (AM) material capabilities to support metal 3D printing … of complex, high hardness parts and the ability to customize properties layer-by-layer through gradient material design.
The company leveraged its 2014 breakthrough in AM wear materials to print a bearing and impeller using the powder bed fusion process. These parts were measured to be fully dense and crack-free, with hardness levels >1000HV. By delivering these properties in functional parts, NanoSteel takes a significant step in the development of metal powders that enable affordable, robust industrial components produced on-demand through the 3D-printing process.
Building on this milestone, the company used a combination of high hardness and ductile alloys to create a part featuring a gradient design. NanoSteel worked with Connecticut Center for Advanced Technology to generate part samples using freeform direct laser deposition. This single additive manufacturing process achieved a seamless transition between the hard and ductile properties without subsequent heat treatment. … (read more)
