Rhode Island Patent of the Month – March 2021

Metal 3D printing provides a way to rapidly produce complex parts in less time than classic manufacturing. Many of these methods use a solid-liquid-solid phase transformation.This method is limited to a few materials as many materials have a tendency to crack in the heat treatment. The Nanosteel Company, Inc, is developing a new method which produces stronger products using specific metal alloy compositions. 

NanoSteel is an advanced materials company specializing in steels designed with their nano-scale microstructures. Their method uses a layer-by-layer construction of a metallic part. These alloys can be made using an iron, chromium, or molybdenum base. Melting the alloy down to a molten state, the metal can be formed into a multilayered form of the desired product. Each layer, once solid, is between 2-200 microns. For reference, the average human hair strand is 70 microns wide. This layered method increases the printed products tensile strength and hardness which reduces cracking after heat treatments. 

Are you developing new technology? Did you know your development work could be eligible for the R&D Tax Credit and you can receive up to 14% back on your expenses? Even if your development isn’t successful your work may still qualify for R&D credits (i.e. you don’t need to have a patent to qualify). To find out more, please contact a Swanson Reed R&D Specialist today or check out our free online eligibility test.
