In the world of rapid prototyping and production of metal components, it is imperative to have the proper gas atmosphere to produce quality parts. To meet the metallurgical and dimensional quality standards required in 3D printing, argon and nitrogen are commonly used to provide inert atmospheres. Using sufficient flow rate and purge duration helps to avoid undesired chemical reactions and thermal deformation of consolidated parts, as well as ensure a safe production environment.
Air Products has extensive applications knowledge in surface/bulk treatment of metals to help additive manufacturers optimize the gas selection, supply mode, and purity for improved part processing.
