Aerosint has developed a powder recoating system for additive manufacturing in powder bed technologies. This system can spread two or more powders in a single coating. The new technology allows for different approaches, such as multi-material printing, printing without a binding agent for indirect AM processes, and the option of zero-waste printing in the powder bed process (LBM, EBM, SLS, etc.), where the powder can also be used as support structure when manufacturing parts. The properties of the powder currently degrade during the process itself, decreasing the recyclability of the material. The use of a different powder to support the parts during the process will reduce the waste of quality base materials and therefore improve recyclability.
