Multimaterial Additive Manufacturing by Aerosint

Aerosint invented a unique selective Powder Deposition (SPD) recoater enabling multi-metal L-PBF 3D printing along some other exciting use cases ! 



Aerosint Selective Powder Deposition Recoater process explanation

The technology

The Aerosint powder recoater consists of patterning drums which selectively deposit fine powder voxels in a line-at-once manner.

The result is a powder layer composed of more than one powder.

This is an alternative to single material powder bed fusion systems.

The technology applies to multiple additive manufacturing techniques like Laser Powder Bed Fusion (L-PBF), Binder Jetting, and Die Pressing.


Multi-powder deposition unlocks some very unique use cases in Additive Manufacturing, Powder Metallurgy and beyond.
