Selective Powder Deposition by Aerosint

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

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. 


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

Benefits of our Selective Powder Deposition Recoater


Fast multi-powder deposition.

Material Flexibility

Works with wide range of polymers, metals and ceramics.

High Resolution

High resolution and 3-dimensional control over powder voxel placement in powder bed.

On/Off low contact recoater

Alternative recoating method to hard, soft or roller coaters. Precise control over material quantity deposited.

Main use cases for SPD

Multi-Metal L-PBF Printing

Who has never dreamed of printing parts that combine various metals like copper / steel?

Multi-material powder deposition is one of the keys to achieve this.
Possible applications are: Injection mold tooling with high cooling efficiency, bi-metallic wear parts, heat exchangers and many more!  

Binderless Printing

Indirect sintering of metal or ceramic parts without binder is made possible by our multi-material recoater. 

Multi-material powder deposition technology can elevate ordinary die-pressing technology to the production of highly customized parts.

Dual-Metal L-PBF

Aerosint’s recoater has been integrated in a L-PBF system from Aconity 3D GmbH , making it the first commercial multi-metal L-PBF printer in the world. 

The printer is today available to research driven organizations for purchasing.
