Selective Powder Deposition by Aerosint

Aerosint invented a unique selective Powder Deposition recoater enabling multi-material 3D printing along some other exciting use cases! 

We invented a multi-material selective powder recoater

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.

Use cases for multi-powder layer deposition


Here colored PA12 (red) and TPU (white)


Here Titanium (grey powder) and Alumina (white powder)


Here glass (inner cube slightly darker) and Alumina.

We have tested our recoater with a wide range of commercially available polymers, metals and ceramics. Reach out if you want us to test your materials. 

Some of  the use cases for multi-powder layer deposition

Multi-Material Printing

Who has never dreamed of printing parts that combine various materials like copper / steel or PA12 /TPU ? 

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, custom orthoses with elastomeric materials for skin-contacting point surfaces and many more!  

Zero Waste Printing

Powder-based 3D printing of high performance polymers is extremely wasteful.

The Aerosint multi-powder deposition process places expensive build powder only where needed, and inexpensive, non-fusible support powder everywhere else, virtually eliminating waste of unfused build powder.

Binderless Printing

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

The recoater stacks layers containing both object powder and a support powder with a higher processing temperature. In a furnace sintering step, a carefully chosen set temperature causes the object powder to selectively consolidate. No binder is needed, resulting in process efficiency and high part density.
