We invented a multi-material selective powder recoater
The result is a powder layer composed of more than one powder.
Aerosint invented a unique selective Powder Deposition recoater enabling multi-material 3D printing along some other exciting use cases!
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
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!
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.
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.
A non-contact powder recoater may avoid common issues in fabrication of small and intricate parts in metal laser powder bed fusion
With selective powder deposition we can use virgin material for every part produced by laser powder bed fusion — and prevent waste
