A large part of the 3D printers we have is not based on filament but on powder. There are 2 main categories

1. Powder-Based 3D Printing 

In the two technologies Selective Laser Sintering and Metal 3D Printing, powder particles are fused together with a laser. 

A thin layer of powder is rolled out onto a building platform and a laser beam selectively sinters areas which will form a part within the powder bed. In the case of Selective Laser Sintering no support structures are needed, in the case of Metal 3D Printing supports are needed due to heat distribution and stability. 

2. Powder- & Binder-Based 3D Printing: 

We offer 2 technologies which use chemical binders to attach powder to each other: Multi Jet Fusion and Metal Binder Jetting.

Powder is rolled out onto a platform and specific agents are used to bind the layers together. In the case of Metal Binder Jetting additional steps are taken after powder removal including infusion with bronze for the material Stainless Steel (420) Bronze Infiltrated and curing in an oven.
