In this process, layers of ceramic powder are placed in the installation space of the 3D printer by means of a rotating roller. The powder bed created in this way is printed layer by layer with a binder fluid that bonds the powder particles together. A CAD file of the component to be produced provides the template for the print, which is then divided into slices with the corresponding layer thickness. After a drying phase, the component created by this process can be demoulded from the powder bed and then fired.







Advantages

High process speed:
approx. 30 seconds /
Printing layer
Several different components can be printed simultaneously.
No support material necessary:
The layered components are supported by the surrounding powder
Complex geometries:
Overhangs, undercuts, holes etc. are possible.
Due to the low
coating thickness (standard 100 um), even filigree components can be manufactured with a high degree of accuracy.

Disadvantages

High porosity:
Since the powder is not highly compacted in the process, the components have a relatively high porosity.
Low strength:
In accordance with the high porosity, the components have a comparatively low strength.
Demoulding:
The printed components must be removed from the excess powder. Depending on the complexity of the component, this can be very time-consuming.
