WZR - Binder Jetting

Binder Jetting is a form of additive manufacturing, often referred to as powder bed based 3D printing. The Binder Jetting process is based on inkjet technology. Similar to an inkjet printer, a substrate, in this case a ceramic powder surface, is printed using a print head. The template for the parts to be printed is provided as a CAD file, which is digitally divided into slices of the desired layer thickness (usually 50 – 200 µm). Instead of a ink, a liquid binder is used to bond the powder particles together. The powder is applied and printed layer by layer, whereby the powder bed moves down one layer in the z-direction after each printing process. The layers are applied by a rotating roller in x-direction, the print head moves in xy-direction. Thus the component is built up from bottom to top, with the remaining, unbound powder taking on a supporting function during this process.
