Additive ManufacturingCopyright: © GHI
In recent decades, the field of additive manufacturing has undergone rapid development. Due to the flexible production of components, this type of manufacturing is of increasing importance for research as well as for industry. One of these processes is direct inkjet printing, which enables the production of individualized and complex components.
The focus of the devision "Additive Manufacturing Processes" lies in the material and process development for the Direct Inkjet Printing (DIP), which has been developed and patented in-house.
DIP can be used as an additive manufacturing process (AM) for ceramic materials. By multilayer printing of finely dispersed ceramic powders in the form of a colloidal suspension, components based on a CAD model can be produced. In contrast to powder bed-based 3D printing, however, the ceramic powder is applied directly through nozzles and not held together by applying a binder to a powder bed. DIP, as an AM process, has the potential to produce a wide range of multi-material ceramic structures and shapes with high resolution. Due to the layered structure, undercuts and overhangs can be realized. However, supporting structures such as carbon, which can be removed after printing, must be used.
