Additive Manufacturing of Metallic and Ceramic Components

Additive Manufacturing of Metallic and Ceramic Components

Use of Material Extrusion, Especially the Use of Filaments for Sintering Processes
Christian Kukla, Stephan Schuschnigg, Clemens Holzer
The filament printing presented here can be used to produce metallic and ceramic components with complex shapes. Filaments in various highly filled polymers are available for the process. By means of the Shaping-Debinding-Sintering process the green bodies are converted into metallic/ceramic components. As with the PIM process, the filament printing can be used to produce near-net-shape parts, whereby the sintered bodies have a linear shrinkage of 15-20 % compared to the green bodies. In order to produce parts of very high quality, the printing process must be controlled accordingly.

Direct Inkjet Printing

Direct Inkjet Printing

A versatile manufacturing technology for individually designed functional components
Anja M. Wätjen, Michael Kramer, Philipp Gingter, Rainer Telle
Direct Inkjet Printing enables computer-aided additive manufacturing of three-dimensional objects, broadening its office applications. The conventional ink in the cartridge is replaced by a suspension, containing particles of the desired material. By successive printing of cross-sections, the 3D-sample is built up layer by layer. Complex geometries and individually designed objects are printed through this tool-free technology. Direct Inkjet Printing of ceramic suspensions by a thermal printhead allows for the production of parts in a variety of application fields, like microelectronics or medicine, where complex functional components are required.
