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.
