LSD based additive manufacturing of ceramics
- The production of ceramic parts by an additive manufacturing process is still a challenging task. Especially in powder-based technologies, such as 3D printing or laser sintering, the feedstock material is commonly spread out as thin layers of a dry powder/granulate by a roller or a shaker system. As consequence the layers are characterized mostly by a low packing rate. On the other hand, from a ceramic processing viewpoint, appreciable densities can be achieved by the use of ceramic slurries. In this context, the so-called Layer-wise Slurry Deposition (LSD) process has been developed. An overview about the LSD process and latest advances in the development of this technology will be presented.
