dc.description.abstract
Additive manufacturing technologies enable the production of parts with highly complex geometries, which has not been possible with conventional methods. In combination with modern software it is a big chance to use such capabilities for individual applications like in biomedical engineering. Lithography-based Additive Manufacturing offers the possibility to produce such high quality parts which is needed in those fields of application. The method uses a light source, for example a laser, or powerful light emitting diode (LED) to cure and structure a photosensitive material which can be filled with ceramic powder. In the case of ceramics the method is called Lithographic Ceramic Manufacturing (LCM) and has developed to a serious alternative to traditional manufacturing methods.
It is possible to structure different ceramics like alumina, zirconia or tricalcium phosphate with a solid loading of up to more than 50 vol.%, leading to high viscosities of the utilized ceramic slurries. We conducted a variety of rigorous tests to ensure that the mechanical properties, as well as the density of the new ceramic material was comparable to conventionally produced ceramic parts.
This study compares the fitting of stereolithographic structured parts to the original digital file. We demonstrate an improvement of the whole process chain beginning with support structures that obtain optimal building conditions and at the same time reduces the sinter distortion. Moreover we attempted to reduce the influence of z-overexposing and to find the optimal shrinkage parameters. As a result a resolution up to 25µm in all spatial directions was achieved. This study demonstrates the possibilities of structuring ceramic slurries using LCM and attempt to address the current difficulties in their handling.
