Additive manufacturing processes become more and more important in almost all areas, also for medical implant application. Medical implants made of ceramics are known for their excellent biological compatibility. For increasing the ingrowth of cells into an implant, a function-optimized structure with a defined porosity seems to be advantageous. Additive manufacturing is suited to realize defined and filigree structures. Lithography-based ceramic manufacturing (LCM), for example, has a high resolution, but still a limited material portfolio. Alumina toughened zirconia is a very interesting material for medical applications, but not commercially available for LCM. In this study, the development of an ATZ suspension usable in the LCM process with a bulk material density higher than 99% after sintering is presented. Furthermore, printing of lattice test structures for the evaluation of accuracy in dependence of printing dimension is demonstrated.

增材制造工艺在几乎所有领域都变得越来越重要，对于医疗植入物应用也是如此。由陶瓷制成的医疗植入物以其出色的生物相容性而闻名。为了增加细胞向植入物中的向内生长，具有限定的孔隙率的功能优化的结构似乎是有利的。增材制造适合实现定义的和花丝结构。例如，基于光刻的陶瓷制造（LCM）具有高分辨率，但材料组合仍然有限。氧化铝增韧的氧化锆是一种非常有趣的材料，可用于医疗应用，但不适用于LCM。在这项研究中，提出了可在LCM工艺中使用的ATZ悬浮液的开发，其烧结后的松散材料密度高于99％。此外，
