With additive manufacturing (AM) on the rise in industrial production, different industries are looking for a way to benefit from the advantages over conventional manufacturing methods like milling or casting. The layer by layer approach allows the parallel construction of different complex structures with simultaneous customization of the parts, while waste material is significantly reduced. This is especially interesting for the processing of advanced ceramic materials, where often customized and single parts are required. Regarding ceramics, Lithographic Ceramic Manufacturing (LCM) provides the highest surface quality and achievable precision compared to any other AM technologies, which is necessary to meet the high demands from dental industry regarding accuracy and reproducibility. At TU Wien, we achieved expertise in printing different kinds of ceramics and glasses by using specially developed stereolithography printers based on digital light processing (DLP) followed by a thermal debinding and sintering processes. In dental industry, glass ceramic materials are widely used for customized and aesthetic restorations. This work deals with the processing of lithium disilicate via an AM technology, offering highly dense (>99%), full ceramic parts which meet the requirements for the use as dental restorations. With outstanding mechanical properties of over 400 MPa flexural strength, excellent translucency and accuracy, veneers, crowns and even bridges, especially for the anterior tooth area can be reproducibly printed, debinded and sintered.

随着工业生产中增材制造（AM）的兴起，不同行业正在寻找一种方法，以从传统的制造方法（如铣削或铸造）中受益。逐层方法允许并行构造不同的复杂结构，同时定制零件，同时显着减少了废料。对于需要经常定制和单个零件的高级陶瓷材料的加工而言，这尤其有趣。关于陶瓷，与任何其他增材制造技术相比，光刻陶瓷制造（LCM）可提供最高的表面质量和可达到的精度，这对于满足牙科行业对准确性和可重复性的高要求是必需的。在维也纳工业大学 我们使用专门开发的基于数字光处理（DLP）的立体平版印刷机，然后进行热脱脂和烧结工艺，在印刷各种陶瓷和玻璃方面获得了专业知识。在牙科行业，玻璃陶瓷材料被广泛用于定制和美学修复。这项工作通过AM技术处理二硅酸锂，可提供高密度（> 99％）的全陶瓷零件，满足用作牙修复体的要求。凭借出色的机械性能（超过400 MPa的抗弯强度），出色的半透明性和准确性，可重复印刷，脱胶和烧结，特别是针对前牙区域的贴面，牙冠甚至牙桥。
