Additive manufacturing technologies, compared to conventional shaping methods, offer great opportunities in design versatility, for the manufacturing of highly porous ceramic components. However, the application to glass powders, later subjected to viscous flow sintering, involves significant challenges, especially in shape retention and in the achievement of a substantial degree of translucency in the final products. The present paper disclosed the potential of glass recovered from liquid crystal displays (LCD) for the manufacturing of highly porous scaffolds by direct ink writing and masked stereolithography of fine powders mixed with suitable organic additives, and sintered at 950 °C, for 1–1.5 h, in air. The specific glass, featuring a relatively high transition temperature (Tg~700 °C), allowed for the complete burn-out of organics before viscous flow sintering could take place; in addition, translucency was favored by the successful removal of porosity in the struts and by the resistance of the used glass to crystallization.

Die additive Fertigung von Schneidstoffen hat das Potenzial, leistungsfähigere Zerspanungswerkzeuge zu ermöglichen. Das Lithography-based Ceramic-Manufacturing-(LCM)-Verfahren erlaubt die Fertigung hochbelastbarer Bauteile aus Keramik. Dieser Beitrag stellt zum einen das LCM-Verfahren und zum anderen die Entwicklung additiv herstellbarer Wendeschneidplatten vor. Zuletzt erfolgt die Überprüfung der Funktionstauglichkeit von additiv hergestellten keramischen Wendeschneidplatten in Außenlängsdrehversuchen mit vermicularem Gusseisen (GJV-450).   The additive manufacturing of cutting materials has the potential to enable more efficient cutting tools. The Lithography-based Ceramic Manufacturing (LCM) process allows for the production of high-performance ceramic components. This article presents the LCM process as well as the development of indexable inserts that can be produced additively. Finally, the results of external longitudinal turning tests in Compacted Graphite Iron (CGI-450) are presented.

Additive manufacturing (AM) and three-dimensional printing (3DP) technologies are being developed for use in manufacturing. In this study, a new AM technology, laser stereo-lithography, that enables to fabricate ceramic components in a single process is developed. This method is demonstrated with alumina under various laser conditions.

Titania and alumina photonic crystals were fabricated by using stereolithographic additive manufacturing to control electromagnetic waves in terahertz frequency. Micro ceramic patterns were designed spatially by graphic software. Photosensitive liquid resin with ceramic particles were spread onto a grass substrate by mechanical knife edge, and two dimensional (2D) images were drawn using fine pattern exposing to create a cross sectional solid layer. After stacking these layers, the obtained three dimensional (3D) structures of composite precursors are dewaxed and sintered.
