Processo basato su litografia per la produzione di ceramiche trasparenti e ceramiche trasparenti cosė ottenute

The present invention describes an innovative process for the production of ceramic-based transparent materials with a variable 3-dimensional composition and complex shapes. The invention relates to three-dimensional (3D) printing, and more particularly to SLA, stereolithography by digital lighting processing), to generate structured polycrystalline Y3Al5O12 (YAG)-based transparent ceramics, undoped and variably doped with rare earth ions and transition metal ions in tailored spatial configurations and complex shapes, for multiple uses, including laser gain media, scintillators and phosphors.

1. Easier fabrication of parts with a tailored inner structure in terms of variation of composition/doping within the material 2. Near-net shape process, with reduced manufacturing scrap and post-processing. 3. Overcoming of inefficiency and limitations of the conventional fabrication processes of transparent ceramic YAG materials. 4. Small series manufacturing, parts available on demand, customization to suit a particular application or task. 5. In the case of lasers, the engineering of transparent ceramic YAG laser materials with controlled composition and / or doping at the microscopic level, made possible by the invention, will allow to control and reduce the thermo-mechanical stresses and parasitic emission that at high power densities limit the laser emission, opening the way to the development of innovative high power lasers. 6. Ability to quickly incorporate into the CAD data the suggestions related to the component design arising from the performances simulation models. 7. The feasibility of transparent ceramic YAG components with levels of design complexity not achievable with the processes currently in use will boost the development of further innovative applications of the same. 8. Ability to fabricate complex shapes and solid/void geometries, for instance light ducts or (to convey the pump radiation in laser devices, or to transport the material emission to a detector in scintillator applications) or cooling fluid ducts 9. The process is cost- and energy-saving compared to current ones.
