Hybridizing Lithography-Based Ceramic Additive Manufacturing with Two-Photon-Polymerization

Stereolithography processes such as lithography-based ceramic manufacturing (LCM) are technologies that can produce centimeter-sized structures in a reasonable time frame. However, for some parts specifications, they lack resolution. Two-photon-polymerization (2PP) ensures the highest geometric accuracy additive so far. Nevertheless, building up sizes large few millimeters or even centimeters is time-consuming process, which makes production of 2PP printed very costly. Regarding feedstock specification, requirements different to those LCM, and generally, feedstocks designed meet only one these technologies. In an attempt fabricate highly precise components rather size, it necessary develop suits both light-based technologies, taking advantage LCM’s higher productivity 2PP’s accuracy. Hybridization should bring desired precision region interest on reasonably without escalating printing costs. this study, specimens gained from transparent with yttria stabilized zirconia (YSZ) particles 5 nm at 70 wt% were presented. The resin was originally suit 2PP, while being also printable LCM. This work demonstrates how hybrid be sintered into full YSZ ceramics.
