Manufacturing Ceramics with Light

  • Additive manufacturing of extremely complex and filigree geometries from ceramic materials is a fascinating topic as ceramic materials are especially suitable for extremely small structures thanks to their physicochemical properties: they are chemically stable and do not corrode, while exhibiting unique mechanical properties especially in the micrometre range (Fig. 1). In addition, the ceramic structures made of yttria-stabilized zirconia (YSZ) shown in the figure are transparent, which makes them interesting candidates for the development of miniaturized optical components. The refractive index of YSZ measures 2,2 and is therefore considerably higher than that of polymer-based materials or glasses. The possibility of building this type of structure is enabled with the use of ceramic slurries with sufficiently high Transparency for the volumetric process of two-photon polymerization, which uses a femtosecond-short-pulse laser to structure photo-crosslinkable resins in the volume of oneAdditive manufacturing of extremely complex and filigree geometries from ceramic materials is a fascinating topic as ceramic materials are especially suitable for extremely small structures thanks to their physicochemical properties: they are chemically stable and do not corrode, while exhibiting unique mechanical properties especially in the micrometre range (Fig. 1).

The possibility of building this type of structure is enabled with the use of ceramic slurries with sufficiently high Transparency for the volumetric process of two-photon polymerization, which uses a femtosecond-short-pulse laser to structure photo-crosslinkable resins in the volume of one droplet. Slurries with even further optimized transparency allow even the application of xolography, a volumetric process that builds components with relatively low resolution, but in relatively large volumes and higher productivity. In the scope of the research presented here, for the first time, this process is applied to sintered ceramic materials. To be able to use minute ceramic structures as real components, an approach for the hybridization of processes ispresented in which components in the centimetre range, with relatively low resolution, are combined with very high-resolution nanostructures.zeige mehrzeige weniger
