3D printing of transparent spinel ceramics with transmittance approaching the theoretical limit

3D printing of transparent ceramics has attracted great attention recently but faces the challenges of low transparency and low printing resolution. Herein, magnesium aluminate spinel transparent ceramics with transmittance reaching 97% of the theoretical limit have been successfully fabricated by s...

Various transparent spinel lenses and microlattices have been printed at a high resolution of ~100-200 µm. The 3D printed spinel lens has demonstrated fairly good optical imaging ability and the printed Diamond microlattices as a transparent photocatalyst support for TiO2 have significantly enhanced its photocatalytic efficiency compared with opaque counterparts.
