Combining Zirconia and Titanium Suboxides by Vat Photopolymerization [PDF]

Materials, 2021
A recently developed multi-ceramic additive manufacturing process (multi-CAMP) and an appropriate device offer a multi-material approach by vat photopolymerization (VPP) of multi-functionalized ceramic components. However, this process is limited to ceramic powders with a certain translucency for visible light.

Organocatalytic vat-ring-opening photopolymerization enables 3D printing of fully degradable polymers

Communications Chemistry, 2023
Vat-polymerization 3D printing (3DP) enables the high speed printing of precise and intricate 3D models, yet it inevitably produces highly crosslinked polymers that are not easily degradable or recyclable.

Continuous Vat Photopolymerization for Optical Lens Fabrication

Small, 2023
AbstractOptical lenses require feature resolution and surface roughness that are beyond most (3D) printing methods. A new continuous projection‐based vat photopolymerization process is reported that can directly shape polymer materials into optical lenses with microscale dimensional accuracy (< 14.7 µm) and nanoscale surface roughness (< 20 nm ...
