Influence of Spectral Bandwidth on the Working Curve in Vat Photopolymerization. [PDF]

Addit Manuf
In vat photopolymerization, 3-dimensional parts are fabricated by using patterned light to spatially cure a liquid resin. One of the foundational measurements for vat photopolymerization is known as the working curve whereby the depth (i.e. thickness) of cured resin is measured as a function of radiant exposure.

Feasibility and Limitations of the Advanced Replica Process for Bioactive Glasses

Advanced Engineering Materials, EarlyView.
Periodic 3D‐printed Kelvin‐cell templates enable a controlled advanced replica process for fabricating highly porous glass lattices. Across P45K9, 45S5, and 13–93, material‐dependent differences in coating, burnout, and shrinkage lead to distinct strut morphologies, while comparable final porosities of 83%–88% are retained.

Fabrication of Microgel-Reinforced Hydrogels via Vat Photopolymerization. [PDF]

ACS Macro Lett
We report a facile method for the vat photopolymerization (i.e., digital light processing, DLP) of microgel-reinforced hydrogels that leverages both light and dark polymerization for curing. As an example, norbornene modified hyaluronic acid (NorHA) microgels at varying volume fractions swollen in acrylamide monomer are implemented as resins.
