Development of Static Mixers for Millireactors and Their Production by Vat Photopolymerization [PDF]

Micromachines (Basel)
The addition of static mixers within reactors leads to higher productivity of a process and an additional increase in mass and energy transfer. In this study, we developed millireactors with static mixers using stereolithography, an additive manufacturing technology.

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.

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.

Results of an interlaboratory study on the working curve in vat photopolymerization. [PDF]

Addit Manuf
The working curve informs resin properties and print parameters for stereolithography, digital light processing, and other photopolymer additive manufacturing (PAM) technologies. First demonstrated in 1992, the working curve measurement of cure depth vs radiant exposure of light is now a foundational measurement in the field of PAM.
