Formulation of Photopolymer Resins for Use in 3D Printing Microfluidic Devices
Preterm birth leads to major complications in both the short- and long-term health of the child and is a leading cause of death among infants. We are developing a technique to use 3D-printed microfluidic devices to test for biomarkers related to preterm birth risk. Stereolithographic 3D printing is being used to make these devices to cut down cost and fabrication time. We are studying alternate resin formulas to be used in the 3D printing of these devices with emphasis on the monomers methyl methacrylate and vinylpyrrolidone. In the initial phase of the experiment photoinitiators and UV absorbers were tested for solubility by adding a measured to a vial and then adding in sequence a fixed volume of the monomer. The next phase will be to create simple resins which will be photopolymerized to test for polymerization compatibility with the 3D printer. From this experiment, many possible UV absorbers and photoinitiators were identified that can be used as a basis for new 3D printing formulations.
