Jet Assisted Wet Spinning of Photopolymerizable Material

Princeton Docket # 22-3931-1

Jet Assisted Wet Spinning (JAWS), an innovative fiber manufacturing technology developed by Princeton University researchers, offers unparalleled control and versatility in producing photopolymerized fibers. The process enables precise diameter tuning, allowing for the creation of fibers ranging from hundreds of microns down to less than 10 microns, providing exceptional flexibility for diverse applications. This unique photopolymerization method eliminates common clogging issues and is a major improvement when compared to similar fiber production methods such as electrospinning apparatuses. JAWS is also designed for easy scalability; multiple precursor jets can be integrated without the need for significant additional equipment, facilitating cost-effective scaling of production capacity. The technology also allows for the customization of fiber shapes, including dumbbell, looped, and hollow configurations, which expands the potential applications of the resulting materials. Importantly, JAWS is fully biocompatible, making it ideal for biomedical and tissue engineering applications. JAWS-produced fibers are suitable for a wide range of industries, including cell culture materials, advanced textiles, optical devices, and biomedical engineering.
