Dapivirine + Pritelivir + Levonorgestrel 3D Printed IVR

Our paramount innovation is use of digital light synthesis – a novel 3D printing process known as continuous liquid interface production (CLIP™) – for rapid, scalable, and cost-effective manufacturing of geometrically and mechanically tunable, rationally designed intravaginal rings as platforms for multi-drug delivery.
