Unique Short Title: "Biobased Photocurable Polyesters for Tunable Drug-Release Implants via DLP 3D Printing" Rewritten Abstract: This study presents the design and synthesis of novel biobased acrylate-functional polyester resins tailored for pharmaceutical-grade digital light processing (DLP) 3D printing. Using a sustainable synthesis route, fossil-based monomers were systematically replaced with renewable alternatives—including sebacic acid, succinic acid, 1,3-propanediol, isosorbide, and itaconic acid—to produce resins with tunable viscosity, curing kinetics, and network properties essential for drug-eluting implant fabrication. Photocurable formulations were optimized for vat photopolymerization, enabling high-resolution printing of complex geometries with controlled mechanical and thermomechanical performance. The biobased resins exhibited adjustable glass transition temperatures and storage moduli, supporting their application in customizable, implantable drug delivery systems. These materials offer a sustainable platform for the additive manufacturing of personalized medical devices with embedded pharmaceutical functionality, merging green chemistry with advanced pharmaceutical manufacturing.
