In this study, polyetherimide(PEI)-based photocurable resin is prepared for applying DLP stereolithography process. The PEI resin is synthesized via condensation reaction between dianhydrides and diamino acids. In addition, glycidil functional groups are introduced into the PEI main chains for photochemical reaction. To prepare the photocurable resin for the stereolithography 3D printing process, the PEI resins are mixed with reactive diluents and photo initiators. By adjusting light dosage and compositions of the reactants, the photocuring reaction of the resin can be precisely controlled in the DLP stereolithography process. The photocurable resins and the printed specimens are characterized by using UTM, DSC, TGA, FT-IR and H1-NMR spectroscopy. In addition, biocompatibility of the PEI based resins is investigated by conducting cell culture experiments.
