Method & Evidence

AimCan epoxidized soybean oil acrylate be used to 3D print smart, biocompatible scaffolds with shape-memory properties for biomedical applications?

MethodExperimental research and material characterization.

ProcedureA novel soybean oil epoxidized acrylate resin was synthesized and then solidified into scaffolds using 3D stereolithography. The effects of laser frequency and printing speed on scaffold structure were investigated. Shape memory behavior was tested by deforming scaffolds at low temperatures and observing recovery at body temperature. Biocompatibility was assessed by culturing human bone marrow mesenchymal stem cells (hMSCs) on the scaffolds and comparing adhesion and proliferation rates with traditional biomaterials (PEGDA, PLA, PCL).
