PROTEIN-BASED RESINS FOR ADDITIVE MANUFACTURING
Methods of fabricating 3D printed structures from biocompatible proteins include forming a photoreactive, proteinaceous resin, and 3D printing biocompatible structures from the resin by the patterned application of light in a select wavelength to cure the resin into the desired structures. Suitable photoreactive proteinaceous resins can be formed by reacting an aqueous solution of an acrylated or methacrylated globular protein with a photoreactive comonomer or photoinitiator. Structures printed from the photoreactive, proteinaceous resin can be photo-cured and dried to form bioplastic structures.
