Study of Graphene Oxide-based 3D Printable Composites as Potential Ink for Vat Polymerization Digital Light Processing

Abstract

VAT polymerization is a 3D printing technology that use photopolymerization to create 3D objects. A liquid polymer resin is exposed to ultraviolet (UV) radiation to convert it into a solid. The concentration of GO plays a critical function in controlling solution viscosity, agglomeration and hence 3D printing efficiency. At lower concentrations of GO dispersion, the system's liquid-like behaviour renders 3D printing impossible to implement. Higher concentrations of GO exhibit gel behaviour with a high elastic modulus. Our aim is to determine the optimum concentration of Graphene oxide (GO) at range 10-25 mg in photopolymer resin (PUA) for Vat Photopolymerization Digital Light Processing.
