Nanofillers in vat photopolymerisation additive manufacturing: mechanical properties of graphene and acrylate-based composites
摘要
Additive Manufacturing (AM), also known as three-dimensional (3D) printing, is a fabrication technology with great potential for rapid prototyping and mass production. AM polymer resin does not exhibit remarkable mechanical properties because it has limited strength, such as brittleness and poor impact resistance. Vat Photopolymerisation (VP) is a part of AM and has been recognised as a crucial technology in the fabrication industries with intricate shapes and modified mechanical properties. Graphene and its derivatives have significant commercial potential that can be improved and designed for specific uses by selecting suitable fillers and processing conditions in AM. This review studies the optimisation concentration of graphene which helps enhance the mechanical properties of the tensile strength, flexural strength, and Young’s modulus of the 3D printed product. Future research prioritising the concentration of graphene to enhance the mechanical properties of these composites for a wide range of applications in AM is also discussed in this review article.
