Vat Photopolymerization Additive Manufacturing of Functionally Graded Materials: A Review

Functionally Graded Materials (FGMs) offer discrete or continuously changing properties/compositions over the volume of parts. The widespread application FGMs was not rapid enough in past due to limitations manufacturing methods. Significant developments technologies especially Additive Manufacturing (AM) enable us nowadays manufacture materials with specified changes volume/surface components. use AM methods for may allow compensate some drawbacks conventional and produce complex near-net-shaped structures better control gradients a cost-efficient way. Vat Photopolymerization (VP), type method that works according principle curing liquid photopolymer resin layer-by-layer, has gained recent years high importance its advantages such as low cost, surface quality control, no need support structures, limitation material. This article reviews state-of-art future potential using VP FGM manufacturing. It concluded improvements printer hardware setup software, design aspects printing methodologies will accelerate
