Stereolithography has emerged as one of the most popular methods of 3D printing owing to its fast print speeds, high level of detail, and ability to print complex geometries, but it is regrettably constricted to mono-material production. Herein, a novel approach to multimaterial 3D printing using an otherwise monomaterial 3D printing technique is proposed using an emulsion resin. Stabilisation using various surfactants will be undertaken, and their effects on the final structure and mechanical properties will be investigated.
