Abstract: There is provided a resin formulation comprising a resin precursor, a crosslinking additive, a photoinitiator, and at least one luminescent dye, wherein the crosslinking additive comprises a functional group selected from the group consisting of hydroxyl, alkoxyl, carboxylic acid, amine, amide, alkylacrylate, acrylate, epoxy, alkyl and heterocycloalkyl. The crosslinking additive of the resin formulation may help to homogeneously disperse the luminescent dye in the resin formulation and decrease the viscosity by improving the miscibility and polarity between the resin precursor and the luminescent dye, leading to an increase of solidification rate of the resin formulation during 3D printing such as stereolithography and digital light processing (DLP). There is also provided a method of preparing the resin formulation and uses of the resin formulation thereof.

Abstract: There is provided a polymer composition comprising at least one (meth)acrylate monomer or oligomer, a phase separating agent, a photoinitiator and a photosensitizer. There is also provided a method of preparing a polymer resin comprising the step of polymerizing a solution of at least one (meth)acrylate polymer or oligomer, a photoinitiator, a photosensitizer and a phase separating agent in the presence of UV light to form the polymer resin. There is also provided a polymer resin and uses of the polymer composition.

Abstract: A method fabricates a transparent polymer plate or film. The method incudes applying an acrylate ink to a transparent substrate and illuminating the polymeric substrate and the acrylate ink with a light source to cause photopolymerization. The photopolymerization creates micro-louvre structures inside the transparent polymeric plate or film.
