Declarations under Rule 4.17: — of inventorship (Rule 4.17(iv)) Published: — with international search report (Art. 21(3)) (54) Title: A RESIN FORMULATION AND USES THEREOF (57) : 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.
