Photocurable compositions comprising 20-90% by weight of a polymerizable core resin; 20-90% by weight of a diluent resin miscible with said core resin; and at least about 1% by weight of at least one rheology modifier which is distinct from said diluent resin. Rheology modifiers of the present disclosure include compounds which may form covalent bonds with the core resin or diluent resin and compounds which have a particle size of 1-200 nm. Rheology modifiers which may form covalent bonds have at least one terminal functional group selected from the group consisting of acrylates, methacrylates, epoxides, oxetanes, nitriles, alkenes and alkynes.

Photocurable compositions having variable viscosities

This invention relates to a resin composition comprising at least one of a first monomeric or oligomeric component (A), at least one of a second monomeric or oligomeric component (B) and a photoinitiator. This invention also relates to a method of preparing a polymer from the resin composition, a polymer prepared from the resin composition, a method of forming a 3-dimensional printed article, and a kit comprising at least one of a first monomeric or oligomeric component (A), at least one of a second monomeric or oligomeric component (B) and a photoinitiator.

3D printable resin compositions

There is provided a resin formulation comprising a base acrylate monomer or oligomer, a solubilizing acrylate monomer or oligomer, a photoinitiator compound, a photoabsorber compound, and a photochromic dye, wherein the solubilizing acrylate monomer or oligomer comprises a functional group selected from the group consisting of hydroxyl, alkoxyl, carboxylic acid, amine, alkylamine, amide, alkylamide, alkylacrylate, acrylate, alkyl and heterocycloalkyl. There is also provided a method of preparing the resin formulation and uses of the resin formulation thereof.
