Abstract

A photoinitiated polymerizable composition for 3D printing, the polymerizable composition comprising a nanogel component that comprises nanogel particles, wherein the nanogel particles comprise a copolymer with polymerizable reactive groups suitable for reacting with each other or a reactive diluent monomer, a reactive oligomer, a resin, or a combination thereof that is present in the polymerizable composition upon photoinitiation, wherein the nanogel component has a glass transition temperature that is in a range of about −50 C and about 20 C and an average molecular weight that is in a range of about 10 kg/mol and about 100 kg/mol, and wherein the nanoparticles have an average hydrodynamic radius that is in a range of 1 nm to about 5 nm.
