Dual-cure epoxy resins for 3d printing of high-performance materials

A formulation comprising a dual-cure material being in a form of a monomer or an oligomer, and a multifunctional curing agent, for use in a method of additive manufacturing, wherein the formulation optionally comprises an ink carrier or a carrier suitable for printing.

The formulation according to claim 1, wherein the dual-cure material is of general structure (II):

• wherein G is a carbon group comprising between 2 and 50 carbon atoms, and optionally comprising one or more ring structures selected from 4-, 5- and 6-membered carbocyclic, aromatic or heteroaromatic ring systems.

A process for forming a 3D object or pattern, the process comprising inducing polymerization of at least one dual-cure material in presence of a multifunctional curing agent and a photoinitiator, to form a crosslinked polymer structure or pattern, wherein the induction of polymerization comprises irradiation of the at least one dual-cure material in presence of the multifunctional curing agent and the photoinitiator by visible or UV or NIR or IR radiation.
