Provided is a hybrid hydrogel composition and methods for its preparation and use in 3D printing biomaterials for tissue engineering applications. The hybrid hydrogel composition comprises discrete hydrogel particles of a first crosslinked polymeric network, interpenetrated- through and threaded by a second crosslinked polymeric network, dispersed in a medium. The first polymer is a thermo-responsive polymer, while the second is a protein-based thermo¬ denaturing polymer. The process for preparing this composition involves mixing swelled hydrogel nanoparticles of the first polymer with a non-crosslinked hydrogel of the second polymer in the presence of a crosslinking agent for the first polymer. The 3D printing method utilizes this composition below the LCST of the thermo-responsive polymer, followed by temperature increase wherein the second polymer cures and fixes the printed ink. This approach enables the creation of high-resolution structures, including artificial tissues with capillary blood vessels, featuring dimensions less than 50 μm.
