SEM images of the lyophilized 3D printed samples at different magnifications, showing the interconnected porous cross-linked gel structure, (A) GelMA, (B) CNP (50%) GelMA, (C) CNP GelMA, (D) CNP + GelMA, EDS mapping for CNP GelMA (E-1) Ca, (E2) P; CNP + GelMA (F-1) Ca, (F-2) P. For crosslinking of solutions, continuous UV irradiation was given to the 40%(w/v) polymer solutions in DI water with Igacure 2955 (5%, w/w)
