Integrated biomaterial scaffold with 3d printed lattice backbone

Abstract

A bone graft scaffold including the combination of a lattice structure having a triply periodic minimal surface (TPMS) shape and a cryogel solution disposed within the lattice structure. Also described is a method of making an integrated bone graft scaffold by freezing a cryogel solution, pouring the cryogel solution onto a scaffold, and freezing the cryogel solution poured onto the lattice structure to form an integrated bone graft scaffold. The cryogel solution may be a chitosan-gelatin cryogel and the lattice structure may be a 3D printed gyroid lattice structure.
