Cryogel has macroporous structure and advantages of mechanical stability and injectability for biomedical applications. Three-dimensional (3D) printing is a customized manufacturing technology. However, there is little research on 3D printing of cryogel. In this work, we developed a 3D-printable chitosan cryogel using difunctional polyurethane nanoparticles as the crosslinker that reacted with chitosan at 4 °C for 4 h to form a stable feeding hydrogel (pre-cryogel) for 3D printing. The printed pre-cryogel was frozen at -2
