“…Since tyrosine is discovered in SF as a constituent amino acid at about 10 wt % (~5 % mol), tyrosinase is the first enzyme proposed as a self-cross-linking agent for this protein. [202][203][204][205][206][207][208][209][210][211][212][213][214] Tyrosinase is a dual catalytic enzyme. It exhibits both hydroxylase activity and oxidase activity, catalyzes forming quinones from monophenols and diphenols, and can further react with hydroxyl or amine groups.…”

Due to excellent biocompatibility, sufficient raw material, robust mechanical properties and easy cross‐linking, Silk Fibroin (SF) is a promising protein for 3D printing inks and an ideal candidate for 3D scaffolds in fields like regenerative medicine, bioelectronics and bio‐optics. In order to meet the requirements of print accuracy, mechanical properties and form retention capabilities, the first step is to prepare SF 3D printing inks using physical, chemical or other strategies of cross‐linking. The basic chemical groups and physical structure of SF determines its ability to form 3D networks under different conditions using various cross‐linking strategies. In the preparation of SF‐based 3D printing inks, physical, chemical or other strategies of cross‐linking improve the qualities of printing, but each strategy has its advantages and disadvantages. This paper discusses different crosslinking strategies for SF to support the development of exciting potential for SF‐based 3D printing inks to meet more needs in the future.
