In this paper, three different mass fractions of sodium carbonate were used for degumming to obtain different degrees of damaged silk fibroin fibers, which were then treated with formic acid to shrink and bond them into 3D scaffolds. The structure and performance of silk fibroin fibers and silk fibroin 3D scaffolds were characterized by scanning electron microscopy, infrared spectroscopy, X-ray diffraction, a differential thermal scanner, a universal materials testing machine, and laser confocal microscopy, and the degradation performance was tested by protease degradation. The results showed that an excessive mass fraction of sodium carbonate would cause partial hydrolysis of fibroin fibers, decrease the mechanical properties of fibroin fiber, increase the surface roughness of fibroin fibers, and make mouse embryonic fibroblasts easier to adhere and grow. Silk fibroin fibers were slightly dissolved, shrunk, and dispersed in formic acid. The mass fraction of sodium carbonate can adjust the enzymatic degradation rate of the silk fibroin 3D scaffolds. With the extension of the degradation time, minerals will be deposited on the surface of the scaffolds. The results show that the silk fibroin 3D scaffolds have biocompatibility, mechanical properties, and degradability, which provides a good material for a barrier biofilm in the future.

“…The poor tensile strength and elasticity of physical cross‐linking inks is due to the large size of the β‐sheets. This reason also causes the ink to behave in a milky white colour [139–140] . In addition, the β‐sheet crystals are stiffness‐maintaining and non‐stretchable.…”

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.

“…Silk fibroin, like wool keratin, is formed by the condensation of α-amino acids into polypeptide chains, but the long-chain molecules of silk fibroin are not linked together by disulfide bridges as they are in wool. Chemical treatments can cause modification of main peptide chains, and side chains of amino acids, which in turn influence the fiber's chemical, physical, and mechanical properties [8]. Silk fiber is easily damaged when dyeing at the boil, so lowtemperature dyeing is usualy preferred [7].…”
