Tissue engineering scaffold is used to facilitate and support cell/tissue growth. Fabrication of silk fibroin scaffold using newly developed direct dissolution salt leaching method is successfully done. This method significantly reduces the processing time compared to the traditional method. Cells attachment, cells growth, cells migration, and diffusion of nutrients and waste are affected by the architecture scaffold. In this study, 3D analysis on porous architecture evaluation of direct dissolution salt leaching scaffolds is conducted. Scaffolds are fabricated from different NaCl particle sizes of 158, 250, 378, and 503 μm at 12% w/v silk fibroin concentration. Scaffold architecture is evaluated using microcomputed tomography (micro‐CT) method. Evaluation of scaffold architecture shows that the use of larger NaCl particle size increases the scaffold pore size. The relationship between scaffold pore size and scaffold porosity, scaffold wall thickness, pore interconnectivity, scaffold specific surface area is established, which is important for tissue formation.
