The results showed that the toughening treatment roughened the surface of starch granules and increased the viscosity and pasting temperature of the starch. The toughened potato starch gel showed greater mechanical strength and a more stable and ordered internal structure than the native starch gel. It was found that toughening treatment for 36 h had a significant effect on the printing characteristics of potato starch gels, resulting in the highest printing accuracy and height as well as the best printing performance.
