Effect of Printing Parameters on the 3D Printing Molding Effect of Unrinsed Sturgeon Surimi Gel

Abstract

In order to further improve the printing quality of unwashed sturgeon surimi gel, this paper explored the influence of printing parameters such as printing speed, layering height, filling density, nozzle diameter, extrusion degree and temperature on the 3D printing effect of surimi gel, and evaluated the printing accuracy. The results showed that the layering height should be the same as or slightly lower than the nozzle diameter, and the higher the layering height, nozzle diameter and printing speed were, the higher the printing efficiency was. Based on the comprehensive printing effect and printing efficiency, the optimal printing parameters were determined as nozzle diameter 1.20 mm, layering height 1.2 mm, filling density 100%, extrusion degree 100%, printing speed 25 mm/s and temperature 25 °C. Under these printing parameters, the structure of the printed surimi was tight, and the formability was good and the printing accuracy was high, which could obtain high-quality 3D printing surimi.
