A Study of the Gelatin Low-Temperature Deposition Manufacturing Forming Process Based on Fluid Numerical Simulation

Low-temperature deposition manufacturing has attracted much attention as a novel printing method, bringing new opportunities and directions for the development of biological 3D complex-shaped food printing. In this article, we investigated rheological properties gelatin solution conducted numerical simulation experimental research on low-temperature extrusion process solution. The velocity, local shear rate, viscosity, pressure distribution material in were calculated using Comsol software. effects initial temperature, inlet print head diameter flow field quality explored. results show that: (1) fluidity mechanical vary with its concentration; (2) temperature material, all have varying degrees influence field; (3) concentration change mainly affects channel; (4) greater velocity rate higher outlet section; (5) gel, lower viscosity field. This article is great reference value colloidal materials that are difficult to form at room temperature.
