The method comprises the following steps that a meat steak section picture is obtained; generating printing distribution points on a transverse section according to the steak section picture, wherein the printing distribution points comprise muscle printing points and fat meat printing points; generating the printing length of each muscle and fat meat fiber in the longitudinal direction according to the printing requirement; determining a printing starting coordinate and a printing ending coordinate of each fiber according to the printing distribution point and the printing length of each fiber, wherein the starting coordinate and the printing ending coordinate are three-dimensional coordinates; generating a printing file according to the printing starting coordinate and the printing ending coordinate of each fiber; and performing steak printing according to the printing file. According to the scheme, meat veins can be simulated according to pictures, and the fat degree can be set according to needs.
