The invention discloses a preparation method of a minced meat material for 3D printing. The method includes: using livestock and poultry meat as the main raw material, and performing raw material preprocessing, tenderization, meat mincing and minced meat making to obtain the minced meat material for 3D printing. The preparation method has the advantages that the minced meat gel system for 3D printing is significant to the development of minced meat 3D printing; starch is added into minced meat, so that the gel strength and elasticity of minced meat gel can be increased while minced meat viscosity can be lowered, and the prepared minced meat material is moderate in viscosity, good in flowability, fine and smooth in pulp, less prone to 3D printer blocking, timely in discharge, high in printing precision, high in three-dimensional forming rate, capable of achieving diversification of creative production, capable of producing high-precision and unique-style 3D printing minced meat products, capable of completely getting rid of mould constraint and capable of satisfying people's personalization requirements on food.
