The invention discloses a vegetable cake raw material for 3D (three-dimensional) printing and belongs to the technical field of preparation of vegetable cake raw materials. The vegetable cake raw material comprises flour, eggs, carrots, soybean lecithin, powdered milk, butter, flexibilizer, elasticizer, lubricant, cosolvent, flatting agent, dispersant, compatilizer, emulsifier, stabilizer, antioxidant, coagulant aid, antibacterial agent, flavor enhancer, flavoring agent and sweetening agent. By the vegetable cake raw material, heating rate, melting temperature of models and stereo-shaping rate during printing can be increased; the vegetable cake raw material has stable flowability, certain viscosity and stable shaping temperature value, is good in heat resistance, and cannot cause hole blockage during printing; the vegetable cake raw material can be made into vegetable cake products, which retain original characteristics and taste of vegetable cake and are novel and attractive in appearance, through the 3D printing technique.
