The invention discloses a Chuzhou chrysanthemum-rice flour 3D printing food material and a preparation method thereof, and specifically relates to the technical field of 3D food processing. The 3D printing food material consists of the following raw materials in parts by weight: 0.4-1.2 parts of Chuzhou chrysanthemum superfine powder, 82-90 parts of water, 4-12 parts of icing sugar, 20-30 parts ofbutter and 95-110 parts of rice flour. The used materials do not contain chemical additives, so the 3D printing food material is pollution-free and healthier; the 3D printing food material is prepared according to the preset proportion, and has the advantages of moderate viscosity, moisture and oil content, continuous discharging in the 3D printing process, good moulding and effective preventionof material plugging; according to the 3D printing food material, the Chuzhou chrysanthemum superfine powder is added to the rice flour, so food not only has excellent taste, but also has quite high nutritional value, and the nutrient elements in the two components complement each other, have synergistic effect, and are suitable for different people to eat.
