The invention belongs to the technical field of sand mold 3D printing equipment, and particularly relates to a sand mold manufacturing laser 3D printing platform with heating type sand boxes. The sand mold manufacturing laser 3D printing platform is characterized by comprising a base, stand columns arranged around the base, a suspension frame arranged on the tops of the stand columns, a lifting system arranged on the base, a displacement system arranged above the lifting system, a sand paving platform arranged on the displacement system, the heating type sand boxes surrounding the sand paving platform and located at the upper portion of a printing area, and collecting boxes arranged on side plates of the heating type sand boxes, and the tops of the heating type sand boxes are fixedly connected with the suspension frame through bolts. Rapidness and convenience are achieved through sand mold technology checking and technology correcting, and the sand mold manufacturing laser 3D printing platform is stable in structure and high in transmission efficiency. The printing platform can move up and down, each heating type sand box is formed by four heating plates in a defining manner, it is ensured that a sand mold printing layer is heated and solidified, accordingly, it is ensured that sand materials on the sand paving platform are constant in temperature, the temperature loss is low, and the sand material bonding quality and solidification rate are improved.
