description The utility model discloses a liquid rocket engine nozzle structure suitable for 3D printing, each nozzle is provided with a tangential hole, a supporting cavity used for placing a supporting column is arranged between two adjacent nozzles, each supporting cavity comprises an upper cavity section and a lower cavity section, the upper cavity section is located above the lower cavity section, the aperture of the upper cavity section is smaller than that of the lower cavity section, and the upper cavity section is located above the lower cavity section. The tangential hole is formed in the side wall of the lower cavity section; when the supporting column is placed in the supporting cavity, an avoiding space is formed between the outer side surface of the supporting column and the hole wall of the lower cavity section. The hole diameter of the upper cavity section is set to be smaller than that of the lower cavity section, and during 3D printing, a supporting column placed in the supporting cavity can be in direc
