Stealth pattern 3D printing method for surface of curved-surface composite material antenna housing

The invention provides a stealth pattern 3D printing method for the surface of a curved-surface composite material antenna housing. The stealth pattern 3D printing method comprises the steps that a mold is pretreated; a transfer film is sprayed on the mold according to preset parameters, the transfer film is a Metal-P metallized transfer film, the ratio of a diluent is 1: 1.2-1.5, and the viscosity of a transfer film solution is 15 s +/-2 s; a stealth pattern is printed on the transfer film in a 3D mode; paving a material on the invisible pattern and curing the material; and the formed antenna housing is demolded, so that the invisible pattern on the mold is transferred to the surface of the composite material antenna housing skin. The method can be used for transfer forming of a 3D printing pattern on the surface of the curved-surface composite material radome, the negative effects of insufficient surface smoothness of a composite material and poor line precision of the printing pattern are avoided, the invi
