description The invention discloses an on-orbit 3D printing reflector antenna which comprises a main reflector and a feed source assembly. The generatrix of the main reflecting surface is a parabola, in-orbit 3D printing forming is carried out, 3D printing is started from the center of the main reflecting surface, circle-by-circle operation is carried out in a spiral winding mode, the outer side of the inner-circle spiral line in the adjacent spiral lines is embedded into the inner side of the outer-circle spiral line and fused into a whole, a paraboloid is formed after all the spiral lines are printed, and the paraboloid is the inner concave face of the main reflecting surface. Meanwhile, the working surface of the main reflecting surface plays a main radiation role; the feed source assembly is mounted on a mounting plate of an on-orbit satellite, on the on-orbit satellite or on the main reflecting surface through a supporting rod, the feed source assembly is positioned right above the center of the inner concave surfac
