The present invention relates to a 3D printing device suitable for space heating based on sunlight, which solves the problem of the lack of precise temperature control system in existing 3D printing devices, and the inability of the system to fold, making it unsuitable for rocket transportation and extreme temperature environments in space. The device includes a fixed frame, a feeding system, a melter, a discharge device, a substrate, a three-dimensional motion platform, a spotlight, and an attitude adjustment system; The feeding system is set on a fixed frame to feed the printing material into the melter; The melter is set on a fixed frame for heating the printing material; The discharge device is set inside the melter to stack the heated printing material on the substrate; Connection between 3D motion platform and substrate; The spotlight is set on a fixed frame to focus sunlight and shine it onto the melter. The spotlight is a flexible and extendable folding spotlight, and the posture adjustment system is connected to the spotlight on the fixed frame. The fixed frame is equipped with a tracking sensor.
