The invention discloses an in-situ 3D printing device for special-shaped solid charging. The in-situ 3D printing device comprises a six-degree-of-freedom movement mechanical arm, a conveying pipe, a printing nozzle and a material pool. The printing nozzle comprises a temperature control material conveying cavity and an ultraviolet laser light source; the temperature control material conveying cavity is installed at the tail end of the six-degree-of-freedom motion mechanical arm, and the ultraviolet laser light source is installed on the outer side of the temperature control material conveying cavity. The invention further discloses a printing method. The printing method comprises the steps that the combustion chamber shell with the heat insulation layer is vertically fixed to a workbench; the materials in the material pool are conveyed into the temperature control material conveying cavity; the temperature control material conveying cavity is used for controlling the materials within a preset temperature rang
