| description | The invention provides a 3D printing device and a 3D printing method, relates to the technical field of 3D printing, and aims to improve the bonding strength between layers of a component. The 3D printing device comprises a 3D printing control, a printing platform, a controller, a powder laying part and a heat source part. A printing nozzle is arranged at the bottom end of the 3D printing control, the heat source component is arranged on the plane, relative to the printing platform direction, of the printing nozzle, and the energy component moves along with movement of the 3D printing control. The controller is connected with the powder laying part, the 3D printing control part and the heat source part, and the controller controls a heat source unit at the corresponding position of the heat source part to generate a laser heat source after each layer of powder is laid on the printing platform; and a printing nozzle of the 3D printing control is controlled to extrude a layer of fiber prepreg wires to the print |
