Zusammenfassung: | The invention belongs to the technical field of metal part forming, and discloses a 3D printer with a compound heating function and a 3D printing method. The 3D printer comprises a first heating mechanism and a second heating mechanism which are used for heating metal wires. The metal wires are heated by the first heating mechanism and the second heating mechanism in order. The first heating mechanism is an electromagnetic induction heating mechanism. The second heating mechanism is a laser device, an electron emitter or a plasma generator. According to the 3D printer with the compound heatingfunction and the 3D printing method, the metal wires are heated by utilizing an electromagnetic induction heat source firstly, and the effects of preheating and heat insulating are achieved, so thatthe temperature difference between the extruded metal wires and the non-extruded metal wires is small, and interlayer combining performance of the metal wires is improved; and then the metal wires arefurther heated by utilizin |
