Beschreibung
Zusammenfassung:	The invention discloses a novel 3D printer nozzle structure. The novel 3D printer nozzle structure comprises a first fixed piece, a motor base, a motor, a gear, an injection molding pressing piece, a second fixed piece, a throat pipe, a heating block, a nozzle, a heating rod and a temperature sensing probe; the heating rod, the temperature sensing probe and the heating block are integrally molded; and multiple leads are leaded out from the surface of the heating block, and are respectively connected with the heating rod and the temperature sensing probe. In the nozzle structure provided by the invention, the heating rod, the temperature sensing probe and the heating block are integrally molded, so that the compactness is good; no gap is formed between the heating rod and the heating block, so that the heating is fast; no form is formed between the temperature sensing probe and the heating block, so that the induction sensitivity is high, the temperature of the heating block can be precisely detected, and the
