The present invention relates to a 3D printer printhead. The 3D printer printhead comprises: an extrusion box, having a mounting cavity, a chip removal port communicated with the mounting cavity, and an air inlet communicated with the mounting cavity; an extrusion mechanism, provided in the mounting cavity, the extrusion box further having a feed end and a discharge end communicated with the feed end, the extrusion mechanism being arranged between the feed end and the discharge end; and a first heat dissipation mechanism, provided at the side of the extrusion box having the air inlet, an airflow generated by the first heat dissipation mechanism being capable of flowing into the mounting cavity through the air inlet and flowing out of the mounting cavity through the chip removal port. According to the 3D printer printhead provided by the present invention, while a printing operation is satisfied, heat dissipation requirements are satisfied by means of the airflow generated by the first heat dissipation mechani
