Abstract

The invention relates to a 3D printer. The 3D printer comprises a printing head and a printing workbench arranged at the bottom of the printing head; the printing head comprises a nozzle arranged at an extrusion port and a nozzle closing assembly; the nozzle closing assembly is provided with a blocking rod which can move relative to the nozzle, so that the nozzle is in a blocked state and an opened state; and the printing workbench comprises a heating plate and a printing platform detachably connected to the heating plate, and the printing platform is used for receiving materials flowing out of the nozzle. In a 3D printing machining process, when the position of the printing head is switched according to the machining requirement, the blocking rod is moved at the moment to enable the nozzle to be in the blocked state, and therefore the phenomenon that the materials are drawn and overflow from the interior of the nozzle is avoided, the heating plate is not polluted by the materials, and the heat conduction effect is good; and meanwhile, due to the fact that the materials overflowing to the heating plate are few, in the multiple heating processes, the number of the materials falling off from the heating plate and becoming impurities is small, and the machining quality and the machining efficiency of 3D printing products are high.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printer. Background technique [0002] 3D printing is a rapid prototyping technology, based on digital model files, using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. In recent years, as 3D printing technology has become more and more mature, it has been widely used in various industries. During the processing of 3D printing, the print head will switch positions due to processing needs. However, during the process of switching positions, the printing material will be drawn and overflow onto the heating plate, so that the heating plate will be printed material contaminated. When the heating plate is seriously polluted, the heat conduction effect of the heating plate will be affected at this time, and the overflowing material will fall off from the heating plate and become impurities during multiple heating process...
