Abstract

The invention discloses a novel printing head for a 3D printer. The novel printing head comprises a heat dissipation assembly, a throat pipe, a heating assembly and a nozzle, the upper end of the throat pipe is connected with a feeding channel of the heat dissipation assembly, the lower end of the throat pipe is connected with the nozzle, the bottom of the nozzle is located below the heating assembly, connecting columns are arranged between the heat dissipation assembly and the heating assembly, the heat dissipation assembly and the heating assembly are connected through the connecting columns, and the outer sides of the connecting columns are sleeved with heat insulation sleeves. According to the printing head, heat transfer between the heating assembly and the heat dissipation assembly can be well blocked, and the influence on the heat dissipation effect of the heat dissipation assembly is reduced.

Description

technical field [0001] The invention relates to the technical field of 3D printing, more specifically, a novel printing head for a 3D printer. Background technique [0002] The 3D printer of the FDM process generally uses filamentous or granular consumables. Through temperature control, the consumables enter a molten state, extruded through a nozzle, and laid out according to a set path under program control. Among them, the extrusion control part of the consumables is called the print head (Hotend). The print head is composed of a radiator, a throat, a heating block and a nozzle. The print head is the core component of a 3D printer, and its performance will directly affect the 3D printer. overall performance. [0003] Temperature control is an important function of the 3D printing head. It can quickly and effectively dissipate heat from the throat, which can reduce the temperature of the consumables before they enter the nozzle melting cavity, so that the consumables can m...
