Problems solved by technology

[0004] Existing 3D printing pens mainly include casing, wire feeding mechanism, control mechanism, heating block and nozzle, etc. The filament is in a high temperature state at the front end of the nozzle for a long time. One problem is that when printing continues, the molten filament is too hot and the subsequent filament becomes soft. When the extrusion gear continues to operate, the molten filament cannot be effectively extruded, resulting in nozzle blockage or difficulty in forming three-dimensional objects.

Abstract

The invention provides a 3D printing pen comprising a shell, a control button and a nozzle. An opening is formed in the first end of the shell; the control button is installed on the shell; and the nozzle is arranged at the first end of the shell and stretches out of the opening. The 3D printing pen further comprises a fixed part, a movable part and a cooling device; the fixed part is arranged at the position, close to the opening, on the shell and provided with a conductive part; the movable part and the fixed part are in sliding fit in the circumferential direction of the shell; at least part of the movable part is made from a conductive material; the cooling device is movably connected with the movable part and internally provided with a cooling fan and a motor; and an air outlet is formed in the end portion of the cooling device and corresponds to the end portion of the nozzle. The cooling device can rotate in the circumferential direction of the shell and can also rotate around the movable part, the orientation of the cooling device can be adjusted as required, the cooling fan rotates after being powered on, cold air is discharged out of the air outlet, and a good cooling effect is achieved. The invention further provides a printing method of the 3D printing pen.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a 3D printing pen and a printing method thereof. Background technique [0002] 3D printing is a technology that uses materials such as plastic or powdered metal to construct three-dimensional objects by layer-by-layer printing. 3D printing is usually achieved by printing with 3D printers. With the development of 3D printing technology, 3D printing pen, as a handheld device that uses additive manufacturing technology to print 3D objects, is very popular because it can easily print 3D objects. Compared with 3D printers, 3D printing pens can not only allow users to doodle out 3D models with individuality, but also have the advantages of simple structure, small size and easy portability. [0003] At present, the fused deposition manufacturing (FDM) type 3D printing pen on the market mainly heats the linear filament into a molten state through a high-temperature nozzle, and extrudes the mo...
