Problems solved by technology

[0002] With the rapid development of 3D printing technology, 3D printing technology is more and more widely used in people's daily life. 3D printing pen is popular as a tool that can conveniently construct three-dimensional models. It can be used for graffiti Creating a personalized 3D model can also cultivate the user's spatial imagination; the existing 3D printing pen can only extrude hot-melt plastic through internal heating as raw material, and can only use linear plastic as raw material, which has the following disadvantages : The available raw materials are single, and the scope of application is limited; the extrusion speed of raw materials is uneven, and the problem of heat dissipation needs to be considered, which increases the volume of the pen, and the use is not flexible

Abstract

The invention discloses a piston type 3D printing pen comprising a pen shell, a pen head, a first feeding pipe, a second feeding pipe, a piston cylinder, a piston rod, a piston movement driving device, a first conveying pipe, a second conveying pipe, a solenoid directional valve, a discharging pipe and a circuit module; the piston type 3D printing pen has the characteristics of being uniform and controllable in continuous discharging speed, wide in application range, flexible in use, and controllable by a 3D printer.

Description

technical field [0001] The invention relates to a piston type 3D printing pen capable of continuous printing. Background technique [0002] With the rapid development of 3D printing technology, 3D printing technology is more and more widely used in people's daily life. 3D printing pen is popular as a tool that can conveniently construct three-dimensional models. It can be used for graffiti Creating a personalized 3D model can also cultivate the user's spatial imagination; the existing 3D printing pen can only extrude hot-melt plastic through internal heating as raw material, and can only use linear plastic as raw material, which has the following disadvantages : The available raw materials are single, and the scope of application is limited; the extrusion speed of raw materials is uneven, and heat dissipation needs to be considered to increase the volume of the pen, which is inflexible in use. Contents of the invention [0003] The technical problem to be solved by the pr...
