A 3D printing pen with adjustable caliber

Abstract

The invention discloses a caliber-adjustable 3D (three-dimensional) printing pen which comprises a pen shell. A controller is mounted on one side of the pen shell, a feeding pipe is arranged at the middle of one inner end of the pen shell, a motor is fixed in the pen shell of one end of the feeding pipe and electrically connected with the controller, the output end of the motor is fixedly connected with a gear, a guide wheel is mounted in the pen shell of one side of the gear, a pen head is fixedly connected with the other end of the pen shell, a cooling pipe is arranged at the middle of the top of the pen head, and a melt cavity is formed in the pen head below the cooling pipe. According to the printing pen, a second discharging head and a third discharging head extends out of end of a first discharging head by rotating a first nut and a second nut, so that the hole diameter of the 3D printing pen is changed, the 3D printing pen is convenience in drawing and convenient to use, a resetspring can pull a second piston and a first piston to move upwards when feeding is stopped, molten materials are pumped into the melt cavity and a discharging channel, and wire drawing caused by material overflowing after feeding stop is prevented.

Description

technical field [0001] The invention relates to the technical field of 3D printing pens, in particular to a 3D printing pen with adjustable caliber. Background technique [0002] With the development of science and technology, 3D printing technology is more and more widely used in various fields. At the same time, 3D printing technology also appears in people's life in the form of more types of products, and 3D printing pen is one of them. Different from 3D printers that realize 3D printing through the movement of the printing nozzle driven by the mechanical arm, the 3D printing pen is controlled by human hands, and the 3D printing pen can realize three-dimensional painting according to the wishes of the person, that is to say, the user only needs to use the traditional paintbrush to operate It is possible to draw a three-dimensional pattern in a three-dimensional environment. [0003] At present, the 3D printing pens on the market use a single function of the nib, and the ...

AI Technical Summary

Problems solved by technology

[0003] At present, the 3D printing pens on the market use a single function of the nib, and the same 3D printing pen cannot meet the various creative needs of the user at the same time, such as: handwriting thickness, handwriting shape, special functions of the pen, etc. At the same time, when creating, stop feeding There will also be part of the material overflowing, resulting in wire drawing, reducing the aesthetics of the work
