Peristaltic pump type 3D printing pen

Abstract

The invention discloses a peristaltic pump type 3D printing pen comprising a pen shell, a pen head, a feeding pipe, a peristaltic pump, a discharge pipe, a heat preservation chamber and a circuit module; one end of the feeding pipe is provided with a joint, and the other end of the feeding pipe end is connected with the input end of the peristaltic pump; one end of the discharge pipe is connected with the heat preservation chamber, and the other end of the discharge pipe is communicated with the output end of the peristaltic pump; the heat preservation chamber is communicated with the pen head, and the peristaltic pump is in electric connection with the circuit module; the peristaltic pump type 3D printing pen has the characteristics of being uniform and controllable in discharging speed, wide in application range, flexible in use, and controllable by a 3D printer.

Description

technical field [0001] The invention relates to a peristaltic pump type 3D printing pen. 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 three-dimensional 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 plastic filament as raw material. It has the following disadvantages: it can be used The raw material is single, and the application range is limited; the extrusion speed of the raw material is uneven, and the problem of heat dissipation needs to be considered, which increases the volume of the pen and is not flexible to use. Contents of the invention [0003] The technical problem to be so...
