Multifunctional 3D printing pen

Abstract

The invention discloses a multifunctional 3D printing pen. The printing pen comprises a printing pen body, a multi-color ink box is arranged at the top of the printing pen body, and a spray head outersleeve is installed at the bottom of the printing pen body; the multi-color ink box is connected with the printing pen body through a rotating sleeve, moreover, ink outlets of the multi-color ink boxis connected with a pen material cavity through an ink outlet hose, and the pen material cavity communicates with a feeding port of the printing pen body through a plastic tube; the pen material cavity is sequentially provided with an air pressure cylinder, a heating electric sheet ring, a hydraulic pump and an electromagnetic heating ring from right to left, wherein a rubber gasket ring is installed on a piston rod of the air pressure cylinder, a main battery and a standby battery are symmetrically arranged on the two sides of the heating electric sheet ring respectively, and the main battery and the standby battery are provided with battery cover plates respectively; the hydraulic pump is arranged in the pen material cavity in a nested mode; and an adapter spray head is installed in themiddle of the spray head outer sleeve. According to the printing pen, quick color changing can be achieved through the multi-color ink box, moreover, the adapter spray head can be replaced conveniently, and the anti-blocking effect is achieved.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a multifunctional 3D printing pen. Background technique [0002] 3D printer (3DP) is a magical printer designed by an inventor named Enrico Dini, which can not only "print" a complete building, but even give Astronauts print any desired shape of the item. But what 3D prints out is the model of the object, not the function of the object. [0003] The 3D printing pen is the first pen with 3D printing function in the world. Using PLA and ABS plastics, the 3D printing pen can "write" on any surface, and even draw directly in the air. It is compact and requires no computer or computer software to support it. But in the prior art, most of the 3D printing pens used for printing have the following deficiencies: [0004] For example, the application number is 201710903992.2, and the patent name is an invention patent for a 3D printing pen: [0005] It connects two printing pens side by si...

Problems solved by technology

[0009] In order to overcome the deficiencies of the existing technical solutions, the present invention provides a multifunctional 3D printing pen, which not only solves the use problems caused by ordinary 3D printing pens, but also greatly increases the usability of the 3D printing pen and increases the efficiency of 3D printing. Moreover, it has a multi-color ink cartridge, which provides greater convenience for multi-color printing, can be charged and discharged, and is convenient to replace nozzles of different calibers, which can effectively solve the problems raised by the background technology
