A 3D printing pen for easy color matching

Abstract

The invention discloses a 3d printing pen capable of conveniently achieving color matching. The 3d printing pen comprises a printing pen body and a printing pen head, a photosensitive resin storing cylinder is arranged in the middle of the top of the interior of the printing pen body, and seven pigment cylinders are evenly arranged on the portions, on the outer side of the photosensitive resin storing cylinder, of the interior of the printing pen body along a concentric circle. According to the 3d printing pen capable of conveniently achieving color matching, it can be conveniently guaranteedthat the pressing pressure of a pressing plate and the pressing pressure of a pressing base are consistent, then it is guaranteed that the proportion of photosensitive materials to pigments is 1:1, and use is convenient; and at the moment of hole diameter increasing, the tension of a second reset spring changes as the internal pressure and the top pressure are invariable, then the pressing base achieves instant springback towards the interiors of the pigment cylinders and the photosensitive resin storing cylinder, the internal pressure can be conveniently increased, time difference caused by one moment is prevented, then waste materials are prevented from being generated, the size of a discharging port can be conveniently adjusted, therefore, the working efficiency is improved, the photosensitive resin solution and pigment flowing time is conveniently prolonged, and the mixing efficiency is conveniently improved.

Description

technical field [0001] The invention relates to the technical field of printing pens, in particular to a 3D printing pen that is convenient for color matching. 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. The handheld 3D printing pen is mainly divided into two types: hot-melt type and light-curing type. The light-curing 3D printing pen extrudes liquid photosensitive resin, which is cured and formed under the action of ultraviolet light. Its processing flexibility and final printing body There are certain advantages in the texture fineness, and the optional and combination types and ranges of photosensitive materials are also very flexible. [0003] Although the existing 3D printing pen can use the principle of three primary colors to modulate different colors, it ...

AI Technical Summary

Problems solved by technology

[0003] Although the existing 3D printing pen can use the principle of three primary colors to modulate different colors, it only modulates its own color, and there is no direct use of photosensitive materials and pigments to directly mix it for color matching. In the process, when faced with multiple materials, the material is often conveyed through multiple pressures, but this increases the weight of the pen, which affects the use of the pen. The nib is disassembled to replace other nibs to adjust the size of the discharge aperture, which is inconvenient to use and too cumbersome to replace
