A 3D printing pen that is convenient for porous discharge

Abstract

The invention discloses a 3D printing pen which is convenient for porous discharge, which comprises a printing pen body, a feeding pipe, a mixing cylinder and a connecting seat. The inside of the printing pen body is provided with a feeding pipe in the form of a four-way pipe. The end of the feed pipe away from the liquid material tank is connected with a mixing cylinder, the bottom of the printing pen body below the mixing cylinder is connected with a connecting seat, and the top of the connecting seat is connected with a rotating block through a bearing. The invention ensures the ratio of the photosensitive resin liquid in each feeding tube, ensures the purity of the required color, and at the same time modulates according to the required amount. On the one hand, the second helical stirring shaft and the first The spiral stirring shaft stirs the photosensitive resin liquid, on the other hand, it provides a pressure for the photosensitive resin liquid until the extruding plate and the top of the mixing barrel are in contact with each other, so that the photosensitive resin liquid can be completely discharged to prevent waste, and it is convenient to adjust the unit freely. Hole output and multi-hole output, so as to speed up the printing speed and improve work efficiency.

Description

technical field [0001] The invention relates to the technical field of 3D printing pens for porous discharge, in particular to a 3D printing pen for porous discharge. 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 3d printing pen that is convenient for porous discharge is One of them, the current hand-held 3D printing pen for porous discharge is mainly divided into two types: hot-melt type and light-curing type. The light-curable 3D printing pen for porous discharge extrudes liquid photosensitive resin, Curing and molding under the action of irradiation has certain advantages in processing flexibility and texture fineness of the final printed body, and the optional and combined types and ranges of photosensitive materials are also very flexible.

Problems solved by technology

[0003] Although the existing 3D printing pens that are convenient for porous discharge can use the principle of three primary colors to modulate different colors for writing and printing, they cannot ensure the mixing and matching ratio of two and three colors during the modulation process, so that It is impossible to ensure the purity of the required color, and at the same time, it is impossible to control the amount used, and it is easy to cause residue inside the printing pen. When other colors are required, it cannot be modulated. At the same time, the existing 3D printing that is convenient for porous discharge The pen cannot realize the phenomenon that multiple nibs are used at the same time on one pen, so that multiple nibs can work at the same time for the place that needs to be painted, thereby increasing the printing speed
