3d printing pen convenient for porous discharging

Abstract

The invention discloses a 3d printing pen convenient for porous discharging. The 3d printing pen convenient for the porous discharging comprises a printing pen body, feeding pipes, a mixing cylinder and connecting seats. The printing pen body is internally provided with the feeding pipes which form a four-way pipe; the mixing cylinder is connected to the end, away from liquid material tanks, of the feeding pipes; the connecting seats are connected to the bottom of the printing pen body under the mixing cylinder, and the tops of the connecting seats are connected with rotating blocks through bearings. According to the 3d printing pen convenient for the porous discharging, the proportion of photosensitive resin liquids in each feeding pipe and the purity of the required color are ensured, and adjustments can be carried out according to the required amount; in the extrusion process, on the one hand, the photosensitive resin liquids can be stirred by a second spiral type stirring shaft anda first spiral type stirring shaft, on the other hand, pressure is provided for the photosensitive resin liquids until an extrusion plate makes contact with the top of the mixing cylinder, so that the photosensitive resin liquids can be discharged completely, the waste can be prevented, single-hole outputting and porous outputting can be adjusted freely and conveniently, and thus the printing speed is increased, and the working efficiency is improved.

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
