Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing equipment, and in particular to a heat-source-free 3D printing material drying device. Background Art

[0002] 3D printing materials are hydrophilic, which can easily cause the materials to become damp. The moisture absorption of 3D printing materials will not only reduce the molecular weight of the materials and make them brittle, but also, under high-temperature processing, the internal water molecules will boil due to heat, and a series of bubbles will form on the surface of the molded objects, accompanied by problems such as drawing, rough surface, and whitening. Therefore, it is necessary to keep the 3D printing materials dry. At present, there are roughly two types of 3D printing material drying equipment on the market. One is to dry 3D printing materials by using a built-in heating module. The heating methods include heating film, heating wire, heating chip, etc.; the other is to place a desiccant in a closed environment. However, the above two methods have some disadvantages. 1. The use of a built-in heating module consumes energy and increases costs; 2. The method of placing a desiccant in a closed environment is inefficient and time-consuming. Utility Model Content

[0003] The purpose of the utility model is to provide a heat-free 3D printing material drying device to solve the above-mentioned problems, help users save energy consumption, and dry 3D printing materials using the heat generated when the 3D printer is working without a heating system.

[0004] Technical solution: The utility model provides a heat source-free 3D printing material drying device, including a drying device, wherein the drying device includes: a shell, a heat extraction mechanism, a desiccant, and a thermometer and hygrometer; the heat extraction mechanism includes: a fan and a ventilation hose, wherein the fan is arranged at the lower end of one side of the shell, and the ventilation hose is connected to the fan on the outside of the shell; the desiccant is arranged at the lower part of the shell; and the thermometer and hygrometer is arranged in the middle of the shell.

[0005] Furthermore, in the above-mentioned heat source-free 3D printing material drying device, a power interface is provided on one side below the shell.

[0006] Furthermore, in the above-mentioned heat source-free 3D printing material drying device, the lower part of the shell is a rectangular parallelepiped structure, and the upper part is an arc-shaped convex structure.

[0007] Furthermore, in the above-mentioned heat source-free 3D printing material drying equipment, a 3D printing material storage box is provided inside the shell, and the 3D printing material storage box is a circular structure, the center of the circle is at the same position as the arc-shaped protruding structure on the upper part of the shell, and a cylindrical protrusion protruding inward is provided at the center of the circle, and the thermometer and hygrometer are arranged on the cylindrical protrusion.

[0008] Furthermore, in the above-mentioned heat-source-free 3D printing material drying device, the other end of the ventilation hose is connected to the 3D printer. The heat generated by the 3D printer during operation is rotated by the fan, and the hot air is sucked into the drying device through the ventilation hose to dry the 3D printing material.

[0009] Furthermore, in the above-mentioned heat source-free 3D printing material drying device, the drying device and the 3D printer are both arranged on a workbench.

[0010] Furthermore, in the above-mentioned heat source-free 3D printing material drying device, a vent is provided below the 3D printing material storage box.

[0011] It can be seen from the above technical scheme that the utility model has the following beneficial effects: the heat-source-free 3D printing material drying equipment described in the utility model dissipates the heat generated by the 3D printer when it is working through fan exhaust, and draws the hot air in the 3D printer into the drying equipment through the ventilation hose to dry the 3D printing material, thereby improving the drying effect and solving the heat dissipation problem of the 3D printer. The heat energy generated by the 3D printer itself is used to dry the 3D printing material, which saves energy, reduces costs, and contributes to energy conservation and emission reduction.
