Problems solved by technology

However, this structure has the following disadvantages: heating by hot air, the efficiency is low, and only the liquid surface receives the action of the heat source; the thermal conductivity of the resin is poor, resulting in uneven heating, resulting in local overheating of the resin, which will cause denaturation of the resin and affect the use, and there is a large temperature Gradients, which can lead to large deformations of molded parts due to temperature differences

Embodiment Construction

[0023] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

[0024] Such as figure 2 , image 3 , Figure 4 and Figure 5 As shown, a resin tank of a 3D printer includes an inner tank 2 and a shell 1 covering the inner tank 2. The four walls of the inner tank 2 are made of heat-conducting materials to facilitate heat conduction. If aluminum alloy is used, it has good thermal conductivity. The outer walls around the inner tank 2 are equipped with heating blocks 3, the heating blocks 3 are closely attached to the inner tank 2, and the heat emitted by the heating block 3 is conducted to the photosensitive resin contained in the inner tank 2 through the four walls of the inner tank 2. To avoid accidental burns caused by external contact with the heating block 3 , the heating block 3 is located in the casing 1 . The heating block 3 includes a heat conduction s...

Abstract

The invention provides a resin tank for a 3D printer, which includes an inner tank and a shell covering the inner tank. The four walls of the inner tank are made of heat-conducting materials, and the outer walls around the inner tank are provided with heating blocks, and the heating blocks are located between the inner tank and the outer shell. Among them, the heating block includes a heat-conducting substrate and a heating wire embedded in the heat-conducting substrate, and the heating wire is connected to a power source. The invention is provided with a heating block to increase the heating area of ​​the resin tank, and the heating is uniform, which is beneficial to improving the heating efficiency, and the photosensitive resin is evenly heated to avoid deformation of the product.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a resin tank of a 3D printer. Background technique [0002] Light-curing 3D printing equipment is a kind of equipment that uses certain wavelengths of light to cure photosensitive resins. It is a common type of 3D printer on the market. There are resin tanks in this type of equipment, and the resin tank is a container for holding photosensitive resin. In the 3D printing process, after each layer is cured, the worktable moves a layer thickness distance, and then spreads the resin to prepare for the next layer to be cured. Photosensitive resin has high viscosity and poor fluidity. When spreading, some areas will not be filled with resin. This is especially serious when printing large flat objects, which greatly affects the success rate and printing quality of printing. Properly heating the resin and increasing the temperature of the resin can improve the fluidity of the resin and solve...
