Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing system suitable for high-viscosity liquid chemical mixing molding. Background technique [0002] 3D printing technology first originated in the United States at the end of the 19th century, and was developed and promoted in the 1980s. 3D printing is one of the latest high-dimensional manifestations of the fusion model of science and technology. At the end of the 19th century, the United States developed photographic sculpture and landform forming technology, and then produced the core manufacturing idea of ​​3D printing printing technology. [0003] After more than ten years of exploration and development, 3D printing technology has made great progress. At present, in developed countries in Europe and America, 3D printing technology has initially formed a successful commercial model. For example, in the fields of consumer electronics, aviation and automobile ma...

Problems solved by technology

[0007] In order to further expand its industrial application space, 3D printing technology still faces many bottlenecks and challenges: First, in terms of cost, the cost of existing 3D printers is generally relatively expensive, which brings difficulties to its further popularization and application

Second, in terms of printing materials, most of the molding materials for 3D printing currently use chemical polymers, the selection is limited, the physical properties of the molded products are poor, and there are certain hidden dangers in terms of safety.

The third is precision, speed and efficiency. At present, the precision of 3D printed products is not satisfactory, and the printing efficiency is far from meeting the needs of mass production. Moreover, due to the limitation of the working principle of the printer, there is a serious conflict between printing precision and speed.

Fourth, in terms of industrial environment, the popularization of 3D printing technology will make it easier for products to be copied and spread. The risk of piracy in the manufacturing industry will increase greatly. The existing intellectual property protection mechanism will not be able to meet the needs of the future development of the industry.

[0008] At present, the existing 3D printing system for high-viscosity liquid chemical hybrid molding mainly has the following disadvantages: In terms of defoaming and exhausting treatment of high-viscosity liquid materials, the existing exhaust method applied to 3D printing of high-viscosity liquid materials , the main method is to add a defoamer to the high-viscosity liquid to achieve the purpose of defoaming and exhausting. This chemical defoaming and exhausting method cannot completely and effectively eliminate the bubbles in the liquid.

The heat dissipation efficiency of this method is not high, because it is powered by the motor, which has a certain amount of noise. The longer the fan runs, the louder the noise

Due to the mechanical structure, it takes up a lot of space, and it is inconvenient to install near the 3D printing head, which seems to have a small space.

Once the blade fan is installed, the blowing direction is fixed, it can only dissipate heat in a single direction, and cannot dissipate heat in a 360-degree direction around the print head

There is a problem of uneven heat dissipation

Furthermore, the blade-type mechanical fan only has the single function of heat dissipation, and cannot perform dust removal and purification on the air inside the 3D printer, nor does it have the function of eliminating static electricity in the internal space.
