Description

Technical Field

[0001] The present invention relates to the technical field of 3D printing cooling pipes, and in particular to a cooling water channel for anti-scaling 3D printing workpieces. Background Art

[0002] With the continuous development of science and technology, 3D printers have also come into being. 3D printing can directly generate molds of any shape from computer graphics data, thereby greatly shortening the production cycle of products and improving productivity. Since the working temperature of 3D printers when printing molds is high, the molds produced need to pass through cooling water channels for cooling and output.

[0003] However, general cooling water channels are fixedly installed inside the printer and are inconvenient to disassemble. In addition, the temperature of the cooling water in the channel will increase due to the transportation of the mold. Therefore, scale is easily accumulated and severely corroded in the cooling water channel of the 3D printer, which may lead to unqualified printed molds. Therefore, a device is provided that can achieve self-cleaning of scale and prevent large amounts of scale from accumulating inside the cooling water channel. Summary of the Invention
