3D Printer Nozzle - Processing of 0.2mm Hole

With the development of small desktop 3D printers, more and more families use it for the creation and education of children, but the printing effect of 3D printing is also closely related to the nozzle. The nozzle is an easily consumed product, and its quality is directly affect the performance of the product.

At present, the most used inner holes are: 0.2mm, 0.3mm, 0.4mm. The nozzle determines the smoothness of the silk and the roundness of the silk. The smoothness of the inner wall is also very important. Generally, the smoothness of about Ra0.8 is the best, and the chamfer of the mouth is very important. We keep it below R0.1mm. The most important thing is that the concentricity between the inner hole and the small hole of the mouth must be kept below 0.01mm, so that the plastic will exert pressure under pressure, and the sprayed silk will be formed in a straight line, making the product effect more realistic.

The above is the experience summed up by our experiments in the processing process, you are welcome to research and refer to it.
