  With the rapid development of the times, 3D printers are a kind of rapid prototyping technology, also known as additive manufacturing. Now it is setting off a revolution in the manufacturing industry, attracting all kinds of permanent cures.

  Although the failure rate of 3D printers is low, once a failure occurs, it will not only affect the print quality, but also waste time printing materials and even damage the machine. At present, some 3D printing novices do not know what to do when the nozzles are clogged and there is no filament. 3D printers have a historical headache, which is easy to block! Many people guess that the temperature of the throat is too high, because it is additive manufacturing, and many raw materials need to be transported in the melted state of the printer head, and the material is fed The tube must meet the space requirements of the printer, so many manufacturers now use built-in Teflon throat pipes. The thermal conductivity of Teflon and stainless steel is low, which can effectively reduce the temperature of the throat pipe. The head failure rate is significantly reduced, so Teflon tubes have become the best choice for 3D printers. Here, as the source manufacturer, Shenzhen Dankai Fluoroplastics will explain to you why 3D printers cannot do without Teflon tubes.

  In 2015, the well-known 3D printer manufacturer Airwolf released its first civilian-level 3D printer. Teflon tubes are used in many key components. Because engineering grade materials require high continuous temperatures, the requirements for components are very high. Therefore, the 3D printer uses a Teflon tube as the feeder tube, and an isolation intermediate layer is added between the Teflon tube and the heater. In 3D printers, Teflon tubes are also widely used as the lining of extruder head tubes. The main reasons here are:

  1. Teflon will not bond with molten plastic;

  2. High temperature resistance. It can stay at the working temperature of 260℃ for a long time;

  3. The friction coefficient is small, the fluidity of the raw materials is good, and so on.

  Why do 3D printers choose Teflon tubes? This has a great relationship with the excellent performance of Teflon tubes. The production of Teflon tubes from Teflon tubes, my sister, briefly introduces its performance:

  1. Non-sticky: Teflon is inert, almost all materials are not bonded with Teflon, and the thin film also shows non-stick performance.

  2. Heat and cold resistance: Teflon has excellent heat and low temperature resistance. In a short time, it can withstand temperature to 300℃, melting point is 327℃, and it will not melt at 380℃. Generally, it can be used continuously between 240℃ and 260℃. It has remarkable thermal stability. It can work at freezing temperature. No embrittlement, cold resistance to 190℃.

  3. Lubricity: Teflon has a low coefficient of friction. The friction coefficient changes when the load is sliding, but the value is only between 0.04-0.15.

  4. Non-hygroscopicity: The surface of Teflon does not stick to water and oil, and it is not easy to stick to the solution during the production operation. If there is a small amount of dirt, it can be removed by simply wiping. Short downtime, saving working hours and improving work efficiency.

  5. Corrosion resistance: Teflon is hardly corroded by chemicals, and can withstand all strong acids (including aqua regia), strong alkalis, and strong acids except molten alkali metals, fluorinated media, and sodium hydroxide above 300°C. The role of oxidants, reducing agents and various organic solvents can protect parts from any kind of chemical corrosion.

  6. Weather resistance: non-aging, better non-aging life in plastics.

  7. Non-toxic: In the normal environment within 260℃, it is physiologically inert, non-toxic and can be used as medical and food equipment.

  8. Insulation: Very good dielectric constant and high insulation.

  If you have individual requirements for Teflon tubes, you can always consult Miss Teflon tubes. Due to the excellent performance of Teflon tubes, it is currently used in a wide range of applications. It can be used for pipeline anti-corrosion, high and low temperature resistance, and corrosion resistance. Used in harsh environments such as lubrication, electronics, electrical appliances, aerospace, and medical treatment.
