لوله PTFE مخصوص پرینتر سه بعدی با قطر خارجی 4 و قطر داخلی 3

Description :

The PTFE tube for 3D printers with an outer diameter of 4mm and an inner diameter of 3mm is a key component in the Bowden extruder system, designed to guide 3mm filament smoothly to the printer's nozzle. This PTFE Bowden tube is made from polytetrafluoroethylene (PTFE), a material known for its ultra-smooth surface, extremely low friction, and high resistance to heat and chemicals, ensuring optimal performance in 3D printing.

The 3x4mm PTFE tube has a non-stick surface, allowing the filament to pass through without clogs or friction buildup. This significantly reduces strain on the extruder while improving print quality. Additionally, its high flexibility ensures that the nozzle can move freely without putting stress on the filament, making it ideal for precise and consistent extrusion.

One of the key advantages of this 3mm filament guide tube is its exceptional heat resistance, capable of withstanding temperatures between -190°C to 280°C without deformation or performance degradation. Furthermore, its high chemical resistance to acids, strong oxidizers, and solvents enhances its durability and longevity.

This PTFE tube is compatible with a wide range of 3D printers, including Creality, Prusa, Anycubic, and many other popular models. It is also eco-friendly and free from harmful substances, making it a safe and reliable choice for 3D printing applications.

How to Use the PTFE Tube for 3D Printers:

Precise Cutting of the Tube:
Before installation, use a PTFE cutter or a sharp blade to make a clean and straight cut. This ensures optimal filament flow and reduces printing issues.

Connection to the Bowden Extruder:
Connect one end of the PTFE tube to the pneumatic fitting on the Bowden extruder. Make sure the tube is securely inserted into the fitting to prevent any leaks.

Connection to the Hot-End Input:
Attach the other end of the tube to the hot-end connector, ensuring it is securely placed. Some printers may use a metal or pneumatic coupler for this connection.

Check the Filament Flow:
After installation, feed filament through the tube and ensure it moves smoothly without resistance. If any issues arise, check that the tube is not bent or clogged.

Maintenance and Replacement:
Over time, the PTFE tube may wear out or get clogged. Replacing it will improve the printer's performance and print quality. Additionally, keep the tube clean and prevent dust from entering it.

Tip: Some 3D printers use higher-quality PTFE tubes like Capricorn PTFE to enhance precision and reduce friction, which is especially useful for printing with delicate filaments like TPU and PETG.
