YOOPAI PTFE Teflon Tubing 5m with Cutter, 2.5mm ID × 4mm OD PTFE Teflon Tube Fits Direct Drive Extruder 3D Printer, for Bambu Lab A1/A1 mini/P1P/P1S/X1C for Creality K1/K1 Max/Ender 3 V3 (White)

Fit and Compatibility: The Ultra-Smooth PTFE Teflon Tubing 1.2m is a perfect fit for the Bambu Labs A1 3D printers. The dimensions are spot-on, ensuring that the tubing slides in seamlessly without any need for adjustments. This precise fit is crucial for maintaining consistent filament flow during printing. Length: The 1.2m length of this tubing is exactly what’s needed for the Bambu Labs A1. It provides just the right amount of slack to accommodate the printer's movements without being too long, which could cause unnecessary bends or loops. This length is ideal for ensuring that the filament path remains straight and unobstructed, contributing to smoother and more reliable prints. Performance: In terms of performance, the PTFE Teflon material offers excellent low-friction properties, which is essential for reducing resistance as the filament moves through the tube. This helps to minimize the chances of filament jams or extruder skipping, especially when using more flexible or delicate filaments. The tubing’s ultra-smooth interior surface contributes to consistent filament feeding, which is crucial for maintaining high print quality. Durability: PTFE tubing is generally known for its heat resistance and long lifespan, especially when used in a 3D printing context. It's likely that this tubing will hold up well over time, even with frequent use. Overall Impression: The Ultra-Smooth PTFE Teflon Tubing 1.2m appears to be an excellent choice for anyone using Bambu Labs A1 3D printers. With its precise fit, ideal length, and performance-enhancing properties, it seems to contribute significantly to the reliability and quality of your prints.

This is great for moving filament from your storage unit to the printer. The larger inner diameter of 2.5mm GREATLY reduces friction on the filament, which makes a big difference with abrasive filaments like glow in the dark or wood grain filament. Outer diameter is still 4mm so existing connectors hold it in just fine. Installation is easy with the included cutter, just cut it to whatever length and replace your old PTFE tube. I've been happy with the quality so far- ran lots of abrasive stuff through it and it still feeds 'difficult' filaments like soft TPU just fine. One caution- you ONLY want to use this *before* the extruder. IE, from spool to printer. If you use it AFTER the extruder, IE as the Bowden tube in an Ender 3, the filament will have a lot more 'give' and that will reduce the accuracy of the prints. However used before the extruder gears- from spool to printer or printer to print head, the functionality is perfect and filament feeds much more smoothly. Keep in mind with the thinner walls it can kink more easily, so if you're hooking up the extruder on a K1 series printer with this you might want to print a support of some kind for it. Definitely recommended!

Needed some PTFE for my Bambu printer and these did not disappoint. Works well and able to see my filaments inside. Great price as well.

fast shipping and reasonbly priced the tubing works great and the cutters are ok, still crimped the tubing a bit but they work

Used this to replace my PTFE tubing on my Bambu P1S to have a nice continuous piece from the print head to the filament buffer. No more fumbling with PTFE connectors and blocked tubes. Excellent replacement and the included cutter is great!

Why did you pick this product vs others?: This thing was perfect for replacing by line. It worked great. Size: Perfect size Cut quality: Adding the cutter makes it a quality cut Print quality: It helped a lot with my printing as it wasn’t struggling to feed it filament Fit: Perfect fit

Works great in my Bambu Labs H2D. Just as good, but much cheaper than, factory parts.

Works great for replacement PTFE tubing. Installed some on my Bambu P1S. Will be using to replace all PTFE tubing on my machines. I would recommend.
