Capricorn XS Series Premium PTFE Heatbreak Liner

This XS Series Premium PTFE Heatbreak Liner is made from the same material as the XS Series PTFE Bowden tube. It was specifically designed for heatbreaks that are lined with a PTFE tube and have a diameter of 2.0mm by 3.0mm. Most 3D Printers only need about 3cm for each use so 15cm will give you enough for about 5 heatbreaks. PTFE lined hot ends produce better results with PLA filaments because the filament is less likely to stick and jam inside the heat break. For higher temperature filaments, “all-metal” hot ends are generally recommended, but the high-temperature additives in our XS Series Premium PTFE Heatbreak Liner allow it to perform better than typical PTFE in these applications, providing the best of both worlds.

High-Temperature Resistance
The high-temperature additive improves the thermal properties of the PTFE, allowing it to print at higher temperatures for longer duty cycles. Our XS tubing will operate at even higher temperatures than our TL. See our Safety page for more details about high-temperature printing.

Safety Precautions

PTFE is a fluoropolymer, which exists in a state of matter known as a “glass.” This means it does not “melt,” like an ice cube, but rather slowly gets softer and softer as it gets warmer. Eventually, it will either become a liquid or catch fire. Between room temperature and catching fire, all polymers emit tiny amounts of harmful gasses, known as “off-gassing.” The hotter they get, the more they will emit.

Because our PTFE tends to have better temperature resistance (meaning it stays firmer at higher temperatures before significant deformation) than lower quality PTFE tubes, a number of users have reported success using it “inside the hot end.” This is not something you should do willy-nilly. Just because it works, doesn’t mean there aren’t precautions to be taken. If you use PTFE, or any polymer for that matter, inside the hot end or anywhere excessive temperatures may be experienced, you will potentially create harmful off-gassing. Not only that, but the polymer you are extruding may be creating harmful gasses as well.

It is not recommended to use XS Series Premium PTFE Heatbreak Liner in the heatbreak if you plan to print above 200C. You should change your heartbreak to an all-metal heartbreak for high-temperature filament printing.

We strongly recommend running your 3D printer in a well-ventilated area, away from children and pets.
In a classroom environment, we encourage printing with PLA and staying away from higher temperature materials, whether you use our Bowden tubing or not. Always have adult supervision when operating a 3D printer. Keep razor-sharp Bowden tubing cutters out of reach of children.

Have fun, and stay safe out there!
