Capricorn Bowden PTFE Tubing XS Series 1 Meter for 1.75mm Filament (Genuine Capricorn Premium Tubing)

Bowden Tube to finish off my printer upgrade to direct drive.

I have purchased three capricorn xs tubes already, the initial experience was unsatisfying and full of self errors, the bowden tube I cut was not cut straight and my filament also needed to be cut, once that was resolved I printed petg on two different types of machines, one with a through hole 1.75mm heatbreak so the tube was directly on the nozzle and one with a capricorn ptfe liner 1.75mm as well. The retraction and temperature consistency was different and certain artifacts dissappeared from my prints such as ghosting and some retraction lines and blobs, I strictly print petg filament right now and am satisfied with the finish, please take note of a couple of extra steps that need to be taken to avoid jams and pressure on the push fittings; 1) always make sure your cut is straight and clean, 2) double check filament tip if inserting different roll of filament as it can cause back pressure that may ruin certain push fittings and cause them to stop working. There are some precautions with filament changing though but they are no big deal, no cold pulls or the filament may get stuck in the ptfe tube so pull it while its hot and clean up the tip. I will definetely buy again.

I started trying to print PETG with my printer. Apparently the nozzle cools a bit more on the outside than they temperature sensor would lead you to believe, so when printing with PETG, I have to turn the temps up a bit further past what is recommended for standard PTFE tubing. About the 235c mark. I haven't had major issues, but I did get a clog, and when taken apart, not so surprisingly, the PTFE tubing I originally had in it was melting and slowly starting to get sucked into the nozzle, which caused the jam. Bought this stuff knowing the name from general interest in 3d printing, knowing it "should" be better for filament flex in bowden systems.It works great. I've pumped the heat up to 250c without any issues. The XS series theoretically supports up to 340c temps. This means you can print with stuff like NylonX (haven't tried it yet) and still have a ton of headroom before the tube would melt. Simple upgrade that isn't really all that expensive, but can potentially allow you to use many more kinds of filaments.

The bowden tube that comes with a stock Ender 3 is bad.This is better. It's more slippery and narrow and filament feeds through without much effort. A bonus is that it looks nicer, too. Comes with enough length for two uses.It does not last forever, however. I got about six months of on-and-off printing before mine was burned and crimped enough to need replacing.

I purchased this 1.75mm PTFE Capricorn tubing to replace the stock PTFE tubing on several MDG CR10v3s with Bondtech LGX extruders with Slicer Mosquito hotends.This arrived a little slowly but was packaged well and safely.I was immediately pleased that this order of Capricorn tubing came with several quality brass fittings (this doesn't always happen apparently) in the package. Capricorn PTFE tubing is superior in quality, inner diameter consistency, and for maintaining rigidity on bends /curves. This allows a smoother filament path for the filament to travel in. This results in cleaner prints and lower resistance on the extruder.I would definitely recommend this to others.

I bought this to replace the PTFE tube inside my MK10 hot end since I have been battling heat creep printing PETG. I was hoping this was the secret sauce but like PTFE it eventually would have a soldered clog in the tube in the throat area between the hot and cold zones. I also noticed this tube was smaller in diameter than the other PTFE I'd buy as they would snugly fit in the throat but this has enough play to rattle around so to speak in the throat.For those who care I use multiple PETG's and typically print in the 232-240 range depending on the filament. If I even use retractions they are limited to no more than 3/30 but typically 2/30 if at all. I've been getting to the point lately of skipping infill and increasing wall/top/bottom layers to avoid even having to use retractions and my PETG print success has gone way up. Long prints though still suffer from heat creep that I do not experience with ABS at the same temps. Thats the PETG trade off though, slow down the prints to a point PETG likes and seriously risk or definitely get heat creep.

Long as you set the correct depth in the hot end you'll have better prints and the bowden setup can push the filament in a more consistent manner with my metal extruder upgrades. Running 2 3d printers consistently and this tubing has helped. I use this from extruder to hot end and then I use traditional bowden tube from my drier to extruder so my filament it's always sealed from drier to hot end.

Best bowden on the market.
