Where do you get your Teflon from? UK Peeps

Recommended Posts

Posted · Where do you get your Teflon from? UK Peeps

Hi Guys,

I have found a huge variance in the longevity of the Teflon couplers I have owned. I have two machines running 24/7 printing alot of similar prints. The original teflons lasted well into thier 1000 hour mark.

At those points i get extrusion issues and filament change issues so I change the teflon.

I then used the spares that came with the machines, they lasted less but probably closer to 600 hours.

Again same issue, so I decide to swop in new ones from the highly recommended 3dsolex. These really lasted alot less time, I mean ALOT less. realistically close to 200 hours max, before I started getting extrusion issues. No issues with changing filament though. They really feel like a very inferior product. (Plus the huge wait time to get them sent to the UK mixed with messed up orders etc..) Carl always tries to put things right, but a down time of a few days for me is quite a big loss, and so the mistakes coupled (see what i did there) with the very short lifespan is making me look elsewhere.

I have seen lots of people selling new Teflon couplers with "guarantees" that sound pretty odd to me. Has anyone used these? UK based people where are you buying your teflon and how long is it lasting you?

well mine last just 50Hrs (fifty) before get deformed!! But I preferred to modify it rather than replacing it... I thought that the problem of the coupler depend on the excessive pressure the spring put on it and that at the end of the print the filament get retired back too much, letting the hot plastics get in contact with the PTFE coupler!!

BUT.. you can avoid premature end of your coupler if as the print finish you enter in the Maintenance Menu-->Advanced-->Move Filament and move the filament back in the hot end rotating the knob ...made some kind of "priming" of your print head letting the filament come out for about 30-40 cm then make 1 (one) counter clockwise of the knob waiting the temp reach about 150°C (for ABS) or 90 for PLA and pull away the filament that came out.

This way you clean the small 0,4mm nozzle and inside the hod end your hot filament don't reach the PTFE coupler ;)

      Through this post I would like to further explain what we are doing, and what you could be doing. 
      Our efforts consist of 2 layers. First; connect medical institutions and hospitals to (local) 3D Printing hubs to help them print parts of which a 3D model already exists. And second, contribute to design the necessary part and then have it printed via a (local) 3D printing hub. Experts are available from within Ultimaker and from within our network of 3D printing experts.
