Filament stuck in PEEK


Recommended Posts

Posted · Filament stuck in PEEK

I've been having this problem extruding filament and after taking my extruder head apart I discovered that the filament is not passing through the peek anymore to reach the head and extrude. It seems that the reason this is happening is that there's some plastic stuck on the inside wall of the peek. I've tried unscrewing the tube that goes into peek but that only resulted in my pliers bruising the twisty part that screws into the heater. regardless of how this problem originated does anybody have any advice in regards to cleaning out the residue plastic on the inside of the peek to get my filament to go through or should I just order new parts?


Any help would be much appreciated as I've been dying to get some prints out. Thanks

    The peek melts around 300C. PLA around 200C. Heat to 240C and blow it out with compressed air or use high G's for example by tapping it on a table.

    I've never tied this myself so there may be something I didn't think of. Like how to heat to 200C but not go over 300C. Oven maybe? I have a hot air heat gun so I would use that but I'd have to be careful not to get too hot.

    Thanks for the advice, I don't really have access to any way to heat it over 200C though so maybe I'll just order new parts..


    Many people/apartments have an oven (to bake or cook)... you could just heat it up to 200C and let the PEEK warm up.

    Many people have a stove to boil water: you could just drop the PEEK into boiling water, and let the PLA get a bit soft (Tg is 65C).

    Many people who were alive in the past 250000 years have managed to make a fire to cook and boil some water with a wide variety of fuels and cooking containers.

    Many people have a hair dryer, which also lets you heat up the PEEK beyond 65C.

    I am sorry to hear you don't have access to any of those.

    Many people have access to an online community that's not full of dead links, where the veterans are understanding and don't give sarcastic answers but I guess I don't have that either.

    As for the stove, I live in a small old Japanese house that gets no gas or hot water, as for the other stuff, I assumed the PLA melts around 200 or so since that's always what I need to set my printer to?

    In the end I got it working with new parts.

    jdudeo, sorry but it's just hard to believe someone can afford to buy a UM and not know anyone who owns a temperature controlled oven. It just seemed like you hadn't thought it through.

    So you don't have access to boiled water? Or hot tea? Or cooked Rice? You don't know anyone with a stove or oven who would let you borrow it for a half hour? I'm sorry if that is true. I'm not being mean or sarcastic. It just seemed like you asked such a simple question and the answer was so simple that it was annoying that you bothered us with such a simple question. It was like you asked "how do I tighten these screws?".

    Ah - I suppose boiled water is only 100C and you thought you had to go to 200C so maybe you knew that. But no access to an oven?

    Anyway good luck with your UM and don't be afraid to ask more questions.

    Have you been to Japan? Believe it or not it's not common to own or have any use for an oven.. I could explain further why I thought it was easier to just order the part but I'd rather save us all the hassle of carrying on this conversation.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
