People think this technique is nuts but it works and everyone who tries it realizes that.  People are afraid to try it.  They think the oil will come out the nozzle and mess things up.  But the oil doesn't affect the prints.

 

Add a drop of oil to the filament before sending it through the bowden so that the bowden gets tiny drops all around.  Then if possible, unspool the filament so it is hanging down and add one drop which will slide down a meter or so.  Every meter of printing add one drop of oil.

 

Adding oil (any oil but you don't want it to go rancid so use any kind of light machine oil like "3-in-one".

 

Other techniques: print much slower.  I've printed TPU as slow as 10mm/sec.

 

Also set the feeder to the lightest pressure (indicator all the way up).  Otherwise it will underextrude.

 

Print on the high temperature end of the suggested range.

    . I could not print

    This is vague but I assume you mean not much comes out of the nozzle.  Other issues might be that the part is not sticking well.  If that is your issue then let us know.

    Polymaker Factory settings Ultimaker S5 fails. Currently, printing works with the Ultimaker TPU settings. My question what I set incorrectly? Thx Gábor

    Sorry for the inaccuracy, I'm still a beginner... Cura sends the following message:

    Oh!  The retraction speed is set to 60.  That is what gets the error.  45 is the maximum value for the S5 printer.  Just set the retraction speed to 45.  

     

    Maybe you don't know how to do that...

     

    So click "custom" as shown here:

    Then enter the word "retraction" here and change it to 45.  Then you should be able to slice.

    You may be better with the Ultimaker TPU profile.  They said something about 1-3mm of retraction for TPU but that's not enough for an S5.  That recommendation is for a direct drive extruder.  Ultimaker doesn't sell any printers with that type of extruder.

    I liked this information. Thank you so much.

    I also print the material. I use the Generic TPU profile for this.

    I recommend a 0.8 nozzle for TPU.

     

    Many greetings

      • 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!
          • Thanks

      • 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.
