1.75 nylon instead of the 3.0

would it be possible to use the 1.75 nylon instead of the 3.0?

The 3.0 has thicker parts, up to 3.17 mm, getting stuck into the bowden.

(and of course always at the end of a project, destroying the whole thing)

I tried to run it through a 2.9 mm hole, but it just flexes back, it doesn't stretch.

 

when using a continuous design, like a vase or bracelet "joris style' with no retraction,

would it be possible to use 1.75 mm, so just pushing.....

would the filament drive have enough pressure to push it through?

it might flex a bit inside the bowden, but this stuff is slippery enough to slide through, I guess...

 

are there more settings to adjust than the filament diameter?

    I think that the molten plastic will be pushed upwards, around the incomming filament. Normally, the 3.00 mm closes the gap, so the molten filament can only go one way, out the nozzle. But with 1.75 the sides are open...

    1.75 Mm

    I agree with BaasB... however if you reduce the flow speed... and I guess, it can be tricky to find the right speed... then I would say it's possible... but I have never tried it myself and I'm also very curious if it's possible or not.

    Please update to us if you get some results :)

    i tried a little easy print .....and it works......so far.......

    adjusted the filament diameter to 1.75

    layer thickness: 0.1

    temp. 245

    slow, 25 mm/sec

    the only thing I had to change was the part that pushes the filament to the bolt,

    the old part (v1) had the best pressure, the new spring part did not get far enough

    Sounds very interesting! It's actually a very good news because it means that even if sometimes we cannot get a 3mm filament, we can still get 1.75mm and we can be able to print with Ultimaker :-)

    I have just run some trials with 1.75mm filament in my Ultimaker. Video on Youtube next week. Simply get a meter of PTFE tube and insert it into the bowden tube.

    I don't have a tube that size..

    and wanted to try it out anyway

    first test was OK

    0.2 layerheight

    speed in Cura 25mm/sec, upped to 135%

    temp: started with 245, the colors faded to brown

    lowered to 240, the blue came out better

    lowered to 236, but that part delaminated later

    upped to 240 again

    during printing you could see the filament curling up in the bowden, so once in a while I released the extruder closure to get the tension out.

    Can some post pic or video of what I need to modify for 1.75mm to work?

    I hear 2 things from this thread, the tube size and old part v1?

    it did work for me with a tube insert: od 3mm, id 2mm, just put it inside the original and let it stick out a bit so you can pull it out again.

    For me the spring filament clamp didn't work any more, the wheel didn't reach the filament enough.

    So I used the old clamp, opened it , and put an extra piece of plastic in between the split, so it stands out a little extra.

    old filament clamp

     

    I must say that I didn't use it for a longer time yet, and I didn't use retraction, so there is no gaurantee...

     

    Scott did a video:

    What is this bronze thing on hot end? And what is purpose for?

    Thanks in advance

      • 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 5.3.0-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.
