Warping out of control (UM3E)


Recommended Posts

Posted (edited) · Warping out of control (UM3E)



we have big problems with warping and im a bit lost how to handle it.


I did a test print as an example to show our problems (Ignore the missing top layer I ran out of filament).
What i totally don't understand is the bent/crooked left site of the print over the support.

Is this only a warping artifact?


I tried to change bed temperature, initial layer flow, ambient temperature and wall line count but so far nothing really helped.

How can we improve our prints?

    Please give us more information. Which material, which bed temp, print temp, layer height, what do you du for bed adhesion, just glass, glue, spray, adhesion sheets, etc.

    Material: PLA
    Print temperature: 185°C (Initial layer: 190°C)
    Bed temperature: 70°C
    Layer height: 0.15mm
    Flow: 90% (Initial layer: 75% since the auto bed level results in a quite thin nozzle to bed distance)
    Speed: 70mm/s
    Other settings should be like the default 1.5mm PLA profile shipped with Cura

    We actually print directly on glass without adhesion sheets or anything because the print itself holds very well on glass. Directly after a print it is nearly impossible to get it off, we need to wait until the bed cools down so I thing in general adhesion is not a problem, only warping. We tried using adhesion sheets once which results in buying a new build plate since we could not get the print off.

    On the first sight, your bed temperature is too high with 70° for PLA so it could be that the PLA deforms due to too high temperature. Try lowering it to 60 or 55°.

    I would suggest..


    Set 1st layer bed temp to no more than 65, even try 60; 2nd and subsequent layers set bed temp to 50, certainly < 60

    You do not say but set 1st layer layer height to 0.3

    You do not say but set 1st layer print speed to 20 mm/s

    For the moment I would set print speeds to 40mm/s or lower.

    If you must print at 70 then set No. of slower layers to say 5;set Regular fan speed at layer  to say 6

    I set my 1st layer flow to 70 and then increase it 10% each layer to get to 100%

    Use a brim

    … if you start getting adhesion problems then either spread PVA or spray hairspray

      • 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.
