Cura creates top layers within the model


Recommended Posts

Posted · Cura creates top layers within the model

For some reason the 4.13.1 seems to create top layers inside the model. This did not happen before the update. I am sure there is a setting that fixes it but I can' t find any. The layers just above the weird top is not connected to the faulty one but floats one layer above it.
I have not tried printing since it is a 3 day print that might turn out bad. 


Does anyone know what is going on?

    It is hard to know what we are looking at without seeing the model and your print settings, but I blame your model. It may not be "manifold", which confuses Cura.



    If you want a better diagnosis, please save a project and post a link to it here.

    I would be super happy if it was the model, but it is thoroughly checked. No errors. It happends to a few other models as well. Like there is a limit to the height of the model. But ill post the project file, and I am super thankful for any help 🙂

    "...but it is thoroughly checked. No errors."

    You should have a talk with your checker.

    From  https://formware.co/OnlineStlRepair:


    --> 0 Naked edges (?)
    --> 0 Planar holes (?)
    --> 0 Non-planar holes (?)
    --> 586098 Non-manifold edges (?)
    --> 390147 Inverted faces (?)
    --> 0 Degenerate faces (?)
    --> 780879 Duplicate faces (?)
    --> 0 Disjoint shells (?)
    -> Repairing: 100.00%
    ----- Repair completed in 39429ms ------
    -> Vertex count changed from 195368 to 196569 (+1201)
    -> Triangle count changed from 781464 to 393134 (-388330)


    After opening the file I checked the model with @ahoeben's Mesh Tools and the "not watertight" warning came up.  I exported the model as an STL file and uploaded it.  MS 3D Builder also noted defects in the model and was able to repair it (but the formware site gives a report).

    I've attached a repaired file.

      • 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.
