Cura 5.2.1. Precision placement of seperate models.

Posted (edited) · Cura 5.2.1. Precision placement of seperate models.

Using cura 5.2.1 I'd like to have 2 separate models placed overlapping in a very precise way.



On the left we see a single model (exported as a single STL) that is what I need to end up with.
In the middle we have part of a disk that should be placed overlapping to the teeth model on the right.
The end result should be just like the model on the left.


Reason being is that I am printing functional parts and the middle disk part and the teeth part have different print settings.


The problem I have is that cura automatically drops the models on the build plate (even when disabling that feature in the general settings) and the orientation of the models in relationship to each other is lost during importing.
If the orientation would be preserved, even though models end up on the build plate (basically overlapping during multiple model import) I am already helped a lot because then I could simply adjust the z axis on the disk model.

It is getting the models aligned in terms of orientation that has me struggeling at the moment.


Please find attached my cura project file.

Does anyone have a suggestion on how to do this?

    Hey @printnewb,


    There is a special button for that in Cura!
    If you select both models | Right Click | Merge Models.
    If you exported your models correctly, which you did, they will remember the position they had in CAD.



    If this wouldn't have worked you can doublecheck your preferences.

    Preferences | Configure Cura.

    There is two boxes to you can uncheck

    1. Keep models apart
    2. Automatically drop models to the buildplate


    Hope this helps 😊

    thank you for this illuminating response.


    I happened to come across it though only by chance. Somehow I am not receiving emails when responses are in.


    Is there a forum setting I have overlooked or is there a known issue with notifications at the moment?

      • 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.
