What does Cura do with 3mf files?


Recommended Posts

Posted · What does Cura do with 3mf files?

I'm quite confused about what Cura does with 3mf files.

When I open a 3mf file which only has the 3dmodel.model file but no cura settings (cube_stack.3mf) then it positions the two cubes as mentioned in the 3mf file

-> at 0,0,0 a 2x2x2 cube and one stacked directly on top (3mf_empty_settings.png)


When I create some printer settings and export a 3mf file without a model and move the exported settings to the empty Cura folder from the previous 3mf file (now cube_stack_with.3mf)

and load it into cura I get (3mf_with_settings.png) where the cubes are not at the correct position anymore. Shouldn't the 3dmodel.model file be the only one which stores the position of the models (maybe besides some offsets? ) Are there any offsets between models that I'm missing here?


Also in the 3mf_empty_settings.png I expected to see the name of the two models cube_bottom and cube_top as that information is also only in the 3dmodel.model file.


Thanks in advance for any pointers.

I'm using Linux and Cura 4.11.0

    Thanks for the comment. Interesting yeah I also figured out that it depends on whether I restart Cura sometimes or whether some previous settings are somehow saved in the cache or somewhere.

    Are you using 4.11.0 as well or a newer version of Cura?

    Yes I extracted it though to also be able to directly work with CuraEngine

      • 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.
