Don't open 3mf files from Paint3D


Recommended Posts

Posted · Don't open 3mf files from Paint3D



First of all, I'am a teenager teacher and TICs supervisor in a Primary and high school in Leioa, next Bilbao. We are new in the 3dPrinter world. And I'am looking for programs for work with 5-6 primary grades... I have shown that Paint3D is very easy and It perfect for our children. After done a little 3d objects and save as 3mf file, the cura doesn't open it... and I don't know why... I tray with preinstaled Paint3D objetc too... but nothing...

Any Idea?

I showed too, that Paint3D has a option to print, but you have to have the printer connected to teh computer and that is'nt our case.

    I have never tried to open 3mf files in Cura, so I'm not sure if this is supported (some one else will probably reply with more details)


    However, what you can always do is convert the 3mf into STL using 3D builder: https://www.microsoft.com/en-us/store/p/3d-builder/9wzdncrfj3t6


    Next, you can open the STL in Cura


    It's an extra step, but that should work.

    Doesn't Paint3D have an export option to save as STL-file? First save in the native format, so you don't lose the design. Then export to STL if that options exists.


    Otherwise, in addition to converting, you might also want to try other simple CAD programs? Maybe Tinkercad? I haven't tried it yet, but I heard that some schools use it. Maybe other programs too?


    For kids of +10y, you might try DesignSpark Mechanical. It is more technically oriented, but still very easy to learn. And there exist a lot of good tutorial videos.


    Google or Youtube for these programs, and watch a few demos, to see if they appeal to you, and to the kids.

    I tried it, and Cura opens your file without problems...

    ...but the 3D object is not little, it's extreme small - only 0.4mm - so it's a bit hard to locate on the screen.... :sunglass:


    Here is how it looks like, if i scale it up by 10000% or so...:

    Yours ideas and help are very useful, especially the last one :):)  Now I have to investigate how to save (or make) the objetc in paint3D bigger than that :)

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
