Cura is not strong, to many traingles?


Recommended Posts

Posted · Cura is not strong, to many traingles?

Hello everyone! 


For my final year we have a project to 3D print buildings so blind people are able to know how the building is formed. We take pictures with a drone and import these into Reality Capture, by this way we get a 3D model with a super thin layer of what the building looks like. We fill it up in Zbrush so it is printable. We import the STL from Zbrush in Cura, but Cura is not able to slice. We found there was a problem with the amount of triangles, our model consists of 21,000,000 traingles and Cura is only able to handle 1,000,000 traingles. So we are not able to 3D print it. 

Is there any solution for this?


Thanks in advance! 



The error code we got:

    Use less triangles 😉

    The model has more detail than the machine will ever be able to handle. There are various software packages out there that can simplify meshes.

      • 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.
