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.
