  Hi
  
  I export the mesh at Mechanical to STL file. The units that i use are mm but the STL file is in m. So i have to scale up x1000 the STL file at the 3d-printer. What is the problem? Any suggestion?

  It's probably a units clash in the stl export: the printer software should be able to deal with it.

  Hi
  
  I can not find any units clash in the stl export. The 3d slicer fails after the scaling

  I may not have been clear. You're running Mech in mm however some of the non-ANSYS export tools expect to be sent m: depending on the interaction you may find the model dimension is out by a factor of 1000: we often see the reverse from CAD where the design in mm is imported in m. Have you ever seen a mixing tank that is 9km high?
  
  I expect the exported stl is OK. Most segmentation software can cope with scaling, but I expect this must be done before slicing.
