STL is too small. Check units. This warning is triggered when any bounding box dimension of the STL is smaller than the base element size. Possible causes are: 1 - The STL file is too small. Make sure that the units for the STL are correct. 2 - A course mesh size is used. Try refining the mesh size.
This critical warning indicates that the STL file may be in the wrong units, or poor mesh settings were used.
STL file example??.stl could not be repaired.
By default, Netfabb Simulation attempts to repair non-manifold STL files using the default Netfabb repair script. This critical warning notes whenever this repair process fails.
More than 20 percent of the mesh was removed. Increase the mesh density, add support structures, and check the component(s) are oriented so as to maintain component-build plate contact.
At the beginning of each grouped powder bed layer, elements generated for that region during the mesh preview are activated. If the elements are not connected to the baseplate or to previously meshed component to prevent translation and rotation, the elements are considered erroneous as parts cannot be constructed completely detached from the material below, and these elements are removed from the simulation. If more than 20% of the mesh preview elements are removed from the simulation, this critical warning is issued, indicating that the STL has been oriented or supported poorly.
## percent of the mesh is unsupported. Increase the mesh density, add support structures, and check the component(s) are oriented so as to maintain component-build plate contact.
This error occurs when more than 1% of the original geometry volume is not meshed.
