- Export the .STL file in your 3D modeling software of choice
- Run your model through the naked edges test (instructions below) in Rhino and make sure there are no naked edges:
- Select your entire model and then go to the "Analyze" menu on the toolbar, then click on "EdgeTools", then "Show Edges"
- Select "Naked Edges" and confirm that nothing gets highlighted.
- If there are highlighted lines please fix these before coming to the desk, as we will not print any files containing naked edges
If using 3DS Max utilize the "STL Check" Modifier to check for model watertightness. Watertightness is a property of a mesh that has no holes or naked edges, and thus would not theoretically admit any water or fluid.
