This is text about how to import an STL.
Automatic Part Repairs
Repair mode can be entered by clicking the red cross in the top tool ribbon. From repair mode there are several fields of significant importance; shells, border edges, invalid orientations, and holes. These are all technical issues with the STL and are not functions of your part. There should be 1 shell per continuous part, 0 border edges, 0 invalid orientations, and 0 holes.
- Netfabb's automatic repair tools can be used to fix these problems in most scenarios:
Automatic Repairin the lower part of the Netfabb part tree.
- Click either
Simple Repair. *This may take some time to complete
- If your part does not have 0 border edges, 0 invalid orientations, and 0 holes attempt another repair.
- If your part now has 0 border edges, 0 invalid orientations, and 0 holes click
Apply Repair. *Note:There are other tools to reduce shells to 1
It is not recommended that you use the extended repair. This repair wraps the visible surface of your STL in a new mesh. This repair can lead to thin regions of your model which is of particular concern if plan to use the zPrinter 450.
- In the event an automatic repair cannot merge your part down to 1 shell you may:
- Adjust your Rhino file so there is 1 closed polysurface per part before meshing or exporting as an STL.
- Mesh your model in Netfabb by importing the CAD file instead of an STL.
- Use Netfabb's boolean operations to reduce the mesh to 1 shell.
If the Boolean union command fails to merge down to one shell it is likely that the shells are disjointed and will print as separate parts.
- When repairs have been completed you will need to re-export your model as an STL:
- Select your model.
- Right Click
Export as STL
As a reminder, your STL must have 0 border edges, 0 invalid orientations, and 0 holes before exporting and should have 1 shell per continuous part, and 1 part per STL. Failure to follow these guidelines could result in a failed 3D print.
