Hi jvalal,
in general, Shapeways should not have problems accepting overlapping triangles. There is probably some other issue occuring. Please proceed the following way:
- Download netfabb Studio Basic from
https://www.netfabb.com/download.php .
- Load your STL file. Select it by clicking onto it (it will become green)
- Click on the red cross, as seen in the picture
- Take a look at the statistics (probably click on "Update before"). It could look like:
- Trying auto-repair and other functionality should bring your model down to statistics like
- After repairing, click on "Apply Repair", and export the STL via the context menu in the tree:
- And now comes the last and the most crucial step. The STL format has some disadvantages in saving some model situations that occur quite often. Even if your file is 100% correct, saving it as STL will recreate some errors. If that could happen, then there opens a dialog which alters the mesh slightly to prevent this. Just click onto "repair" as long as the statistics show
- A final click on "export" will guide you through it.
I have created dozens of STL-files for an upload to Shapeways and not even one has been rejected from their tool-chain.
If you need some more tricks how to get your model fixed, just ask. Or post some screenshots of your mesh statistics
Bye,
Alex
