Cura error message

[BruceR 0]

Once I load a file into Cura but before I run the file through the slicer I get a message that says "model is not wateright and may not print properly. This is not my original model but one I down loaded from Cults 3D so I can't change it.  Anyone have any idea on what I can do to get the model to print?

Often it will print as is.  Look at it in preview mode to see what will be created - there may be large areas missing or holes filled in. But there are lots of things you can do to repair the mesh.

 

"Watertight" is the hardest for AI to repair as it means there is a hole in the skin of the model somewhere and computers are pretty stupid when it comes to realizing what a human really "meant".

 

Cura has an amazing plugin to test your model to see if something is wrong with it and can repair a very few of the many potential problems:
In the upper right corner of Cura click "marketplace" and make sure you are on the "plugins" tab and install "Mesh Tools".  Then restart Cura.  Now right click on your model, choose "mesh tools" and first choose
"check mesh", then "fix model normals" and "fix simple holes" to see if that helps.  Cura doesn't fix most issues so...

 

netfabb free repair service is here (you have to create a free account first):

Here's another service - drag and drop mesh repair service:

Some people recommend tinkercad - it's free - you import your stl into tinkercad and then export it to a new stl and tinkercad will fix many issues.
