How do I close holes / make solid an OBJ or STL file?

[BackstreetZAFU]

Hi Everyone,

I recently sent a sample model to Formlabs to have a test print done. However, they said that the model showed some holes and irregularities that could cause print deformities.

Is there a way to “seal” the model? Or make it solid? Something so that the holes don’t cause a problem anymore?

I feel like I used to use netfabb to do this, but I’ve tried redownloading it, and I can’t find a version that works with MAC.

If anyone has any advice, that would be hugely helpful.

Thank you!

I gave it a try, and it looks like it worked on my end. I’ll have to see if the file is good enough for them to print.

Thank you so much for the help!
