Issue with infill filling an open area.
Hello,
I am trying to print a part similar to a cup. When I slice the file the open area of the "cup" gets filled with infill.
I have tried to change the infill to zero, but then the walls look too thin. Any ideas on what the problem might be?
Thank you.

try increasing the number of perimeters!

Ok, I will try that. Thank you.

I increased the perimeters and it didn't help. I did notice something weird with the file though. It appears to be split near the bottom.
Here is what it looks like pre-slice:

After being sliced:

Any idea what is causing this? I can slice it ok vertically:

With the infill:

Thank you.
RE: Issue with infill filling an open area.
The model is likely damaged, with errors. That’s the usual cause of slice errors. If you are in windows 10 you can right click the model and use the fix through netfabb option. That often fixes things but doesn’t always.
If you post the model we can look at it. Zip it up to attach it to the forum.

It looks like you are correct about the file having issues. I tried to use a "free" program to check it and it found disconnected parts or something. I wasn't able to get the repaired file back, the "free" program wanted to charge me to print it and ship it. That wouldn't be too bad, but it was based in Germany and shipping was way too much. I am working on trying to upload the file.
Thank you for the help.

Success! I created an account to use NetFabb and it appears to have fixed the problem.

PrusaSlicer comes with Netfabb and can repair an STL locally. Just run PSlicer, select File:Repair STL ... no Netfabb account required.

Freecad can also repair some things for free, and free to install on windows and Linux.
RE: Issue with infill filling an open area.
I've found that the stand-alone version of Netfabb will repair some wonky .stl files that Prusaslicer will not.
In addition to the 'fix it' menu that FreeCAD has under the Mesh workbench, I've found that simply importing the bad .stl into the Part workbench, then doing Convert Mesh to Shape -> Refine Shape -> Convert to Solid will fix many of the bad .stl files, particularly many of those done with OpenSCAD.
RE: Issue with infill filling an open area.
The did have errors when I first imported it, I forgot about that. I hit the repair option and it was "fixed" then would still infill the opening. Repairing it in Netfabb directly is what fixed it. Most of the time files are repaired ok within Slicer.
A while ago I had printed a box that for some reason would not render a corner in Slicer. I didn't notice until the print was done and messed up. I wonder if that file could have been fixed in Netfabb as well. I ended up printing a different box because I didn't know any better.
Thank you all again. I am fairly new to 3D printing.
