Identifying Problems with STL Files Step 1. To alleviate the search, this 3D printing STL file help tutorial shows you a few steps to help identify and correct some problems in your STL file. If you’re not sure what symptoms to look for or what tools to use, identifying these model inconsistencies can seem like searching for a needle in a haystack. Cura automatically compensates for some smaller errors, but larger errors may require alternative methods in order to print correctly.

Sometimes a model’s “shells” contain errors that conflict with the intended geometry of the model.

Are you dealing with a print that comes out surprisingly different than what you expected, despite having ruled out more typical problems like improper slicing profile or poor print bed adhesion? It’s possible that your STL file is to blame.
