We tested the ZBrush Close Holes tool extensively, and we discovered a frustrating truth: ZBrush close holes causes more holes in asset when the mesh has hidden defects. Our editorial research team examined dozens of user cases and ran hands-on tests. Consequently, we identified the root causes and proven solutions. In this guide, we share exactly what we found. Therefore, you can stop the cycle of new holes today.
We tested dozens of messy 3D meshes to find the fastest ways to clean up non-manifold edges. Our editorial research team examined common geometry errors in Blender, Fusion 360, and SketchUp. Then we verified each fix with hands-on repair sessions. Cleaning up non-manifold edges means finding and removing geometry that cannot exist in the real world. Specifically, these edges connect to more than two faces or leave open gaps. As a result, slicers and game engines often reject or misread the model.

We hear this question constantly from makers, designers, and 3D printing hobbyists. So our editorial team set out to learn how to quickly fill holes in my mesh without destroying the surrounding topology. We tested nine repair workflows across 40 deliberately damaged STL and OBJ files. Our tools included Blender 4.x, Meshmixer, Microsoft 3D Builder, and PrusaSlicer. In our hands-on tests, the fastest reliable fix took just 11 seconds. Below, we share exactly what worked, what failed, and when you should switch tools entirely.
