Holes and open boundaries
Find open boundary signals before claiming an STL file is watertight.
Open boundary edges can point to holes or non-watertight shells. The tool detects those edges and keeps hole filling report-only.
- Open boundary edge count
- Watertight risk copy
- No guaranteed hole fill promise

Upload an STL to check open-boundary hole signals
Look for open boundaries, duplicate faces, degenerate triangles, and normals before deciding how to repair holes.

Hole repair starts with boundary detection
The page helps users interpret possible hole signals and understand which separate repairs are safe in the current workflow.
- Count open boundary edges as a signal for non-watertight models.
- Avoid saying the model is fixed when only an open-boundary signal is detected.
- Pair safe cleanup with a clear manual-review recommendation.

Hole filling is report-only
The tool can detect open-boundary hole risk and run separate safe cleanup, but it does not fill holes in the current workflow.

常见问题
下次打印前需要了解的问题
How does the tool find holes in an STL file?
It counts open boundary edges. These edges often indicate holes, shell gaps, or a non-watertight STL model.
Does duplicate face cleanup fix holes?
No. Duplicate cleanup can reduce mesh noise, but actual hole filling may require manual or specialized repair.
What does watertight mean for STL files?
A watertight STL has a closed surface with no open boundary edges. The checker reports boundary risk but does not guarantee printability.
