Non-manifold edges
Requires manual review or a dedicated topology repair tool.

Non-manifold STL diagnostics
Detect non-manifold STL edges before choosing a repair path.
Non-manifold topology can break prints and is often too risky for blind automatic repair. This workflow detects it and keeps the boundary explicit.
- Non-manifold edges are critical
- Report-only by default
- Safe fixes still apply to separate triangle noise

Upload an STL to check non-manifold edges
The checker counts edges shared by too many faces and separates them from safe cleanup candidates.

检查重点
Non-manifold intent without overclaiming
This page is written for users who specifically searched for non-manifold STL repair.
- Explain why non-manifold edges are more serious than duplicate faces.
- Show safe fixes that are independent from non-manifold repair.
- Tell users when a modeling tool or manual topology review is needed.

Non-manifold is report-only in V1
The current safe repair engine does not guarantee non-manifold repair. It reports the issue and avoids risky inferred geometry.
支持
- Detect non-manifold edge count
- Repair separate safe issue families
- Document skipped topology repair
仅报告
- Automatic non-manifold reconstruction
- Watertight guarantee
- Boolean cleanup or self-intersection repair
常见问题
下次打印前需要了解的问题
Can this tool repair non-manifold STL files?
It can detect non-manifold edges and repair separate safe issues, but non-manifold topology itself is report-only in V1.
Why not automatically fix non-manifold edges?
Those repairs often require guessing intended geometry. A blind fix can damage the model, so the tool keeps it explicit.
What should I do with a non-manifold report?
Use it to locate the risk, then repair the model in CAD or a mesh tool that can handle topology decisions manually.
