Exact diagnosis
Select an issue and Meshworthy takes you to the affected geometry.
Explainable STL repair
Repair STL files on Mac and see exactly what changed.
Find holes, non-manifold edges, flipped normals, self-intersections, and disconnected shells. Preview every proposed change before exporting a verified mesh.
Expected outcomeA repaired model you can inspect, compare, and trust.
Operation review
Checks included in this workflow.
Meshworthy shows the affected geometry, applies the selected constraints, and checks the exported result. Limitations remain visible when a result requires manual review.
Repair comparison
Compare before and after with changed regions and measured surface deviation.
Intent Guard
Protect real openings, sockets, text, and thin details before repair.
Verified export
The exported file is re-opened and checked before Meshworthy calls it complete.
Controlled operations
Review changes before applying them.
Each workflow identifies the affected geometry, applies relevant constraints, compares the result, and validates the exported file.
01Detect
→Locate the exact geometry and explain why it matters.
02Constrain
→Protect intent, scale, file semantics, and printer limits.
03Compare
→Preview measurable changes before applying them.
04Verify
Re-open the export and check every promised result.
Understand the problem
How to repair an STL file safely.
Use the seven-step checklist to diagnose topology, protect design intent, compare the change, and verify the exported file.
Product questions
About explainable stl repair.
Can Meshworthy repair an STL automatically?+
Yes. It proposes a repair, shows what changed, and rechecks the result. Difficult openings can be handled with focused manual tools.
Does repair always mean watertight?+
Watertightness is one requirement, but it does not confirm that the design remains correct. Meshworthy also checks whether intentional openings or fine features were altered.
Does it upload my model?+
No. Analysis and geometry processing run locally on your Mac.
Local model preparation
Know before you print.
Coming soon to the Mac App Store. At launch, diagnosis will be free; Pro will unlock repair and preparation for $19.99, once — never a subscription. Model processing stays local.
