Slicer says your model isn't watertight? Ferdelance welds vertices, removes bad triangles, caps holes, and aligns normals β and it's the only repair tool that keeps your Bambu Studio multi-color paint data intact.

Most repair services strip the paint data Bambu Studio stores on every triangle. Hours of AMS color painting β gone. Ferdelance repairs the geometry and puts your colors back exactly where they were.
Triangle-level color assignments, plate metadata, and Bambu Studio multi-part projects survive the repair untouched. Re-slice and print β no repainting.
Weld vertices β remove degenerate faces β split non-manifold edges β cap holes β align normals. Auto-retry tightens settings each pass until the mesh is watertight.
Your models are your business. Repairs run entirely on your machine β files are never uploaded to any server, ever.
Interactive 3D viewport highlights non-manifold edges in red and open holes in amber, so you know exactly what was wrong and what got fixed.
Selling on MakerWorld or Etsy? Queue dozens of 3MF/STL files, repair them all in one click, and download a ZIP with a CSV repair report.
A fast custom parser chews through 168K+ vertex Bambu multi-part files without choking β including sub-model files inside the 3MF archive.
No installs, no uploads, no CAD degree required.
Drag in any .3mf or .stl β including Bambu Studio multi-part, multi-color projects.
The pipeline runs up to 10 passes, tightening tolerances each time, until the mesh is fully watertight.
Export a repaired 3MF with your AMS colors and plate data intact, or a clean binary STL.
Start free. Go Pro when you're fixing files for customers.

No. The entire repair engine runs in your browser. Your models never leave your computer β we couldn't look at them if we wanted to. Great for commercial and client work.
Yes. Bambu Studio stores paint data as attributes on each triangle inside the 3MF. Ferdelance carries those attributes through every repair step and writes them back on export, along with plate metadata and multi-part sub-models.
Non-manifold edges, open holes, degenerate (zero-area) triangles, duplicate vertices, and inconsistent normals β the usual reasons a slicer reports βmodel is not watertightβ or produces broken walls.
Almost all β but not every one. Files with very large missing regions or self-intersecting geometry can be beyond automatic repair. When that happens the tool says so plainly, suggests stronger settings, and the failed attempt is not counted against your daily free repairs.
A small text note embedded in the file metadata (and the filename). It never touches your model's geometry or colors. Pro exports are completely clean.
The free plan is permanent: 3 repairs every day, forever, no card needed. Use them up and three more arrive the next day. The free trial is separate β it's for people who want Pro. You get full Pro access right away, and if you cancel from your account page within 3 days you won't be charged a cent.
