Scan & reverse engineering · for Neufeld
Spare part from a scan: engine‑bay fan shroud
Broken, no drawing, no replacement available – scanned, redesigned as a CAD model and printed with glass-fibre reinforcement.
- Service
- 3D scanning, reverse engineering, CAD, printing
- Scan
- Photogrammetry from 238 photos
- Size
- Ring Ø 484 mm
- Deviation
- Scan ↔ CAD median 0.44 mm (each fragment fitted separately)
- Material
- Glass-fibre filament, additionally laminated with glass-fibre mat
For Neufeld, a broken plastic fan shroud had to be replaced. There was no drawing and no spare part available.
Approach
- 3D scan: The part was digitised from 238 photos using photogrammetry and scaled using a measured hole spacing.
- CAD: The scan was turned into a clean, parametric CAD model (STEP) – symmetrical, with real dimensions instead of warped fragments.
- Check: Comparing scan and model – with each broken piece aligned individually – shows a median deviation of 0.44 mm.
- Print: Glass-fibre-reinforced filament, additionally laminated with glass-fibre mat – for use in the engine bay.
The new part is installed and in use. With the CAD file it can be made again at any time.
