Lead time: 5 days Cost reduction: 38% First-pass fit

1. Problem

The client needed a replacement for a discontinued mirror bracket. No CAD model or drawing existed, and vehicle downtime had to be minimized.

2. Constraints

  • Only one worn physical sample was available
  • Critical mounting interfaces required accurate fit
  • Outdoor temperature and vibration resistance needed
  • Delivery deadline under 7 calendar days
  • Budget lower than machining a one-off part

3. Process / Material Chosen

We combined 3D scanning, CAD reconstruction, and rapid iteration to restore geometry and validate assembly before delivery.

Selected process and material

FDM with carbon-fiber reinforced nylon was selected for strength, thermal stability, and practical turnaround.

Execution steps

  1. Scan original sample and clean mesh data
  2. Rebuild parametric CAD with corrected wear zones
  3. Print and test revision A on assembly
  4. Release final revision and deliver production files

4. Outcome (Time, Cost, Quality)

The part was installed without post-processing and met functional expectations in normal service conditions.

Time5 days from sample receipt to installed part
Cost38% lower than machining quote for low volume
QualityNo rework required during first installation
  • Repeatable dimensional fit on critical holes and slots
  • Improved rib geometry for longer service life
  • Reusable CAD baseline for future batches
