Evaluate a filament sample with the same process and specifications used for production. Check diameter, print consistency, dimensions, properties, multiple batches and packaging before placing a bulk order.
Test plan
- Diameter and ovality.
- Print a reference model.
- Measure dimensions and surface.
- Compare mechanical properties.
Batch evidence
Ask for multiple batch records and define acceptance limits. One good sample does not prove series stability.
Commercial check
- Packaging.
- Lead time.
- Claim route.
- Change notification.
| Area | Sample check | Scaling risk |
|---|---|---|
| Diameter | Spread and ovality | Flow variation |
| Printing | Reference model | Profile mismatch |
| Property | Test coupon | Batch drift |
| Packaging | Packed sample | Transport damage |
Common engineering mistakes
- Testing only one spool.
- Using another printer profile.
- Ignoring batch data.
- No acceptance limits.
- Approving by appearance.
Buyer checklist
- Is the method defined?
- Are multiple batches tested?
- Are dimensions measured?
- Is packaging checked?
- Is the claim route written?
