Food-contact or medical prototype use must be based on verified material documentation and the actual jurisdiction. A normal 3D-printing filament is not automatically food-safe or biocompatible.
Clarify the application
- Contact duration.
- Temperature.
- Cleaning.
- Regulatory requirement.
Material evidence
Request food-contact or biocompatibility documentation only when it exists. Layer voids, nozzle residue and post-processing can change suitability.
Prototype versus final
- Visual model.
- Functional test.
- Regulated product.
- Clinical use.
| Use | Prototype | Final product |
|---|---|---|
| Shape | PLA/PETG | Verify |
| Water contact | PETG/PP-like | Documents |
| Medical | Prototype only | Specialist review |
| High heat | Heat-resistant | Test |
Common engineering mistakes
- Assuming all PLA is safe.
- Ignoring layer porosity.
- Using unverified pigments.
- Reusing a contaminated nozzle.
- Claiming medical approval.
Buyer checklist
- What contact occurs?
- What temperature?
- How is it cleaned?
- Is documentation available?
- Is specialist review required?
