Printing and design cautions
- Warping and layer splitting
- Ventilation needs increased attention
- Design for thermal movement.
- Verify the exact formulation for outdoor exposure.
Major limitations and safety notes
- Usually needs a controlled build environment.
- Not a universal food-contact or safety material.
Use normal good workshop practice and manufacturer safety information. This is generic guidance, not a hands-on spool review or a safety certification.
