Top 5 Design Tips
- Maintain a uniform wall thickness throughout your parts design
- Thick wall design is prone to warp or other cosmetic issues
- 10% Increase in wall thickness will provide 33% more stiffness with most materials.
- Thick wall areas can sink, warp or contain voids resulting in undesired defects.
- Using ribs can help to reduce thick wall sections while still giving the part strength.
Check with the material supplier before designing your part.
