Strengths Comparison
Glass-filled Polypropylene Strengths
- Very tough, durable, all-weather, extremely lightweight
- Industrial-relevant material properties
PETG Strengths
- Tougher than PLA, higher temp tolerance, more durable in real-world use
- Good clarity and low friction among easy-to-print materials
Considerations
Glass-filled Polypropylene Caveats
- Even harder to print than PP; peels/curls more aggressively
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
