Glass-filled Polypropylene vs PETG
Compare Glass-filled Polypropylene and PETG filaments side-by-side so you can pick the right one for your 3D printing project.
Glass-filled Polypropylene vs PETG: Glass-filled Polypropylene is known for very tough, while PETG is known for tougher than pla. PETG is easier to print; Glass-filled Polypropylene is less moisture-sensitive; Glass-filled Polypropylene prints at higher nozzle temperatures (230-260°C vs 230-250°C). Choose Glass-filled Polypropylene for very tough, or PETG for tougher than pla.
Key differences at a glance
Glass-filled Polypropylene
BGFPP / PP-GF
Very tough, durable, all-weather, extremely lightweight
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use
Detailed Comparison
Green marks the generally easier or more forgiving option in that row, based on tier, enclosure needs, and moisture sensitivity. It is not always the better choice for a specific job, so weigh it against what your project actually needs.
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
