Glass-filled Polypropylene vs PLA
Compare Glass-filled Polypropylene and PLA filaments side-by-side so you can pick the right one for your 3D printing project.
Glass-filled Polypropylene vs PLA: Glass-filled Polypropylene is known for very tough, while PLA is known for easiest to print. PLA is easier to print; Glass-filled Polypropylene is less moisture-sensitive; Glass-filled Polypropylene prints at higher nozzle temperatures (230-260°C vs 190-220°C). Choose Glass-filled Polypropylene for very tough, or PLA for easiest to print.
Key differences at a glance
Glass-filled Polypropylene
BGFPP / PP-GF
Very tough, durable, all-weather, extremely lightweight
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
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
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
Glass-filled Polypropylene Caveats
- Even harder to print than PP; peels/curls more aggressively
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
