Nylon PA12 vs PETG
Compare Nylon PA12 and PETG filaments side-by-side so you can pick the right one for your 3D printing project.
Nylon PA12 vs PETG: Nylon PA12 is known for absorbs far less moisture than pa6 (~0.3% vs ~3%), while PETG is known for tougher than pla. PETG is easier to print; Nylon PA12 prints at higher nozzle temperatures (240-270°C vs 230-250°C). Choose Nylon PA12 for absorbs far less moisture than pa6 (~0.3% vs ~3%), or PETG for tougher than pla.
Key differences at a glance
Nylon PA12
BPolyamide 12
Absorbs far less moisture than PA6 (~0.3% vs ~3%), so it holds dimensions in humid air and is much more forgiving to print
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
Nylon PA12 Strengths
- Absorbs far less moisture than PA6 (~0.3% vs ~3%), so it holds dimensions in humid air and is much more forgiving to print
- Tougher and more impact resistant than PA6, especially in the cold; good chemical and abrasion resistance
- Good for tubing, clips, connectors and flexible mechanical parts
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
Nylon PA12 Caveats
- Less stiff than PA6 (flexural modulus roughly 1.4-1.5 GPa vs 2.8-3.0 GPa)
- Lower heat resistance than PA6; melts around 178C rather than 220C
- More expensive than PA6
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
