Nylon PA6 vs Nylon PA12
Compare Nylon PA6 and Nylon PA12 filaments side-by-side so you can pick the right one for your 3D printing project.
Nylon PA6 vs Nylon PA12: Nylon PA6 is known for exceptional strength, while Nylon PA12 is known for absorbs far less moisture than pa6 (~0.3% vs ~3%). Nylon PA12 is easier to print; Nylon PA6 prints at higher nozzle temperatures (240-290°C vs 240-270°C). Choose Nylon PA6 for exceptional strength, or Nylon PA12 for absorbs far less moisture than pa6 (~0.3% vs ~3%).
Key differences at a glance
Nylon PA6
BPolyamide 6
Exceptional strength, very strong layer bonding, flexible and durable
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
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 PA6 Strengths
- Exceptional strength, very strong layer bonding, flexible and durable
- High heat tolerance; low friction for mechanisms
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
Considerations
Nylon PA6 Caveats
- Extremely hygroscopic; can waterlog during a print
- Warps strongly; can pull plates off beds
- Over-drying can make it brittle
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
