Strengths Comparison
PETG Strengths
- Tougher than PLA, higher temp tolerance, more durable in real-world use
- Good clarity and low friction among easy-to-print materials
Nylon PA6 Strengths
- Exceptional strength, very strong layer bonding, flexible and durable
- High heat tolerance; low friction for mechanisms
Considerations
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
Nylon PA6 Caveats
- Extremely hygroscopic; can waterlog during a print
- Warps strongly; can pull plates off beds
- Over-drying can make it brittle
Frequently Asked Questions
Is PETG or Nylon PA6 better for 3D printing?
PETG is generally rated higher (Tier A) compared to Nylon PA6 (Tier B). However, the best choice depends on your specific needs: PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use, while Nylon PA6 is best for Exceptional strength, very strong layer bonding, flexible and durable.
What are the temperature differences between PETG and Nylon PA6?
PETG prints at 215-270°C nozzle / 70-90°C bed. Nylon PA6 prints at 240-290°C nozzle / 70-110°C bed.
Do PETG and Nylon PA6 need an enclosure?
PETG: optional. Nylon PA6: required.
Which is more beginner-friendly: PETG or Nylon PA6?
PETG is more beginner-friendly as it doesn't require an enclosure.
