Nylon PA6 vs Polycarbonate

Compare Nylon PA6 and Polycarbonate filaments side-by-side so you can pick the right one for your 3D printing project.

Nylon PA6 vs Polycarbonate: Nylon PA6 is known for exceptional strength, while Polycarbonate is known for very tough and stiff. Both have required enclosure requirements; Polycarbonate is less moisture-sensitive; Polycarbonate prints at higher nozzle temperatures (260-310°C vs 240-290°C). Choose Nylon PA6 for exceptional strength, or Polycarbonate for very tough and stiff.

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

Polycarbonate Strengths

  • Very tough and stiff; doesn't shatter like PLA
  • High heat resistance (~150C softening region)

Considerations

Nylon PA6 Caveats

  • Extremely hygroscopic; can waterlog during a print
  • Warps strongly; can pull plates off beds
  • Over-drying can make it brittle

Polycarbonate Caveats

  • Often overkill and high effort for typical use

Frequently Asked Questions

What is the difference between Nylon PA6 and Polycarbonate?
Nylon PA6 prints at 240-290°C nozzle / 70-110°C bed (Required enclosure, very high moisture sensitivity). Polycarbonate prints at 260-310°C nozzle / 90-120°C bed (Required enclosure, high moisture sensitivity).
Is Nylon PA6 or Polycarbonate stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Nylon PA6 is suited to exceptional strength, while Polycarbonate is suited to very tough and stiff.
Which prints at a higher temperature, Nylon PA6 or Polycarbonate?
Polycarbonate prints at a higher temperature (260-310°C nozzle vs 240-290°C for Nylon PA6).
Is Nylon PA6 or Polycarbonate better for beginners?
Polycarbonate is better for beginners: enclosure is required and moisture sensitivity is high, vs required enclosure and very high moisture for Nylon PA6.
Should I use Nylon PA6 or Polycarbonate for flexible parts?
For flexible parts, Nylon PA6 is usually the better fit (Exceptional strength). Choose Polycarbonate instead when very tough and stiff.
