Nylon PA6 vs PLA

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

Nylon PA6 vs PLA: Nylon PA6 is known for exceptional strength, while PLA is known for easiest to print. PLA is easier to print; Nylon PA6 prints at higher nozzle temperatures (240-290°C vs 190-220°C). Choose Nylon PA6 for exceptional strength, or PLA for easiest to print.

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

PLA Strengths

  • Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
  • Stiff non-composite thermoplastic, good tensile strength

Considerations

Nylon PA6 Caveats

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

PLA Caveats

  • Creeps under sustained load
  • Poor heat resistance, UV degradation, can shatter on drops
  • Not great for sanding/gluing/painting/touch-ups

Frequently Asked Questions

What is the difference between Nylon PA6 and PLA?
Nylon PA6 prints at 240-290°C nozzle / 70-110°C bed (Required enclosure, very high moisture sensitivity). PLA prints at 190-220°C nozzle / 50-60°C bed (No enclosure, moderate moisture sensitivity).
Is Nylon PA6 or PLA stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Nylon PA6 is suited to exceptional strength, while PLA is suited to easiest to print.
Which prints at a higher temperature, Nylon PA6 or PLA?
Nylon PA6 prints at a higher temperature (240-290°C nozzle vs 190-220°C for PLA).
Is Nylon PA6 or PLA better for beginners?
PLA is better for beginners: enclosure is no and moisture sensitivity is moderate, vs required enclosure and very high moisture for Nylon PA6.
Should I use Nylon PA6 or PLA for flexible parts?
For flexible parts, Nylon PA6 is usually the better fit (Exceptional strength). Choose PLA instead when easiest to print.
