PLA vs Nylon PA6

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

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

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

PLA Strengths

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

Nylon PA6 Strengths

  • Exceptional strength, very strong layer bonding, flexible and durable
  • High heat tolerance; low friction for mechanisms

Considerations

PLA Caveats

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

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

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