Metal-filled PLA vs PETG

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

Metal-filled PLA vs PETG: Metal-filled PLA is known for hefty, while PETG is known for tougher than pla. Metal-filled PLA is easier to print; PETG prints at higher nozzle temperatures (230-250°C vs 190-220°C). Choose Metal-filled PLA for hefty, or PETG for tougher than pla.

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

Metal-filled PLA Strengths

  • Hefty, can show metal-like properties (patina/polish/magnetism)

PETG Strengths

  • Tougher than PLA, higher temp tolerance, more durable in real-world use
  • Good clarity and low friction among easy-to-print materials

Considerations

Metal-filled PLA Caveats

  • Weaker than regular PLA
  • Very brittle on/off spool
  • Very expensive and higher density means fewer prints per spool
  • Usually better replaced by paint/inserts/electroplating

PETG Caveats

  • Overhangs/bridges sag; supports can be hard to remove
  • Absorbs water fairly quickly

Frequently Asked Questions

What is the difference between Metal-filled PLA and PETG?
Metal-filled PLA prints at 190-220°C nozzle / 50-60°C bed (No enclosure, moderate moisture sensitivity). PETG prints at 230-250°C nozzle / 70-90°C bed (Optional enclosure, moderate moisture sensitivity).
Is Metal-filled PLA or PETG stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, Metal-filled PLA is suited to hefty, while PETG is suited to tougher than pla.
Which prints at a higher temperature, Metal-filled PLA or PETG?
PETG prints at a higher temperature (230-250°C nozzle vs 190-220°C for Metal-filled PLA).
Is Metal-filled PLA or PETG better for beginners?
Metal-filled PLA is better for beginners: enclosure is no and moisture sensitivity is moderate, vs optional enclosure and moderate moisture for PETG.
Should I use Metal-filled PLA or PETG for hefty?
For hefty, Metal-filled PLA is usually the better fit (Hefty). Choose PETG instead when tougher than pla.
