PETG vs ABS

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

PETG vs ABS: PETG is known for tougher than pla, while ABS is known for fast printing. PETG is easier to print; ABS prints at higher nozzle temperatures (230-255°C vs 230-250°C). Choose PETG for tougher than pla, or ABS for fast printing.

PETG

A

Polyethylene Terephthalate Glycol-modified

Tougher than PLA, higher temp tolerance, more durable in real-world use

ABS

C

Acrylonitrile Butadiene Styrene

Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance

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

PETG Strengths

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

ABS Strengths

  • Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
  • Good impact toughness for the price

Considerations

PETG Caveats

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

ABS Caveats

  • Warps heavily
  • Strong fumes/off-gassing; enclosure plus ventilation recommended
  • Poor UV resistance; yellows and gets brittle outdoors (ASA is the better outdoor/UV choice)

Frequently Asked Questions

What is the difference between PETG and ABS?
PETG prints at 230-250°C nozzle / 70-90°C bed (Optional enclosure, moderate moisture sensitivity). ABS prints at 230-255°C nozzle / 95-110°C bed (Recommended enclosure, moderate moisture sensitivity).
Is PETG or ABS stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, PETG is suited to tougher than pla, while ABS is suited to fast printing.
Which prints at a higher temperature, PETG or ABS?
ABS prints at a higher temperature (230-255°C nozzle vs 230-250°C for PETG).
Is PETG or ABS better for beginners?
PETG is better for beginners: enclosure is optional and moisture sensitivity is moderate, vs recommended enclosure and moderate moisture for ABS.
Should I use PETG or ABS for high-temperature parts?
For high-temperature parts, ABS is usually the better fit (Fast printing). Choose PETG instead when tougher than pla.
