PETG vs ABS
Compare PETG and ABS filaments side-by-side so you can pick the right one for your 3D printing project.
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use
ABS
CAcrylonitrile 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
Is PETG or ABS better for 3D printing?
PETG is generally rated higher (Tier A) compared to ABS (Tier C). However, the best choice depends on your specific needs: PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use, while ABS is best for Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance.
What are the temperature differences between PETG and ABS?
PETG prints at 230-250°C nozzle / 70-90°C bed. ABS prints at 230-255°C nozzle / 95-110°C bed.
Do PETG and ABS need an enclosure?
PETG: optional. ABS: recommended.
Which is more beginner-friendly: PETG or ABS?
PETG is more beginner-friendly as it doesn't require an enclosure.
