ABS vs PETG
Compare ABS and PETG filaments side-by-side so you can pick the right one for your 3D printing project.
ABS
CAcrylonitrile Butadiene Styrene
Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use

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
ABS Strengths
- Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance
- Good impact toughness for the price
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
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)
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
Frequently Asked Questions
Is ABS or PETG 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: ABS is best for Fast printing, acetone soluble (weld/vapor smooth), cheap, tough, decent heat resistance, while PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use.
What are the temperature differences between ABS and PETG?
ABS prints at 230-255°C nozzle / 95-110°C bed. PETG prints at 230-250°C nozzle / 70-90°C bed.
Do ABS and PETG need an enclosure?
ABS: recommended. PETG: optional.
Which is more beginner-friendly: ABS or PETG?
PETG is more beginner-friendly as it doesn't require an enclosure.
