PETG vs ABS
Compare PETG and ABS filaments side-by-side. See which one is best 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

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
- Outdoor capable for years (not fully UV proof but long-lasting)
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 recommended
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 215-270°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.
