PCL vs PETG
Compare PCL and PETG filaments side-by-side. See which one is best for your 3D printing project.
PCL
BPolycaprolactone
Very low-temp printing (~100C); softens in warm water; can be heat-formed
PETG
APolyethylene Terephthalate Glycol-modified
Tougher than PLA, higher temp tolerance, more durable in real-world use

Strengths Comparison
PCL Strengths
- Very low-temp printing (~100C); softens in warm water; can be heat-formed
- Useful for prosthetics/fitment via hairdryer reshaping
- Can be used like an adhesive; similar to Shapelock/InstaMorph pellets
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
PCL Caveats
- Not actually PLA despite branding
- Low-temp / waxy nature limits use cases; poor adhesion for many glues
PETG Caveats
- Overhangs/bridges sag; supports can be hard to remove
- Absorbs water fairly quickly
Frequently Asked Questions
Is PCL or PETG better for 3D printing?
PETG is generally rated higher (Tier A) compared to PCL (Tier B). However, the best choice depends on your specific needs: PCL is best for Very low-temp printing (~100C); softens in warm water; can be heat-formed, while PETG is best for Tougher than PLA, higher temp tolerance, more durable in real-world use.
What are the temperature differences between PCL and PETG?
PCL prints at 60-110°C nozzle / 30-45°C bed. PETG prints at 215-270°C nozzle / 70-90°C bed.
Do PCL and PETG need an enclosure?
PCL: not needed. PETG: optional.
Which is more beginner-friendly: PCL or PETG?
Both PCL and PETG are beginner-friendly options.
