PCL vs PETG
Compare PCL and PETG filaments side-by-side so you can pick the right one for your 3D printing project.
PCL vs PETG: PCL is known for very low-temp printing (~100c), while PETG is known for tougher than pla. PCL is easier to print; PETG prints at higher nozzle temperatures (230-250°C vs 60-110°C). Choose PCL for very low-temp printing (~100c), or PETG for tougher than pla.
Key differences at a glance
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
Detailed Comparison
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
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
