PCL vs PLA
Compare PCL and PLA 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
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal

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
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
PCL Caveats
- Not actually PLA despite branding
- Low-temp / waxy nature limits use cases; poor adhesion for many glues
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
Frequently Asked Questions
Is PCL or PLA better for 3D printing?
PLA 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 PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal.
What are the temperature differences between PCL and PLA?
PCL prints at 60-110°C nozzle / 30-45°C bed. PLA prints at 185-235°C nozzle / 50-60°C bed.
Do PCL and PLA need an enclosure?
PCL: not needed. PLA: not needed.
Which is more beginner-friendly: PCL or PLA?
Both PCL and PLA are beginner-friendly options.
