PCL vs ASA
Compare PCL and ASA 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
ASA
AAcrylonitrile Styrene Acrylate
Excellent UV resistance (outdoors indefinitely), tough, matte surface

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
ASA Strengths
- Excellent UV resistance (outdoors indefinitely), tough, matte surface
- Less warping than ABS; low viscosity enables very high speed printing
- High heat tolerance (~boiling water range)
Considerations
PCL Caveats
- Not actually PLA despite branding
- Low-temp / waxy nature limits use cases; poor adhesion for many glues
ASA Caveats
- Still off-gasses; enclosure/ventilation recommended
- Can still warp; needs tuning
Frequently Asked Questions
Is PCL or ASA better for 3D printing?
ASA 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 ASA is best for Excellent UV resistance (outdoors indefinitely), tough, matte surface.
What are the temperature differences between PCL and ASA?
PCL prints at 60-110°C nozzle / 30-45°C bed. ASA prints at 220-275°C nozzle / 90-110°C bed.
Do PCL and ASA need an enclosure?
PCL: not needed. ASA: recommended.
Which is more beginner-friendly: PCL or ASA?
PCL is more beginner-friendly as it doesn't require an enclosure.
