Strengths Comparison
PCTG Strengths
- Tough, strong layer adhesion, minimal warping/sagging
- Lower moisture uptake vs PETG; very easy printing for performance level
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Considerations
PCTG Caveats
- Supports can be hard to remove
- Expensive and harder to find
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 PCTG or PLA better for 3D printing?
PCTG is generally rated higher (Tier S) compared to PLA (Tier A). However, the best choice depends on your specific needs: PCTG is best for Tough, strong layer adhesion, minimal warping/sagging, while PLA is best for Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal.
What are the temperature differences between PCTG and PLA?
PCTG prints at 230-260°C nozzle / 70-85°C bed. PLA prints at 185-235°C nozzle / 50-60°C bed.
Do PCTG and PLA need an enclosure?
PCTG: optional. PLA: not needed.
Which is more beginner-friendly: PCTG or PLA?
Both PCTG and PLA are beginner-friendly options.
