PCTG vs PLA
Compare PCTG and PLA filaments side-by-side so you can pick the right one for your 3D printing project.
PCTG vs PLA: PCTG is known for tough, while PLA is known for easiest to print. PLA is easier to print; PCTG prints at higher nozzle temperatures (230-260°C vs 190-220°C). Choose PCTG for tough, or PLA for easiest to print.
Key differences at a glance
PCTG
SPolycyclohexylene Dimethylene Terephthalate Glycol-modified
Tough, strong layer adhesion, minimal warping/sagging
PLA
APolylactic Acid
Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
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
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
