There is no single winner between PLA and ABS. Which is better depends on what the part does. PLA is better for ease and cost. ABS is better for heat and strength.
How they compare
The table maps where each one wins. PLA leads ease and cost. ABS leads heat and rigidity.
| Property | PLA | ABS |
|---|---|---|
| Ease of print | Easy | Hard |
| Heat resistance | Low | High |
| Rigidity | Medium | High |
| Cost | Low | Medium |
| Fumes | Low | Strong |
| Needs enclosure | No | Yes |
| Better for | Models, prototypes | Warm, functional parts |
When PLA is better
PLA is better when you want easy printing, crisp detail, and low cost. It prints at 200 to 220 °C with no enclosure, per the Prusament PLA datasheet. It is the right pick for models, miniatures, and prototypes that stay cool.
When ABS is better
ABS is better when the part faces heat or needs rigidity. The Polymaker PolyLite ABS sheet lists a nozzle of 245 to 265 °C and a bed of 90 to 100 °C. ABS also takes acetone smoothing and holds up to sustained warmth.
