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.

Green marks the category leader. PLA wins ease, cost, and fumes. ABS wins heat and rigidity.

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.

Frequently asked

Which is better, PLA or ABS?
It depends. PLA is better for easy, cool, low-cost prints. ABS is better for heat and rigidity. Match the filament to the job.
Is ABS stronger than PLA?
Yes. ABS is tougher, less brittle, and holds up to heat and impact. PLA is more rigid but snaps under sharp load.
Is PLA easier than ABS?
Yes, by a wide margin. PLA prints cool with no enclosure. ABS needs a hot bed, an enclosure, and ventilation.
Which is better for a part in a hot car?
ABS. PLA softens near 60 °C and warps in a hot car. ABS holds its shape in warmth.
