PLA vs ABS — settings & when to use which

A side-by-side of recommended print settings and practical trade-offs between PLA (Polylactic Acid) and ABS (Acrylonitrile Butadiene Styrene), from the manufacturer data this site is built on.

Settings are starting points. Ranges span every brand in the database; tune per spool with a temperature tower. See the per-brand tables on the PLA and ABS pages.

Choose PLA when…

  • Prototypes and visual models
  • Toys, figurines, miniatures
  • Indoor display pieces
  • Anything where heat resistance does not matter

Choose ABS when…

  • Durable indoor functional parts
  • Parts needing heat resistance
  • Acetone vapor-smoothed finishes

FAQ

Should I print in PLA or ABS?

PLA: The default beginner filament: prints cool, almost no warping, no enclosure needed. ABS: A durable, heat-resistant engineering plastic that can be acetone-smoothed — but it warps hard and emits fumes (styrene), so an enclosure and ventilation are effectively required. In short, PLA runs cooler (180–230 °C, no enclosure needed) and ABS runs hotter (230–270 °C, enclosure required).

Is ABS stronger than PLA?

PLA heat resistance: Low. Glass transition ~55–60 °C; unmodified PLA parts deform in a hot car or direct summer sun. ABS heat resistance: High. Glass transition ~100 °C — suitable for warm environments and under-hood-adjacent indoor parts.
