ABS

Acrylonitrile Butadiene Styrene

Classic engineering plastic — heat-resistant and tough, but needs an enclosure to control warping.

ABS is the workhorse engineering plastic of the 20th century — LEGO bricks, car trim, appliance housings — prized for toughness and machinability, commercialized by Borg-Warner in 1954.

In FDM it was the original durable filament, predating PLA's dominance, but its warping and styrene fumes pushed many users toward PETG and ASA.

Strengths & trade-offs

  • Tough and impact-resistant
  • Higher heat resistance (~100 °C)
  • Machinable, sandable, drillable
  • Acetone-vapor smoothable
  • Durable engineering material
  • Warps badly — needs heated bed + enclosure
  • Emits styrene fumes (ventilation needed)
  • Poor UV / weather resistance
  • Not biodegradable
  • Sensitive to drafts

Did you know

  • LEGO bricks are injection-molded ABS — the same polymer family in your spool.
  • ABS can be vapor-smoothed with acetone to a glossy, injection-molded-looking finish.
  • ABS was one of the first FDM filaments, developed for early Stratasys machines.
