AdvancedABS
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.
