ABS: full cost overview

ABS is the engineering plastic of Lego bricks and automotive trim. Tough, heat-resistant to ~95 °C, machinable and solvent-weldable. Demands an enclosed chamber to avoid warping, ventilates VOCs while printing and shouldn't run in a closed bedroom. Worth the trouble when you need real mechanical durability.

Specs

Typical price: ~$22.00/kg
Print temperature: 230–260 °C
Bed temperature: 100–110 °C
Enclosed chamber: Recommended
Food-safe: No
Difficulty: ★★★★☆

When to use

• Functional parts under mechanical stress
• Parts that go in cars or near heat sources
• Items you'll acetone-vapor smooth
• Lego-like snap-fit prototypes

When NOT to use

• Open-frame printer without enclosure
• Closed bedroom without ventilation
• Food contact applications
• Parts exposed to sunlight (use ASA)

How to print well in ABS

ABS demands an enclosed chamber — an open frame results in severe warping and layer delamination. Nozzle 230-260 °C, bed 100-110 °C, passive enclosure (P1S, X1C) reaches ~50 °C; an actively heated chamber (H2D) reaches 65 °C and unlocks large parts. Low cooling: fan 0-30% after the first layer. Bed adhesion: PVA glue or Magigoo ABS works well; glass beds and flexible PEI hold better than smooth steel sheets. Ventilation is non-negotiable: ABS releases VOCs during printing — don't run it in an unventilated room. For a glass-smooth finish, acetone vapor smoothing is the classic technique — the part comes out looking molded.

Typical cost in practice

ABS in the US runs $20-28/kg from Hatchbox, eSun and Polymaker, and $32-42/kg in premium grades (Polymaker PolyLite ABS Pro). For an 80 g functional part, filament cost is $1.60-2.20 — similar to PETG but with real advantages in heat resistance (~95 °C before softening) and the option of solvent-smoothing. Makes sense for automotive parts (brackets, jigs under heat), household items near heat sources (kitchen, BBQ) and functional cosplay. Doesn't pay off if you only have an Ender 3 or A1 without an enclosure — the material is the easy part, the setup is the expensive part.
