ABS

ABS (Acrylonitrile Butadiene Styrene) is a thermoplastic with good heat stability and impact resistance. It requires an enclosure and is more demanding than PLA/PETG, but produces durable functional parts.

Settings

Parameter	Value
Nozzle temperature	240–260 °C
Bed temperature	90–110 °C
Chamber temperature	45–55 °C (X1C/P1S)
Part cooling	0–20%
Aux fan	0%
Speed	80–100%
Drying	Recommended (4–6 h at 70 °C)

Recommended build plates

Plate	Suitability	Glue stick?
Engineering Plate (Textured PEI)	Excellent	Yes (recommended)
High Temp Plate	Excellent	Yes
Cool Plate (Smooth PEI)	Avoid	—
Textured PEI	Good	Yes

:::tip Glue stick for ABS Always use glue stick on the Engineering Plate with ABS. It improves adhesion and makes it easier to release the print without damaging the plate. :::

Enclosure (chamber)

ABS requires a closed chamber to prevent warping:

• X1C and P1S: Built-in chamber with active heat management — ideal for ABS
• P1P: Partially open — add a top cover for better results
• A1 / A1 Mini: Open CoreXY — not recommended for ABS without a custom enclosure

Keep the chamber closed throughout the print. Don't open it to check the print — waiting until it cools down also prevents warping on release.

Warping

ABS is highly prone to warping (corners lifting):

• Increase bed temperature — try 105–110 °C
• Use brim — 5–10 mm brim in Bambu Studio
• Avoid drafts — close all air flows around the printer
• Lower part cooling to 0% — cooling causes warping

:::warning Fumes ABS emits styrene fumes during printing. Ensure good ventilation in the room, or use a HEPA/active carbon filter. The Bambu P1S has a built-in filter. :::

Post-processing

ABS can be sanded, painted, and glued more easily than PETG and PLA. It can also be vapor smoothed with acetone for a smooth surface — but be very careful with acetone exposure.

Storage

Dry at 70 °C for 4–6 hours before printing. Store in a sealed box — ABS absorbs moisture, which causes popping sounds and weak layers.
