ABS Print Settings
Expert-recommended ABS (ABS) settings for all Bambu Lab printers
Why use ABS?
- High heat resistance (up to ~100°C) for automotive and electronic enclosures
- Excellent impact resistance and toughness
- Can be smoothed with acetone vapor for glossy finish
- Industry-standard engineering thermoplastic
- Good for functional mechanical parts with snap-fit features
- Lower material cost than specialty engineering filaments
What are the best ABS print settings?
Use default Bambu Lab temperature profiles for ABS. Recommended outer wall speed is 150 mm/s.
| Setting | Value | Note |
|---|---|---|
| speed.layers.outerWall | 150 | Slower to prevent warping and improve adhesion |
| speed.layers.innerWall | 250 | Moderate inner wall speed |
| speed.layers.sparseInfill | 400 | Reduced infill speed for ABS |
| speed.initial.layer | 30 | Very slow first layer critical for ABS adhesion |
| others.bed.brimType | Outer and inner brim | Essential — ABS warps heavily without brim |
| support.filament.interface | HIPS | Dissolvable in limonene for clean interface separation |
| support.filament.base | Same as model | ABS as bulk support — thermally compatible |
| others.bed.brimWidth | 8 | Wide brim for warping prevention |
| quality.seam.position | Back | Hide seams on ABS parts |
| quality.precision.elephantFootCompensation | 0.2 | ABS squishes more on heated bed |
| support.thresholdAngle | 35 | ABS benefits from more support |
| quality.advanced.avoidCrossingWall | true | Reduces stringing on ABS |
What nozzle size should I use for ABS?
0.4mm — fine ABS requires careful temperature control
0.4mm standard nozzle
0.6mm for fast ABS parts — less warping risk with faster prints
How do I dry ABS filament?
Dry ABS at 70°C for 4-6 hours. Moderate moisture absorption
What support material should I use with ABS?
Recommended: ABS base + HIPS interface
Base: Same as model (ABS) | Interface: HIPS (dissolvable in limonene)
ABS as bulk support with HIPS only at the interface. HIPS dissolves in limonene for clean separation without damaging the model. PVA cannot be used — temperature too high.
~30% less HIPS filament used
Expert Tips for ABS
- ENCLOSURE IS MANDATORY. ABS warps severely in open air. H2D's enclosure handles this natively.
- A1 is NOT recommended for ABS — no enclosure means guaranteed warping on larger prints.
- Use a brim (8mm+ width) and consider a raft for large flat parts.
- Acetone vapor smoothing gives ABS a glass-like finish — a unique advantage over other materials.
- Print with bed at 100-110°C and keep enclosure closed during the entire print.
Which Bambu Lab printers work with ABS?
Use with caution on: P1P, A1, A1 Mini, Ender 3 V3 SE
Alternatives to ABS
If you need UV resistance for outdoor parts — ASA is "ABS but better outdoors"
Trade-offs: Similar warping challenges. Also needs enclosure for best results. Slightly higher cost
If you want to skip the enclosure requirement entirely while retaining toughness
Trade-offs: Lower heat resistance (~80°C vs ~100°C). Cannot be acetone-smoothed. More stringing during printing
If you need the highest impact and heat resistance (~130°C) for critical applications
Trade-offs: Most challenging material to print. H2D with enclosure mandatory. Severe warping
