ASA Print Settings
Expert-recommended ASA (ASA) settings for all Bambu Lab printers
Why use ASA?
- Superior UV resistance — ideal for outdoor parts that won't yellow or degrade
- Better weatherability than ABS for garden, automotive, and drone parts
- Similar mechanical properties to ABS with better chemical resistance
- Can be acetone-smoothed like ABS
- Lower warping tendency than ABS
- Excellent for automotive trim, outdoor enclosures, and garden fixtures
What are the best ASA print settings?
Use default Bambu Lab temperature profiles for ASA. Recommended outer wall speed is 150 mm/s.
| Setting | Value | Note |
|---|---|---|
| speed.layers.outerWall | 150 | Slower for ASA surface quality |
| speed.layers.innerWall | 250 | Moderate speed — ASA similar to ABS |
| speed.layers.sparseInfill | 400 | Reduced speed for ASA |
| speed.initial.layer | 35 | Slow first layer for adhesion |
| others.bed.brimType | Outer and inner brim | Brim helps with ASA warping |
| support.filament.interface | HIPS | Dissolvable in limonene — compatible with ASA temps |
| support.filament.base | Same as model | ASA as bulk support |
| others.bed.brimWidth | 6 | Medium brim — ASA warps less than ABS |
| quality.precision.elephantFootCompensation | 0.2 | Compensate for high bed temp squish |
| quality.advanced.avoidCrossingWall | true | Reduces stringing |
What nozzle size should I use for ASA?
0.4mm nozzle for detailed outdoor parts
0.4mm standard nozzle
0.6mm for fast outdoor functional parts
How do I dry ASA filament?
Dry ASA at 70°C for 4-6 hours. Moderate moisture absorption
What support material should I use with ASA?
Recommended: ASA base + HIPS interface
Base: Same as model (ASA) | Interface: HIPS (dissolvable in limonene)
ASA as bulk support with HIPS at the interface only. Saves expensive HIPS filament while maintaining dissolvable separation. PVA/PET support materials NOT compatible.
~30% less HIPS filament used
Expert Tips for ASA
- Enclosure recommended but ASA is more forgiving than ABS without one.
- The #1 reason to choose ASA over ABS: UV resistance for outdoor use.
- ASA fumes are less intense than ABS but still print in a ventilated area.
- A1 users should be cautious — large ASA parts may warp without enclosure.
Which Bambu Lab printers work with ASA?
Use with caution on: P1P, A1, A1 Mini, Ender 3 V3 SE
Alternatives to ASA
If you don't need UV resistance and want a more established material with wider support
Trade-offs: ABS yellows and degrades in sunlight. More warping than ASA. Stronger fumes
If you want outdoor durability without the enclosure requirement
Trade-offs: Lower heat resistance than ASA. Less UV-resistant than ASA. More stringing
If you need higher heat resistance (~130°C) and maximum impact strength
Trade-offs: Much harder to print than ASA. Worse warping. Not UV-resistant like ASA
