PLA / PLA CF – Print Settings for Bambu Lab 0.20

PLA / PLA-CF – Print Settings (Bambu Lab A1 | 0.20 mm Layer Height)

These print settings are practically tested and specifically optimized for standard PLA and PLA-CF on the Bambu Lab A1.

They are designed as solid baseline settings that already deliver very high print quality.
Fine tuning can — and should — be adjusted depending on the specific part and application.

These settings are intentionally configured slightly slower to achieve a cleaner surface finish, better layer adhesion, and overall higher print quality.
They provide a very strong starting point for producing reliable and professional results.

Key points (Bambu Lab A1 optimized):

• Layer height: minimum 0.20 mm
• Use moderate retraction settings to avoid stringing
• Ensure clean travel moves for consistent surface quality
• Print at steady, slightly reduced speeds for optimal layer bonding
• Infill and wall lines are the main parameters for controlling strength and weight

Temperature settings:

• Nozzle temperature: 230 °C (PLA & PLA-CF)
• Bed temperature:
  • First and second layer: 70 °C
  • All following layers: 65 °C

Filament & moisture:

All tests were performed under normal room conditions.

Drying the filament is recommended if you experience:

• excessive stringing
• rough surface quality
• weak layer adhesion

Moisture can negatively affect surface finish and layer bonding.

For PLA-CF, a hardened steel nozzle is strongly recommended due to the abrasive carbon fibers.

Wall thickness and number of wall lines are the most important parameters for controlling strength and stability — often more influential than infill alone.

Tested real-world settings – no theory, just reproducible results.
