Filament Calibration

🔧1. Recommended Print Parameters

These are the optimal temperature ranges for each material:

Filament Type Nozzle Temperature Bed Temperature Cooling Fan
PLA+ 180°C - 220°C 40°C - 60°C 100%
PETG 230°C - 240°C 70°C - 80°C 30% - 50%
ABS 230°C - 250°C 90°C - 110°C 0% (enclosure recommended)
Tip: Always start with the lowest temperature and increase gradually to find the best layer quality and adhesion.

🧪2. Essential Calibration Tests

  1. Temperature Tower: Print a tower with 5°C increments. Observe which section has the best surface finish and bridging.
  2. Flow Calibration: Use a flow test tower (e.g., 85% to 115%) and measure wall thickness to adjust extrusion multiplier.
  3. Retraction Test: Print models that induce stringing and tweak retraction distance and speed accordingly.
  4. Speed Test: Evaluate print quality and efficiency at different speeds to find the ideal compromise.
  5. Tolerance Test: Calibrate XY dimensional accuracy using press-fit or clearance fit models.
Why calibrate? Proper calibration helps avoid warping, stringing, poor layer adhesion, dimensional errors, and ensures reliable results across all projects.

🌡️3. Environmental Settings and Best Practices

  • PLA / PLA+: Fan 100%, bed 40°C - 60°C, store in a dry place.
  • PETG: Fan 30% - 50%, bed 70°C - 80°C, avoid drafts during printing.
  • ABS: Nozzle 230°C - 250°C, bed 90°C - 110°C, use an enclosure to avoid warping.
  • Humidity: Store filament in sealed bags with silica gel to avoid moisture issues.
Tip: If your filament crackles while printing, it has absorbed moisture. Dry it before use for best results.
