PLA Print Settings Reference

Complete reference guide for PLA print settings. Use these as starting points and adjust based on your specific printer, filament brand, and part requirements.

Temperature Settings

Setting Range Standard Notes
Nozzle Temperature 190-220°C 205°C Start at 205°C, adjust for stringing or adhesion
First Layer Nozzle 200-220°C 210°C +5°C from printing temperature for better adhesion
Bed Temperature 50-70°C 60°C Higher for better adhesion, lower to save energy
First Layer Bed 60-70°C 65°C Slightly higher than printing temperature

Speed Settings

Setting Range Standard Notes
Print Speed 40-80 mm/s 60 mm/s Good balance of speed and quality
First Layer Speed 15-30 mm/s 20 mm/s Slow for optimal adhesion
Outer Wall Speed 30-50 mm/s 40 mm/s Slower for better surface quality
Inner Wall Speed 60-100 mm/s 80 mm/s Can be faster, not visible
Infill Speed 60-100 mm/s 80 mm/s Fast to save time
Travel Speed 100-200 mm/s 150 mm/s As fast as your printer allows

Retraction Settings

Direct Drive

Retraction Distance 0.5-1.0 mm
Retraction Speed 30-45 mm/s
Z-Hop Height 0.2-0.4 mm

Bowden

Retraction Distance 4-6 mm
Retraction Speed 40-60 mm/s
Z-Hop Height 0.2-0.4 mm

Cooling Settings

Setting Value Notes
Part Cooling Fan 100% Full cooling for PLA produces best results
First Layer Fan 0% No cooling on first layer for adhesion
Enable Above Layer Layer 2 Start cooling from second layer
Minimum Speed 10 seconds/layer Increases fan for small layers

Layer and Quality Settings

Setting Range Standard Notes
Layer Height 0.12-0.28 mm 0.20 mm 0.12mm = high quality, 0.28mm = fast
Initial Layer Height 0.20-0.30 mm 0.25 mm Thicker first layer helps adhesion
Line Width 0.4-0.5 mm 0.4 mm Match to nozzle diameter
Wall Count 2-4 3 More walls = stronger parts
Top Layers 4-6 5 Solid top surface
Bottom Layers 3-5 4 Solid bottom surface
Infill Density 10-20% 15% Higher for strength, lower to save material

Common Adjustments

If You Have Stringing

  • Reduce temperature by 5°C increments
  • Increase retraction distance by 0.5mm
  • Enable Z-hop (0.2-0.4mm)
  • Dry the filament thoroughly

If You Have Poor Bed Adhesion

  • Increase bed temperature to 65-70°C
  • Increase first layer nozzle temp to 210-215°C
  • Slow down first layer to 15-20 mm/s
  • Clean bed surface thoroughly
  • Apply glue stick or hairspray

If You Have Poor Surface Quality

  • Reduce outer wall speed to 30-40 mm/s
  • Ensure 100% part cooling
  • Check belt tension
  • Dry the filament

If You Have Under-Extrusion

  • Increase temperature by 5°C
  • Check for nozzle clogs
  • Calibrate e-steps
  • Check filament diameter

Brand-Specific Notes

Different PLA brands may require slight adjustments. Always check the manufacturer's recommendations printed on the spool.

Frequently Asked Questions

Start with 205°C nozzle and 60°C bed. Adjust nozzle temperature up if you see under-extrusion or down if you see stringing. Check your filament spool for manufacturer recommendations.

For direct drive: 0.8mm at 35mm/s. For bowden: 5mm at 45mm/s. These are starting points; adjust based on stringing results.

Standard speed is 60mm/s. You can print infill and inner walls up to 100mm/s. Keep outer walls at 40-50mm/s for quality. Modern printers with input shaping can go faster.
