What You May See
Fine, hair-like plastic cobwebs stretching between separate printing structures.
Likely Causes
- —Nozzle temperature is too high, leading to runny liquid phase polymer.
- —Retraction distance or speed is set too low for direct or bowden drive extruder.
- —Filament has absorbed atmospheric moisture.
What to Change
- 1.Reduce nozzle temperature by 5°C intervals within the recommended range.
- 2.Adjust retraction parameters (Direct: 0.8–1.5 mm / Bowden: 4.0–6.0 mm).
- 3.Dry the filament in a dedicated drying chamber before printing.
