3D Printer FAQ

1. Nozzle Clogging During Printing
The main cause of nozzle clogging is poor adhesion of the first layer, which leads to the nozzle dragging and tangling the filament. This issue can be resolved by increasing the bed temperature (PLA: 65–70°C, PETG: 80–85°C) or applying a specialized glue to the print bed for improved adhesion.

2. Stringing Issues
Stringing often occurs due to excessive travel moves during printing. This can be mitigated by increasing the retraction speed settings in the slicer software.

3.“Fried Noodle” Effect (Material Buildup or Blobs)
This issue can be addressed by lowering the ambient temperature, drying the filament (using a filament dryer or other devices with drying functions), and thoroughly cleaning the print bed using appropriate cleaning agents.

4. Filament Breakage During Printing
This may be due to a brittle filament or lack of protection for the filament path. Using higher-quality filament and adding a PTFE (Teflon) tube to guide and protect the filament can help prevent breakage.

5. Filament Not Feeding / Dry Runs
This issue occurs when the filament fails to feed or gets stuck due to tangling in the spool. Always check the filament spool for tangles before starting a print.

6. Improving Print Surface Quality with PLA
When using PLA, implementing a variable speed strategy can significantly enhance surface quality. Set the outer wall print speed to 60mm/s (for higher precision), while keeping the inner wall speed at the default 40mm/s to maintain structural stability. This approach improves appearance without noticeably increasing print time.

7. Reducing Time on Parameter Calibration
By importing STL files into a pre-configured template provided by the supplier’s technical team, print parameters can be auto-calibrated, saving time on manual adjustments.
