Stringing/Oozing: The Unwanted Cobwebs

Stringing, also known as oozing, is like finding those annoying cobwebs in the corner of your room – they’re unsightly and you just want to get rid of them! Stringing occurs when small strings of filament are left behind on your print, marring its otherwise smooth surface.

Causes:

  • Retraction Settings: Retraction is the process of pulling the filament back into the nozzle to prevent it from oozing out when the nozzle is moving between printing areas. Incorrect retraction settings can lead to stringing.
  • Printing Temperature: If the printing temperature is too high, the filament will be more fluid and prone to oozing.

Solutions:

  • Calibrate Your Retraction Settings: Experiment with different retraction distances and speeds to find the optimal settings for your printer and material.
  • Lower the Printing Temperature: Try lowering the printing temperature by 5-10 degrees Celsius to see if it reduces stringing.

Under-Extrusion: The Case of the Missing Plastic

Under-extrusion is like trying to frost a cake with not enough frosting – it’s just not going to end well. It occurs when your printer isn’t extruding enough filament, resulting in gaps, weak layers, and a generally poor-quality print.

Causes:

  • Clogged Nozzle: A clogged nozzle is one of the most common causes of under-extrusion.
  • Filament Issues: Tangled filament, a jam in the extruder, or inconsistent filament diameter can all lead to under-extrusion.
  • Incorrect Extrusion Settings: Incorrect flow rate or extrusion multiplier settings can also cause under-extrusion.

Solutions:

  • Clean or Replace Your Nozzle: If you suspect a clogged nozzle, try cleaning it with a cleaning needle or replacing it with a new one.
  • Check Your Filament Path: Make sure your filament is feeding smoothly from the spool to the extruder.
  • Calibrate Your Extrusion Settings: Perform an extrusion test to calibrate your flow rate and extrusion multiplier settings.

Troubleshooting is Your Friend:
