Over-extrusion happens when your printer extrudes too much material, causing blobs, zits, and dimensional inaccuracy. While less catastrophic than under-extrusion, it creates poor surface quality and prevents precision parts from fitting correctly.
Symptoms:
-
Bulging corners.
-
Rough, inconsistent surfaces.
-
Dimensional inaccuracies.
Causes:
-
Extrusion multiplier too high.
-
Incorrect filament diameter setting.
-
Overheating material flow.
Troubleshooting Steps:
-
Lower extrusion multiplier (flow rate).
-
Verify filament diameter in slicer.
-
Check for slicer bugs or multiple extrusion commands.
Prevention Tips:
-
Run calibration cubes to tune flow.
-
Use consistent filament suppliers for diameter accuracy.
