Fixing 3D Printing Problem: Not Extruded

Not extruding is a common challenge faced by many new 3D printer owners, but the great news is that it can usually be resolved with a few simple adjustments! If you find that your extruder is failing to push filament at the start of your print, there are four main culprits to consider.

Below, we'll explore each potential issue and outline the necessary settings to help you get back on track.

⚙️What is Not Extruding?

Not extruding refers to the situation where your 3D printer’s nozzle fails to push out filament while printing. This often results in gaps, missing layers, or incomplete prints.

❓Common Causes

Clogged Nozzle

A build-up of filament residue or debris can block the nozzle, preventing the flow of material.

Filament Jam

Improper feeding of filament due to tangling, knots, or an incorrect path can stop extrusion.

Incorrect Temperature Settings

If the hot end temperature is too low, the filament may not melt properly, leading to extrusion failure.

Bad Filament

Moisture or degradation of filament can affect its flow characteristics, causing it to jam.

🛠️Solutions

A clogged nozzle is a common reason for filament not extruding. You can tell this is happening if the extruder motor is clicking or slipping but the filament is not being pushed out. Clogged nozzles can be caused by too much retraction or debris inside the nozzle. Refer to the [Nozzle Clogging] article for detailed solutions. 

Adjust Nozzle Temperature

Incorrect temperature settings can also prevent extrusion. Ensuring the nozzle temperature is correctly set according to the recommended printing conditions for the specific filament is crucial. Please ensure the nozzle temperature is set according to the filament's recommended settings, which can be found on the package or in Technical Data Sheet (TDS).  

Most 3D printers use a small gear to push the filament back and forth. If there are plastic shavings or if the extruder motor is spinning but the filament is not being pulled into the extruder, then the filament might be stripped. Refer to the [Grinding Filament] article for detailed solutions.

If the nozzle is too close to the build table surface, there will not be enough room for plastic to come out of the extruder. This can be identified if the print begins to extrude normally after the first several layers. Therefore, try increase the Z offset in the slicer until there is enough room for the plastic to extrude properly.

Experimentation and patience are key to mastering the art of 3D printing. If you continue to encounter difficulties, please contact Overture Service for further assistance.
