Under-extrusion: my 3D printer is not extruding enough filament

Is there under extrusion?

What are the causes of under extrusion?

• Incorrect filament diameter

  A common mistake is that the wrong size filament is in the 3D printer. It is important that you pay attention to the diameter of the filament to be used. For many packages, the diameter is stated on the cover, but you can also measure it yourself. The settings of your 3D printer software show whether the filament format is recognised. The most commonly used diameter filament dimensions are 1.75mm and 2.85mm.

• Increase the extrusion multiplier

  Are you using the right filament size, but still having problems? Another solution is to increase the extrusion flow rate so that the 3D printer uses more filament. Try this in increments of 2.5% at a time until you find the right percentage. However, make sure to stay below a total of 115% or other problems will arise.

• Increase the print temperature

  A print temperature that is too low can cause the filament to not melt properly. The 3D printer will compensate for this by printing the material with a higher pressure. Under extrusion can occur due to the temperature and pressure that is too low. Try to achieve the correct temperature by repeatedly increasing the temperature by 5 degrees until the correct temperature is reached.

Other problems that can lead to under extrusion are an incorrectly rolled filament spool, a blockage in the print head (nozzle), the print speed or an interrupted path from the spool to the extruder. If the print head or nozzle is clogged, you can try to clean it. If this does not work, you can easily order a new print head from 123-3D.
