However, under extrusion can also be caused by settings from the slicer software. One of the most common causes of under-extrusion is a clogged nozzle. In addition, you will notice small dots or holes on the surface of the object after the print is completed. When under-extrusion happens to your 3d printer, the 3d printed object will experience a lack of layers, lack of detail. Under-extrusion occurs when too little filament is extruded during a print. Thus, it’s important to keep filament dry to prevent nozzle blockage. When the filament is wet, the melting point of the filament will also be different between the wet part and the dry part. Note: Sometimes uneven extrusion can also occur due to wet filament. It also makes it harder to remove your 3d print from the printer bed because the amount of extruded material will be more than usual. This leads to a lot of reduced quality 3d printed products, even causing warping or breaking in parts. Due to a clogged nozzle, sometimes the nozzle extrudes too much in a short time. When the nozzle is dirty or clogged, the most obvious sign is that the nozzle extrudes unevenly. When there is a lot of dust on the cooling fan, it will affect the rotation speed and reduce the cooling capacity of the fan. If there is too much dust on the nozzle or other parts such as cooling fans, extruders, the quality of 3d printed products will be significantly reduced.

The reason is that the material is blocked in the nozzle, affecting the flow of the extruded material.ĭust around the extruder or motor parts is also a clear sign that you should clean the nozzle. You will see extruded material does not flow straight down. This is one of the common signs when your nozzle is clogged. Sign 2: Extruded material do not flow straight down The image below describes the differences between Missing first layer and Over extrusion in 3d printing. The consequence of missing the first layer is that your 3d print will lack detail or even warp. The reason is that when the filament is melted and flows to the nozzle, the flow is blocked due to an obstruction in the tube. Missing the first layer is one of the most common signs that your nozzle is dirty or clogged.
