What\u2019s the issue?<\/p>\n\n\n\n
Under-extrusion is that the printer is not supplying sufficient filament for the print. It may cause some defects like thin layers, unwanted gaps, or missing layers.<\/p>\n\n\n\n
Possible causes<\/p>\n\n\n\n
—Nozzle Jammed<\/p>\n\n\n\n
—Nozzle Diameter Not Match<\/p>\n\n\n\n
—Filament Diameter Not Match<\/p>\n\n\n\n
—Incorrect Extrusion Setting<\/p>\n\n\n\n
Troubleshooting tips<\/p>\n\n\n\n
—Nozzle Jammed<\/p>\n\n\n\n
If the nozzle is partly jammed, the filament will not be able to extrude well and cause under-extrusion.<\/p>\n\n\n\n
Go to\u00a0the nozzle jammed\u00a0section for more details on troubleshooting.<\/p>\n\n\n\n
—Nozzle Diameter Not Match<\/p>\n\n\n\n
If the nozzle diameter is set to 0.4mm as commonly used, but the nozzle of the printer has been changed to\u00a0a larger diameter, then\u00a0it can cause under-extrusion.<\/p>\n\n\n\n
Check the nozzle diameter<\/p>\n\n\n\n
Check the nozzle diameter setting in the slicing software and the nozzle diameter on the printer, and make sure that they are the same.<\/p>\n\n\n\n
—Filament Diameter Not Match<\/p>\n\n\n\n
If the diameter of the filament is smaller than the setting in the slicing software, it will also cause under-extrusion.<\/p>\n\n\n\n
Check the filament diameter<\/p>\n\n\n\n
Check if the setting of filament diameter in the slicing software is the same as the one you are using. You can find the diameter from the package or the specification of the filament.<\/p>\n\n\n\n
Measure the filament<\/p>\n\n\n\n
The diameter of a filament is commonly 1.75mm, but the diameter of some cheap filaments\u00a0may be\u00a0less. Use\u00a0a caliper to measure the diameters of the filament at\u00a0several\u00a0points\u00a0in a distance, and use the average of the results as the diameter value\u00a0in\u00a0the slicing software. It is recommended to use\u00a0high-precision filaments with standard diameters.<\/p>\n\n\n\n
