Extrusion Clogging Extrusion clogging occurs when the filament becomes blocked in the extruder, preventing proper material flow. Common causes include debris, degraded filament, improper temperature settings, or using incompatible materials. A clogged nozzle leads to under-extrusion or print failure. Cleaning the nozzle, ensuring proper storage of filaments to avoid moisture absorption, and regularly maintaining the hot end can prevent clogging. Advanced printers may include clog detection systems that pause the print if a blockage is detected, allowing users to clear the clog and resume printing without wasting material. |
