Filament Swelling Filament swelling refers to the expansion of filament as it passes through the extruder and hot end. Some materials, like flexible filaments, are more prone to swelling, which can lead to extrusion issues and jams. Proper filament path design, cooling, and extruder tension adjustments can help minimize swelling. Using all-metal hot ends instead of PTFE-lined ones can also improve consistency. |
