After customer complaints about the Dual Extruder v3, LulzBot engineers began a thorough design review to address frequent jamming and other issues by using several technologies at their disposal, including FLIR and airflow analysis. In the analysis, it was discovered that the fan was inadequately transferring heat from the heat sink, causing the filament to soften prematurely in the feed path resulting in jamming and inconsistent filament feeding.
The redesigned fan mount that resulted from the analysis enables the Dual V3.1 to cool the unibody heatsink more efficiently, reducing heat creep and jamming.
