BCN3D Sigma Extruder
thingiverse
Designed specifically for the BCN3D Sigma printer, with compatibility not guaranteed for the Sigmax model. The original design contained a critical flaw: the airflow from the hotend's cooling fan inadvertently cooled the heatblock, hindering performance. This revised design rectifies this issue. Furthermore, it incorporates a 24v radial fan for part cooling and a strategically positioned fan shroud to direct airflow directly at the print. This setup should minimize the cooling effect on the nozzle, optimizing overall performance.
