The file contains a CNC 3DP Laser Nozzle intended for mounting on an engraving and cutting laser head from Opt Lasers. The emergent object can be used to direct the airflow from the engraving and cutting laser head’s fan into the working site of a 3D printer. This results in a laser processing speed increase, as well as prevents the formation of undesirable defects.
