The Induction Heating Assembly – Right is the central functional module that enables contactless, rapid heating of the hotend. It features an integrated induction coil which, through electromagnetic induction, generates eddy currents inside the hotend assembly, thereby allowing for a rapid rise in temperature. In addition, the module includes an interface for temperature sensing and a Hall sensor to transmit temperature data and detect the installation status of the hotend.
