The H2D printer uses advanced sensing technology to automatically and intelligently optimize extrusion for each filament. It does this by combining data from a servo motor on the extruder, which can detect the force used to push the filament, and high-resolution eddy current sensors on the nozzle that measure internal nozzle pressure in real time.
This allows the printer to accurately determine how the filament flows and automatically calibrate Pressure Advance settings to match the specific characteristics of the material being used. As a result, prints come out with improved surface smoothness and sharper edge definition.
This calibration process happens smartly at the beginning of a print, but only when needed. If the same filament has already been used in a previous print, and the printer has stored its calibration data, it will skip recalibration to save time. This ensures consistent high-quality results without the need for manual flow rate tuning, while avoiding unnecessary repeat calibrations.
