Abstract
A method for calibrating a 3D printer includes the steps of providing information obtained in a factory calibration indicating a center of an inner diameter of a tip orifice in a metal extrusion nozzle and a center of a tip surface for the nozzle and inductively sensing the nozzle with an eddy current sensor when secured to a print head on a gantry or robotic arm of the 3D printer to identify a sensed location of the center of the tip surface of the nozzle. The method includes determining a location of the center of the inner diameter of the tip orifice on the nozzle on the print head and utilizing the provided information to locate the center of the inner diameter of the tip orifice.
