Claim 0:
1. A method for calibrating a 3D printer, the method comprising 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;
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; and
determining a location of the center of the inner diameter of the tip orifice on the nozzle on the print head by utilizing the inductively sensed location and the provided information.
