Original Abstract Submitted
a 3d printer includes a print bed adapted to receive a layer of print medium, a recoater adapted to distribute the print medium onto the print bed, a laser source adapted to generate a non-interactive laser beam and an interactive laser beam, a controller connected to the laser source to direct the interactive laser beam to the at least one predetermined location, a plurality of fiducial features associated with the recoater, wherein the plurality of fiducial features are presented by the recoater while the recoater distributes the print medium on the print bed to form a layer, and a scanner connected to the controller to detect, via the non-interactive laser beam, the plurality of fiducial features and provide location information for locations of individual ones of the plurality of fiducial features. the controller performs a calibration to adjust where the interactive laser beam is directed to the print medium.
