Abstract: 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.

Abstract: Some embodiments may include an optical assembly usable to process light output from a laser source. The apparatus may include a housing to receive a distal end of an optical fiber that outputs the laser light; one or more actively cooled or passively cooled beam traps contained within the housing or coupled to the housing; and one or more optical apertures located inside the housing, at least one of the optical apertures to define a numerical aperture (NA) of a first portion of the laser light based on a radial dimension of the at least one optical aperture, the at least one optical aperture arranged to pass the first portion of the light and redirect a second different portion of the laser light to the one or more actively cooled or passively cooled beam traps. Other embodiments may be disclosed and/or claimed.

Abstract: A method of making a three-dimensional object. The method comprises: a) positioning a layer of particles over a build plate; b) exposing the layer of particles to a first laser beam having a first set of beam characteristics, thereby heating the layer sufficiently to fuse at least a portion of the particles together to form a build layer; c) exposing a first region of one of i) the layer of particles or ii) the build layer to a second laser beam having a second set of beam characteristics to provide a first temperature profile for the first region; and d) exposing a second region of one of i) the layer of particles or ii) the build layer to a third laser beam having a third set of beam characteristics to provide a second temperature profile for the second region, the second temperature profile being different than the first temperature profile, wherein both the first region and the second region are in the layer of particles or both the first region and the second region are in the build layer.
