Complexity of a geometry of a desired (i.e., target) three-dimensional (3D) object being produced by an additive manufacturing system, as well as atypical behavior of the processes employed by such a system, pose challenges for producing a final version of the desired 3D object with fidelity relative to the desired object. An example embodiment enables such challenges to be overcome as a function of feedback to enable the final version to be produced with fidelity. The feedback may be at least one value that is associated with at least one characteristic of a printed object following processing of the printed object. Such feedback may be obtained as part of a calibration process of the 3D printing system or as part of an operational process of the 3D printing system.

A system for separating objects within a stacked powder print bed of nested objects comprises a build box configured to contain the powder print bed. The build box has a build box top and a build box floor. The system further includes an elongated aperture formed in a side wall of the build box, and a de-powdering subsystem configured to mechanically and electrically engage the build box. A separating blade associated with the de-powdering subsystem is configured to be inserted through the elongated aperture and into the powder print bed between a top-most print bed layer of the nested objects and a second print bed layer directly below and contiguous with the top-most layer, thereby forming an isolated powder print bed between the separating blade and the build box top. The unbound powder may be agitated by various techniques and subsequently removed from the objects.

Printable high-strength alloys, including aluminum alloys can be produced in an additive manufacturing process. Such alloys can include aluminum-silver (AlAg) alloys that are produced by a laser melting process using a powder bed fusion. The results of the process and the characteristics of the produced alloy can be determined by controlling at least an energy beam power, an energy beam speed, and/or an energy beam size. The operational parameters can be controlled with high precision to produce a printable, high-strength aluminum alloy.

An additively manufactured alloy component has a first portion formed of the alloy and having a first grain size, and a second portion formed of the alloy and having a second grain size smaller than the first grain size. In an embodiment, the alloy component is an alloy turbine disk, the first portion is a rim region of the alloy turbine disk, and the second portion is a hub region of the alloy turbine disk. The first and second grain sizes may be achieved by controllably varying the laser power and/or scan speed during additive manufacturing.
