Abstract: An example method for detection of impurities in additive manufacturing material includes illuminating, by a light source, a sample of additive manufacturing material with light, while illuminating the sample of the additive manufacturing material with light, causing a camera to acquire image data of the sample, and processing the image data to determine an amount of impurities in the sample of the additive manufacturing material. An example system for detection of impurities in additive manufacturing material includes a light source for illuminating a sample of additive manufacturing material with light, a camera for acquiring image data of the sample while illuminating the sample of the additive manufacturing material with light, and a computing device having one or more processors configured to execute instructions stored in memory for processing the image data to determine an amount of impurities in the sample of the additive manufacturing material.

Abstract: Methods of manufacturing a manufactured component, additive manufacturing systems that perform the methods, and storage media that directs additive manufacturing systems to perform the methods. The methods include supplying a feedstock material along a scan path. The methods also include delivering, to an addition location along the scan path, an amount of energy sufficient to form a melt pool of the feedstock material at the addition location. The methods further include moving the addition location along the scan path to move the melt pool along the scan path and define a consolidated material track from the feedstock material. The delivering the amount of energy includes selectively varying the amount of energy as a function of position along the scan path to increase a uniformity of the consolidated material track and/or to increase a uniformity of a consolidated material layer that is partially defined by the consolidated material track.

Abstract: Methods of additively manufacturing a manufactured component and systems that perform the methods. The methods include determining an energy application parameter at an addition location on a previously formed portion of the manufactured component. The energy application parameter includes an intersection area relationship that describes an area of intersection between the previously formed portion and a surface of a virtual geometric shape, which is positioned at the addition location, as a function of a size parameter of the virtual geometric shape. The methods also include supplying a feedstock material to the addition location. The methods further include delivering an amount of energy sufficient to form a melt pool of the feedstock material at the addition location. The amount of energy is based, at least in part, on the energy application parameter. The methods also include consolidating the melt pool with a previously formed portion of the manufactured component.

Abstract: Additive manufacturing system includes one or more processors configured to determine one or more geometrical characteristics of each of multiple segments of a build part at a candidate position of the build part relative to an additive manufacturing instrument. The geometrical characteristics include an angle of incidence between a beam line extending from a beam emitter and a surface normal of a respective skin of the corresponding segment proximate to the beam line. The one or more processors select, based on the determined geometrical characteristics, a first set of beam parameters for forming a first segment of the build part and a second set of beam parameters for forming a second segment of the build part. At least one of the beam parameters in the second set differs from the beam parameters in the first set.

Abstract: Methods of additively manufacturing a manufactured component and systems that perform the methods. The methods include determining an energy application parameter at an addition location on a previously formed portion of the manufactured component. The energy application parameter includes an overlap volume between a virtual geometric shape, which is positioned at the addition location, and the previously formed portion of the manufactured component. The methods also include supplying a feedstock material to the addition location. The methods further include delivering, from an energy source and to the addition location, an amount of energy sufficient to form a melt pool of the feedstock material at the addition location. The amount of energy is based, at least in part, on the energy application parameter. The methods also include consolidating the melt pool with a previously formed portion of the manufactured component to form an additional portion of the manufactured component.
