Abstract: Systems and methods for multi modular ring mode fiber optic configuration, laser powder bed fusion, and fine process control during an additive manufacturing (AM) process. A multi-mode ring laser beam with a first power distributed in a first beam is generated, as a spot beam or a first ring beam, and a second power distributed in a second ring beam surrounding the first beam. The multi-mode ring laser beam is applied to one or more materials to transform the material(s) into an AM build piece. An AM method includes depositing a powder first material in a powder bed, exposing the powder first material to a second material, wherein an absorption coefficient of the second material is higher than an absorption coefficient of the first material at the wavelength, and applying a laser beam with a wavelength to the powder first material and the second material to generate a composite material. An AM method includes controlling an optical component to apply a laser beam to a region of material during an AM process, receiving sensor data regarding the region; determining a process characteristic of the region based on the sensor data, obtaining a comparison by comparing the process characteristic to a target characteristic, and modifying a variable corresponding to control of the optical component based on the comparison that modifies a printing output in accordance with a target output.

Abstract: An apparatus for producing spherical metallic powders through continuous ball milling. The apparatus includes a comminution component. The comminution component includes an inlet to receive a metallic material at a first region within the comminution component and an outlet to dispense the metallic powder from a second region within the comminution component. The apparatus includes a plurality of grinding components to grind the metallic material, the plurality of grinding components being arranged within the comminution component. The apparatus includes a drive component, connected with the comminution component, to induce movement of the metallic material and the plurality of grinding components within the comminution component such that the metallic material is fragmented through contact with the plurality of grinding components at the first region and an external surface of the fragmented metallic material is altered at the second region to produce the metallic powder.

Abstract: A printer and methods for additive manufacturing a build piece may include a camera and an optical spectrometer obtaining spectral information and optical information from a region of melted material to determine a defect condition based on an evaluation of processed spectral or optical information. A processor or a computer may process the obtained and optical information and determine a defect condition during the additively manufacturing process. The obtained spectral and optical information may be of the region of the melted material, a melt pool and a mushy zone. The printer and method may include a controller configured to modify a process parameter to shape the weld pool to obtain a desired effective absorptivity of a portion of the weld pool, e.g., to increase the effective absorptivity relative to an absorptivity of a surface of the powder or material deposited by the depositor and to maintain an acceptable temperature of the weld pool during the additively manufacturing process.
