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: A device may deposit a first print material having first material characteristics corresponding to a material strength in a space over a build plate. A device may selectively deposit a second print material having second material characteristics at a print location to modify the material strength at the print location, wherein the print location is at an interface between a first component and a second component.

Abstract: Apparatus and system for optimizing package of scanner heads is disclosed. An apparatus in accordance with an aspect of the present disclosure comprises a monolithic multi-optics scanner head housing configured to receive multiple sets of galvanometer mirror scanners (galvo) and a beam entry window. Each set of galvos receives a laser and redirects the laser using a mirror.
