Application: Laser array for laser powder bed fusion processing of metal alloys (Patent ID: US20240207934A1)
The patent filed by The Boeing Co. describes systems and methods for additively manufacturing objects using an array of heat sources to generate multiple melt pools in a powder bed. By controlling the distance and heat from each heat source, a combined melt pool is created that is larger in size and encompasses the individual melt pools, allowing for the solidification of the object. The system includes an array of lasers that can be moved relative to the powder bed, with each laser having a mechanically adjustable position to control the heat spots generated. Additionally, the system can adjust the heat spot pattern, diameter, and pitch to control the size of the combined melt pool.
The patent also includes claims related to the configuration of the heat sources, the use of optical components to direct radiation, a powder delivery system, and the exposure of base alloys to multiple beams of focused energy. The computer-executable instructions stored on a computer storage device outline the operations for applying heat to metallic particles using multiple heat sources to generate melt pools, control the distance and heat from each source, and allow for the solidification of the combined melt pool to form an object. Overall, the patent focuses on the innovative use of multiple heat sources in an array to improve the additive manufacturing process and create larger, more complex objects efficiently.
