Aerospace components have long been fabricated using traditional manufacturing methods such as forging. That method requires significant post processing. 3D printing offers new alternatives. Laser-based additive manufacturing provides an alternative, single-step method for producing complex, multi-material, dense or porous, near net-shape parts that often outperform their traditionally manufactured equivalents, offering enhanced properties. Formalloy is using laser metal deposition to 3D print aerospace components for rocket nozzles and heat exchange. (Source: Form Alloy) 3D printing company, Formalloy, is producing parts using a laser-based process because of its ability to create new advantageous shapes. “Our technology is known as LMD. That’s a method where you blow power and heat it with a laser. You build the part layer by layer,” Melanie Lang, managing director at Formalloy, told Design News . “The first advantage of this process is the ability to achieve design features such as internal cooling chambers or multi-material components […]
