Liquid rocket engine hardware components can take many months, and in some cases over a year, to procure and fabricate. One NASA project, called Long Life Additive Manufacturing Assembly (LLAMA), is testing 3D printing methods for building liquid rocket engine components that would save a considerable amount of time and money compared to traditional manufacturing methods. The advanced manufacturing methods employed by LLAMA can cut the time required for rocket engine nozzle production by more than half compared to traditional processes. It also significantly reduces the part count since less pieces need to be manufactured individually and then assembled. Credits: NASA
