By using selective laser sintering (SLS) powder bed additive manufacturing technology, ZeroAvia is able to conduct high-speed design, manufacturing, and testing cycles, and quickly combine typical components or their functions into new integral structures. The key components in SuperStack Flex auxiliary equipment - anode, cathode, and coolant manifolds, thermal management, humidification, and air compression systems - have been reduced from over 200 to less than 100, with a weight and volume reduction of approximately 50%. The reduction in the number of components means that the system is lighter, more compact, more reliable, and has lower costs.
