Overview
On Demand Spare Manufacturing is the manufacturing of spare parts as-needed as opposed to a traditional stockpiling approach. It leverages digital manufacturing technologies such as additive manufacturing, 3D scanning, optimization algorithms, and supply chain logistics. On Demand Spare Manufacturing requires identifying the need for a spare, transporting materials for manufacturing, scanning, processing, mesh generating, manufacturing the spare part, finishing, inspecting, transporting the spare part to the system, and installing the replacement part.
