Machine spare part obsolescence is a major headache for manufacturers. The stockout costs or consequences of non-available spare parts are invariably higher with longer periods of downtime. As time equals money, in the majority of manufacturing operations maintenance staff take their own approaches to stock management. One such way is the squirrel approach where obsolete parts are gathered for insurance purposes. Some manufacturers look to rationalize their spare part stock profile and often target high-value slow-moving parts, which are usually also the obsolete parts.
Unfortunately the rapid developments in industrial automation have accelerated the obsolescence process, leading many companies to be caught short. But with the recent burst of 3D printers becoming more accessible to the masses, we have been asking ourselves if the dawn of the 3D printer will eventually make obsolescence obsolete. The advancement in 3D printing could well change the process in which spare parts are managed – if the International Space Station can use a 3D printer to print spare parts, why can’t any other manufacturer in the future?
