Segmenting your spare parts supply chain for 3D printing

Understanding how to identify where to use 3D printing in a supply chain is one of the first key questions to address.


From warehouse robots (very real) to equipment that you control with your mind (in the labs), new technologies appear so regularly that it can be hard to separate real from science fiction. But in the spare parts business, 3D printing has become “here and now”.
