The factory model ships identical parts around the planet. Distributed manufacturing inverts it: ship the design, make the part where it's needed, in the quantity it's needed, which is usually one.
For boat parts the logic is overwhelming. A discontinued hinge doesn't justify a production run anywhere, but it prints locally in an afternoon. The design travels at the speed of email; only the finished part travels by road.
This is the model 3D3D actually runs: designs generated parametrically, parts printed on demand, no inventory pretending to be a catalog. It's also why 'out of stock' doesn't exist here.
