​On site fixtures and hardware

Using stock metal, filament and a small CNC shop+3D print farm, it would be possible to make things like doorknobs, molding, coat hangers, etc. on site in the final stages of construction for larger buildings like corporate offices. You could design to theme for the customer. It might even be possible to make some things like plumbing fixtures. The upside is it would be cheaper to fabricate on site and on demand because there’s less middlemen, inventory management, shipping, waste, etc. The print farm and CNC shop would also have a predictable and reliable utilization contract. Fabrication is slow, but could be practical for some things. But with many printers, it could work for JIT. 20 3D printers would fit in a small truck. Not too expensive to set up, transport and run with an EV. For the odd CNC job, some prosumer mills like a couple of Nestwork C500s would work. The trick to this is identifying which products like doorknobs, shelving parts or small bins can be economically printed/milled at high enough quality and within time for use. Lots of places have print studios in house, so this would be similar. Maintenance could keep one or two 3D printers or mills on hand for things that break and the design files could be stored alongside blueprints.
