Maybe not so much on a large scale, but have you googled "additive manufacturing" lately? We're there my friend.
Sent care of the guys that made Star Trek low tech.
Yeah, I know. I'm in contact with some of the guys working on printing spare parts for trucks etc. and we're not in Kansas anymore. Used to be that you needed a machine shop to do stuff. I worked in the Middle East for many years, and it was amazing to do contract work (IT) for the oil companies. ARAMCO and ARCO had shops where you could lathe/cast/whatever tools in a matter of days.
Now? It's just a question of size and materials. That will come. We're there, the world just hasn't woken up to it. Post industrial... HAH, we ain't seen nothing yet.
And it's not going to be fun for the 'first world'/'developed world' -- whatever moniker floats your boat -- just look at telecoms. We've invested in infrastructure over the years, yet it's in Kenya you have a real functioning micropayments system called m-pesa. Their infrastructure investment is zero, comparatively.
With AM, it no longer comes down to transporting raw materials somewhere to 'refine' it (adding value through the manufacturing process). Now we're going to end up with manufacturing 'in situ', and the only thing that's transported is going to be the raw materials used to manufacture the widgets. I'm in the logistics industry, and we're going to be hit hard.
I'm all for this, and I love the idea of being able to 'make' whatever I need, customised to fit my exact needs on the spot, but I'm worried that we're woefully unprepared for the chaos that will ensue. Mind you, that's the nature of paradigm shifts...
