If the theory behind this article was true then tube socks would be made in your local store as opposed to some factory in China. If the socks business can't leave the factory, why do people think 3D printed good will leave? All this progress will lead to is Chinese factories having smaller workforces. I visited a sock factory with a work force of a few thousand people producing few million socks per day. When you get to such scales your biggest cost is management oversight, which is why manufacturing is going to stay in large factories.
