I fail to understand why geeks think 3D printing is the ultimate answer
to manufacturing when it is in fact slow and expensive.
There is one very successful additive manufacturing process: casting.
It is slow and expensive, *at the moment*, but it won't always be; and one of
the ways it will start to be rapid and cheap is by fabricating things which make
other things.
So, for example, it will make moulds, and the machinery to use them, which will
combine the advantages of bespoke design with the speed and low-cost of
traditional manufacturing.
Similarly, it will fabricate machines which wind, for example, copper wire onto
cast armatures.
