I am sure thMyat this will happen in the not too distant future. Some of it is already happening. this is how the USA has stayed ahead of the pack.A small example: My 20-year old grandson, who is studying Electrical Engineering, came across anon-functioning Piano on his University campus. He took the covers off the piano and discovered that one of the wooden parts (don't know the name) on which the'hammer pivots and hits the wires that produce the sound, was broken.He removed the wooden part, created a replacement on a 3-D printer and in no time had the piano functioning. He is a pianist, so he was glad to be able toplay on that piano. This is a relatively simple example of 3-D printing. However, I don't think that Eric's depiction of the future is far fetched. Not only cars and planes, but body parts,clothes and shoes and other items of daily use will someday be manufactured by 3-D printers. Despite Trump's promise to bring back manufacturing jobs to the USA, I don't believe that the laid-off workeers in the USA will ever get back intomanufacturing. It is the whiz kids of today who will be the manufacturing workers of tomorrow. Not in my life-time, but surely in the lifetime of my children and grandchildren.
