GE Aviation's Additive Development Center near Cincinnati has produced a number of firsts but they are now demonstrating a working 3D-printed jet engine for an RC-sized model. The engine turns at 550 rotations per second and is made entirely from metal 3D-printed parts. They used the same EOS M270 3D printer that they use to produce the first and only FAA flight-approved 3D-printed hardware, a T25 pressure and temperature sensor for use in GE90 jumbo jet engines.

U.S. technology and engineering conglomerate GE said on Saturday it had signed $15 billion of business deals with Saudi Arabia as part of the kingdom's drive to diversify its economy beyond oil.
It came as dozens of senior U.S. business executives met Saudi counterparts at a conference coinciding with the visit of President Donald Trump to Riyadh.
[...] Among the projects, GE will help make Saudi power generation more efficient and provide digital technology to the operations of oil firm Saudi Aramco, aiming to create $4 billion of annual productivity improvements at Aramco. It will cooperate in medical research and training.

As an amateur telescope maker, I know how to use a lathe and milling machine. I've always been puzzled as to what the advantage of 3-D printing is.
Just this morning I remembered that shortly after Tsutomu Shimomura started working at Los Alamos National Laboratory, he submitted a drawing to the machine shop, the specified a seamless, hollow metal sphere.

People have been casting hollow metal shapes for thousands of years, but when all you have is a 3-D printer, all your projects look like 3-D printing projects! History never happened. Reinvent everything.

yeah I know how to cast a hollow sphere but can you do it with a close tolerance?

Nope, simply not possible using any human technology. Contact the aliens who built Stonehenge and ask if they want to do some contract work.
