NASA, Industry Test "3D Printed" Rocket Engine Injector

NASA, Industry Test "3D Printed" Rocket Engine Injector | History 2[+or less 3].0 | Scoop.it

NASA and Aerojet Rocketdyne recently finished testing a rocket engine injector made through additive manufacturing, or 3-D printing.
The series of tests demonstrated the ability to design, manufacture and test a critical rocket engine component using selective laser melting manufacturing technology -- a method that employs high-powered laser beams to melt and fuse fine metallic powders into three dimensional structures.
This type of injector manufactured with traditional processes would take more than a year to make, but with these new processes it can be produced in less than four months, with a 70 percent reduction in cost.

If 3d printing is good enough for NASA shouldn't we all be thinking about it...

This is a pretty informative interactive map of the largest ports in the world. Very well put together to help some understandings of trade. Most of the ports are on the East coast of China which is the Pacific Sea. The reason there are probably so many here in China is because they make a large amount of product that needs to be shipped worldwide. They are like the leading country in imports and exports to other global or major global markets.

This more clearly shows the regional restructuring of the global economy than just about anything I've ever seen, especially manufacturing.  The 8 largest and busiest ports in the world are all in East or Southeast Asia (and 11 of the top 13).  A quick glance at the historical charts will show that most of these were relatively minor ports that have exploded in the last 20 years.
