The prototype Atlas printer, announced on Wednesday, can print objects up to one meter long using titanium, aluminum, and other metals instead of the plastics, resins, and filaments that many commercial and consumer 3D printers use. That means it could print an entire engine block for a car or truck, for example, replacing the specialized machines and tooling that are currently required to make those types of products in a factory.
GE said it plans to unveil the Atlas in November. The prototype can only print objects up to one meter in two directions, such as length and width, but once the production version is ready next year, it will be able to print objects up to one meter in any direction.
Seems like just the thing for cheap rocket engines.

Today is the anniversary of the first spaceflight of SpaceShipOne. At the time, everyone expected its successor to be flying passengers before the decade was out. As we now know, that was over-optimistic, for a variety of reasons. But here are my blog posts from the event at the time.
There was an interesting conference in New York last week (that I would have liked to attend if it had been in my budget). It’s still hard to raise money for it, because modern philanthropists don’t know the history, and can’t conceive of anyone but NASA doing such things, but I think that this is the future.
