NASA's Rocket Maker To Begin 3D Printing Flight-Ready Components 40

Lucas123 writes: United Launch Alliance (ULA), the company that makes rockets for NASA and the U.S. Air Force, plans to 3D print more than 100 flight-ready components for its next-gen Vulcan rocket. The company also just printed its first flight-ready component, a new Environmental Control System for its current Atlas V rocket. The ECS assembly had previously contained 140 parts that were made by third party suppliers, but ULA was able to reduce the parts to just 16, resulting in a 57% part-cost reduction. Along with cost reduction, ULA said 3D printing frees it from contracts with parts providers who may or may not deliver on time depending on whether the deem the rocket maker a priority at any given time. The company, which launches 12 rockets each year, is also hoping to use 3D printing for a more traditional role — rapid prototyping of parts. "We have a long list of [parts] candidates to evaluate — over 100 polymer parts we're considering and another 50 or so metal parts we're considering," said Greg Arend, program manager for additive manufacturing at ULA.

>I'm inclined to call that step very, very non-obvious.

Agreed - it's not very obvious, and kind of awkward. The first time I wanted to do this, it took a little bit of head-scratching and thinking "what if I click this button?" before I figured it out - perhaps 30 extra seconds of reflection on my part.

Thankfully, iOS is evolving rather quickly, and if this was judged a useful feature, in a future release an "email PDF" button may be added to the "Add Bookmark/Add to Reading List/Add to Home Screen/Mail Link to this Page/Tweet/Print" options that are already available directly in mobile Safari...

>I *DEFY* you to send a pdf from safari via e-mail.

In Safari with the PDF visible, tap on it once to make the "Open in iBooks" option appear, then tap on the "Open in iBooks" button in the upper right hand corner of the document. Once the iBooks app opens automatically, click on the "Email/Print" button (third button to the right at the top, with the little arrow coming out of a square), then click on the "Email" option in the pop-up menu. From there, the mail app will come up with the PDF in attachment/visible in the body of the mail. Type in the email address that you want to send to, then tap on "Send".

4 taps, an email address to type in, and then one more tap to send, all done in a few seconds. How hard is that?

The summary description on ./ is wrong. If one does RFA all the way to the end, one will see the following:

Editors Note - This story originally contained a representation that the biometrics trial in Atlanta and Detroit included the fingerprint scanning of US citizens. This has since been proved to be incorrect and the story has been modified - only non-US citizens will be expected to provide a biometric record.

As a US citizen living in France, and often travelling through Detroit and Atlanta to get to/from Chicago, I'm relieved that I won't be delayed by this hassle. As a human being, I don't agree with the idea of requiring visiters to submit their fingerprints to the the US government - I feel it is infringing on one's human rights and/or privacy, and feel ashamed when I see fellow travellers submitting to this procedure upon entry into the US - but it's too early in the morning for me to formulate a clear and logical argument against the requirement...
