Thanks for your enthusiasm, Deberah. I enjoy bringing "amazing but true" materials and assembly stories to our readers.

You're right, jhankwitz, it's specific parts on the SpaceX Dragon V2 that were 3D printed. OTOH, these are engine combustion chambers for the thrusters

which says a lot about the mechanical properties possible with direct metal laser sintering.

RandD, thanks for the reminder about the process of engineering regarding new materials and assembly/construction methods. I suppose it could be summed up as "don't trust and always verify" which can only be done during the actual design process. I think of it a bit like the process called "discovery" in legal situations.

No doubt this 3d printed steel should be compared with original steel and yes if the compositions and the strenght of both are same then definitely 3d printed steel is on its way towards future technology .

Ann thanks alot for such an interesting post , thats really very  great and amazing to see where the technology is moving and going 3 d printing is no doubt becomming very popular and it will be one of the famous technology in future.

eafpres: You raise several good points, but none are new. All would have to be considered for any new material, or construction technique. I'm sure all these same points were considered when riveted aluminum was being touted for airplane fuselages. Sometimes, it's not all knowable from day one, but that doesn't mean it shouldn't be tried. It does mean adequate prudence is called for, good testing, and continuous evaluation. This is what we (Engineers) do.

ChasChas, I think you're ahead of the game there--great idea. This could be combined with those climbing robots that do maintenance on wind towers we wrote about

Hey Cadman, glad you liked this one. And yes, I sure do get that joke--glad to hear it.

Regarding comparable properties of 3D-printed metals, some such studies have already been done. Some are mentioned in this article we posted by Optomec:  
http://www.designnews.com/document.asp?doc_id=271188
Independent tests that actually showed better yield and tensile strength in 3D printed Ti-6Al-4V alloys used for structural components on aircraft made with Optomec's machines are discussed here
http://www.designnews.com/author.asp?section_id=1392&doc_id=264842
Also, for comparison, specs for EOS' various steels and other metals, which conform to specific ASTM standards for mechanical properties and chemical composition, can be accessed here

78RPM, there aren't any existing standards for 3D printing methods, although that's the subject of several America Makes (formerly NAMII) projects, as we've reported. We've also reported on ASTM standards efforts for 3D printed parts. There certainly are existing industry standards for steel parts in the construction industry. And that's certainly true in other industries using 3D printed metal parts for end-use apps, such as aerospace, sporting equipment, and medical and dental implants.

Latest Analysis
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
Researchers have developed a new flexible fabric that integrates both movement and sensors, introducing new potential for technology-embedded clothing and soft robots.
Made by Monkeys highlights products that somehow slipped by the QC cops.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
