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
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
Fifteen European research centers have launched EuroCPS to help European companies develop innovative products for the Internet of Things.
Get your Allman Brothers albums ready. The iconic Volkswagen Microbus may be poised for a comeback, and this time it could be electric.
In 2003, the world contained just over 500 million Internet-connected devices. By 2010, this figure had risen to 12.5 billion connected objects, almost six devices per individual with access to the Internet. Now, as we move into 2015, the number of connected 'things' is expected to reach 25 billion, ultimately edging toward 50 billion by the end of the decade.
NASA engineer Brian Trease studied abroad in Japan as a high school student and used to fold fast-food wrappers into cranes using origami techniques he learned in library books. Inspired by this, he began to imagine that origami could be applied to building spacecraft components, particularly solar panels that could one day send solar power from space to be used on earth.
