I agree--the fact that 3D printing, in all its variety, is now on the radar of so many people and organizations bodes well, as does the spread of machines, and more and more materials, across the different market segments.
Seems like the dual forces of interest from the DoD and the commercial business sector could do a lot to advance the cause of 3D printing and additive manufacturing well beyond where it is today. Couple that with all the activity on the consumer front and you've got the real makings of a market.
Thanks, Beth. The DoD's desire to make 3D printing accessible and useful for soldiers is apparently one of the main forces behind the formation of NAMII, the additive manufacturing initiative/consortium we covered: http://www.designnews.com/author.asp?section_id=1392&doc_id=251513
Nice indepth account of how 3D printing is really changing the game when it comes to creating production parts from a wide variety of materials and in a much shorter time span. Beyond the implications in the aerospace applications you mentioned, Ann, the experimentation going on to use less expensive and more portable 3D printers in army applications, in the field, as a means of helping troops with extra parts they need or more significantly medical care is really exciting.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
