Humans exploring Mars will probably get around in a Humvee-sized rover with a pressurized cabin like this one NASA is testing in the Arizona desert. It contains about 70 parts made with a Stratasys production-grade Fortus printer, including pod doors, camera mounts, vents, and housings.
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.
Oak Ridge National Laboratory has developed a surface preparation method to improve joining carbon composites with aluminum, with potentially far-reaching ramifications for high-volume industrial applications.
