What I found more compelling was the concept of self-assembly and self-reconfiguration, rather than the lego-like MIT digital materials in the link I gave before: http://cba.mit.edu/docs/papers/06.09.digital_materials.pdf Was this the MIT digital materials you referred to? If not, can you tell us what you were referring to?
NadineJ -- I think the "more compelling" concept is a matter of timeline. The MIT papers do like digital assembly similar to Lego blocks. An article in Wired in recent months discussed a method being used to construct skyscrapers in China in two weeks using a modular approach.
We have seen the open software approach be applied to hardware in the Arduino and BeagleBone and the modular shields we stack upon them. Xerox PARC has done work on 3D printing of circuit boards. These concepts are making traction in the marketplace already.
Ann's earlier article http://www.designnews.com/author.asp?section_id=1392&doc_id=261138 seems to be more futuristic where objects act like (maybe become?) living organisms and adapt their shape and purpose to the environmental need at hand. Science fiction such as the Transformers movies always inspires invention of the future.
Nadine, I googled "MIT digital materials" and came up with several links that seem to be talking about LEGO-like "printing", although it looks more like assembly to me. At the micron level described in a 2009 paper http://cba.mit.edu/docs/papers/06.09.digital_materials.pdf one might be able to call this "digital assembly," but at larger scales that terms seems misleading. Is this what you were referring to?
In any case, it seems to be related to self-assembled and self-reconfigurable devices and materials, on several scales, which DN covered here: http://www.designnews.com/author.asp?section_id=1392&doc_id=261138 and which I find much more compelling.
It's important to remember that the technology for SLS with metals and with plastic is not the same, so it's not a matter of a 3D printer company using one line of printers for either materials set. It's also a really different expertise set. So far, plastic-based companies like Stratasys are partnering with metals-based companies like Optomec, and 3D Systems has bought the expertise.
A make-your-own Star Wars Sith Lightsaber hilt is heftier and better-looking than most others out there, according to its maker, Sean Charlesworth. You can 3D print it from free source files, and there's even a hardware kit available -- not free -- so you can build one just in time for Halloween.
Some next-generation bio-based materials are superior in performance to their petro-based counterparts, but also face some commercial challenges. This is especially true of certain biopolymers, adhesives, coatings, and advanced materials.
Cars and other vehicles, as well as electronics and medical devices, continue to lead the use cases for the new plastics products we've been seeing, as engineers design products for tougher environments.
LeMond Composites, founded by three-time Tour de France cycling champion Greg LeMond, is the first to license a new carbon fiber production method invented by Oak Ridge National Laboratory (ORNL) that's faster, cheaper, and greener.
This month will mark the launch of the SpeedFoiler, a super-fast, ultra-lightweight foiling catamaran that can fly short distances over water faster than other foiling designs, in part because of its carbon composite materials.
