I'm reluctant to plug a commercial service, but have any of you looked at www.shapeways.com? It's an online 3D printing service where you can upload STL files and they mail you your part - in an amazing variety of available materials. I recently had a camera part made in stainless steel for a fraction of just the material cost to make it by machining from bar stock. There may be other similar things out there, but this is the one I've happened to come across.
eafpres, I had a similar experience after writing my first metals 3D printing article several months ago: it seemed like suddenly I saw media coverage of similar manufacturers everywhere. Of course, there are always way more service bureaus than manufacturers of the technology. Good to know the service bureaus are available.
78RPM, those snake and worm robots are fun, aren't they? The idea of their self-reconfiguration ability makes them even more interesting. And yes, things are moving awfully fast in these design areas. It often feels like the future is already here.
Nadine, to clarify again, I don't find my article more compelling, I find the concepts discussed in it of self-assembling and self-reconfiguring robots and methods more compelling than the lego-like so-called "digital materials" in the MIT paper. Anyway, too bad what you heard about isn't findable anywhere online. If you ever do find links, please let us know. It sounds a bit like MIT's so-called 4D printing, which is actually self-assembly combined with 3D printing. I wrote about that here: http://www.designnews.com/author.asp?section_id=1392&doc_id=260118
I want one of those Transformers. I've seen other Design News articles about robotic snakes and the like. It will be really useful when snake robots can crawl through small spaces, then reconfigure to lift a fallen piece of concrete rubble or take out a firehose or whatever the need is. The future is really being invented very fast, isn't it?
78RPM, the self-assembly and self-reconfiguring concepts in my other article are definitely more futuristic. OTOH, this Transformer-like robot is pretty here and now, if still small: http://www.designnews.com/document.asp?doc_id=256018
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.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
