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
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
