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
Many of the new adhesives we're featuring in this slideshow are for use in automotive and other transportation applications. The rest of these new products are for a wide variety of applications including aviation, aerospace, electrical motors, electronics, industrial, and semiconductors.
A Columbia University team working on molecular-scale nano-robots with moving parts has run into wear-and-tear issues. They've become the first team to observe in detail and quantify this process, and are devising coping strategies by observing how living cells prevent aging.
Many of the new materials on display at MD&M West were developed to be strong, tough replacements for metal parts in different kinds of medical equipment: IV poles, connectors for medical devices, medical device trays, and torque-applying instruments for orthopedic surgery. Others are made for close contact with patients.
New sensor technology integrates sensors, traces, and electronics into a smart fabric for wearables that measures more dimensions -- force, location, size, twist, bend, stretch, and motion -- and displays data in 3D maps.
