eafpres, thanks for the feedback. My April feature on self-assembly and self-reconfiguring robots will touch on several of these subjects. If you're interested in nanoscale self-assembly, I suggest you check out DNA origami and the Wyss Institute work on DNA 2D tiles and 3D bricks.
Thanks for sharing this. I watched the underwater cube, then I watched Skylar's TED talk as well. When you think about a system like this, it makes sense that 3D printing (or some form of 3D manufacturing) and self-assembly go together--things we want in the world are mainly 3D, so they are assembled out of 3D parts (the printer that prints out of stacked sheets notwithstanding--they are still 3D--they have thickness!).
It is interesting to think about gravity as the main source of energy (potential energy) and building structures. In a sense, this is already done on a large scale or certain types of retaining walls. You have 3D blocks that fit together, and gravity provides the force to keep them together. I have seen some blocks for walls that are very large--think a concrete lego brick the size of a bale of hay. Some I have seen have bumps on one side and dents on the other, so they stack and won't move horizontally, and gravity does the rest.
On a smaller scale, I wonder what could be done with structures that respond to other sources, such as thermal, and pH, or even blood chemistry, and how those could be used in the body.
We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
