The 3D brick approach to self-assembly at the nanoscale is based on short synthetic strands of DNA that form building blocks, which self-assemble into 100 different, precise 3D shapes such as letters and numbers. Like the models of 80 of these shapes shown here, each unique shape measures about 25 nm per side.
Because all of this work is still in R&D it might be easy to dismiss it as blue-sky. But I discovered while doing the background research for this article that many of these projects have been underway for several years, and much of what's being done now is second- or even third-generation R&D. There's an awful lot of brains and money aimed at developing self-assembling. self-reconfiguring robots. I came away with the feeling that the future is going to be very different, indeed.
Thanks, Rob. Yes, it's already starting to look like robots are replacing cheap labor again, even in China. It's been reported that Foxconn plans to "solve" it's widely publicized labor problems by replacing humans with millions of robots:
Some of the biggest self-assembled building blocks and structures made from engineered DNA have been developed by researchers at Harvard's Wyss Institute. The largest, a hexagonal prism, is one-tenth the size of an average bacterium.
Arevo Labs' end-production 3D printing technology for carbon composites includes a high-temperature, filament fusion printer head design and firmware for use with the company's new carbon fiber and nanotube reinforced high-temperature matrix polymers like PEEK.
Stratasys will buy Solid Concepts and Harvest Technologies and combine them with its RedEye service business. The plan takes aim at end-production manufacturing and will create one of the biggest commercial 3D printing and AM service bureaus.
The International Federation of Robotics reports that global sales of industrial robots decreased by 4% in 2012 over 2011. The biggest hit was electrical/electronics manufacturing, down by 13%; but by region, the Amerficas did well.
