Particles so small that only the newest and most sensitive instruments can see and study them are being used to create new materials and devices that could revolutionize everything from drug delivery to sunscreens. That encouraging revelation comes from Robert W. Hunt, a professor of materials science and engineering at Rensselaer Polytechnic Institute (Troy, NY). Hunt heads a committee for the World Technology Evaluation Center that the National Science Foundation and other federal agencies have contracted to conduct a two-year, $400,000 study of nanotechnology around the world. Nanotechnology, a rapidly expanding scientific field, is in an early stage of development not unlike that of computer and information technology in the 1950s. Siegel, who coined the phrase "nanophase" materials, explains that new tools are letting scientists and engineers characterize and manipulate materials at the nanoscale level. For instance, he works with materials comprised of common atoms arranged in grains less than 100 nm in diameter--10,000 times smaller than grains in conventional materials. Researchers use them as building blocks to create materials with entirely new properties. Recently, members of Siegel's committee spent a week in Japan and in western Europe visiting sites conducting research on such materials. A report on their findings is due out this spring.

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
