From Visioneers to 3D Printing – Where is Nanotech Going?

10 January 2013 Cleantech & Nano Publication

Another interesting nanotechnology book recently appeared, The Visioneers, by W. Patrick McCray, 2013, 323 pages, $29.95 hardback at Barnes & Noble (“How a group of elite scientists pursued space colonies, nanotechnologies, and a limitless future”). One focus in this book is on the history of nanotechnology up to around 2004, including the role of Eric Drexler and Richard Smalley and their famous debate. The origin of the NNI is briefly covered. The multiple strands of nanotechnology are explored, ranging from futuristic concepts to advanced materials science for making products now.  Tensions between different nanotech philosophies and groups are explored. Good read, although it would have been interesting if more content had been provided for after 2004. Also, nanotechnology is only one of two conveyed stories of visioneering.

Also, 3D printing seems to be the rage these days in the technical and general media. The USPTO will hold a special session on 3D printing on January 23,2013. The 3D printing company ExOne is announcing an IPO attempt. In 3D printing, thin layers are built on one another. Nanotechnology connects in the materials used for 3D printing, as well as the notion of making thinner and thinner layers. Where is nanotechnology going? It is impacting personalized medicine and energy. 

Clearly, one visioneering answer also now arising is in 3D printing.
