Nanoscale physical materials that can be automatically assembled into useful configurations by computer instructions could usher in a new era in manufacturing.
New nano-materials with unique properties and functions could significantly change many segments of the materials manufacturing industries, impacting on the way goods are manufactured and designed. Using a variety of electronic, mechanical, and biological techniques, nanoscale building blocks, with precisely controlled size and composition could be assembled into larger structures in a process called nanostructuring.
Nanoscale manufacturing could also enable the development of structures not previously observed in nature. It could allow us to synthesize materials by design, develop new bio-inspired materials, introduce cost-effective and scalable production techniques, and determine at the nanoscale the reasons for materials failure. Potential applications of nanoscale manufacturing include the following:
- Manufacturing of nanostructured metals, ceramics, and polymers in exact shapes without machining
- Improved printing brought about by nanometer-scale particles that have the best properties of both dyes and pigments
- Nanoscale cemented and plated carbides and nanocoatings for cutting tools and for electronic, chemical, and structural applications
- Nanofabrication on a chip with high levels of complexity and functionality
- Proliferation of lighter, stronger programmable materials to be used in everything from construction to computing and health care
- Advent of a new manufacturing paradigm based on small-scale molecular assembly
- Reductions in life-cycle costs of materials due to lower failure rates
- Emergence of innovative devices based on new principles and architectures
- Possible decline of traditional manufacturing regions and emergence of new ones in developed and developing economies
- Current work by researchers at Carnegie Mellon University on 'claytronics', the term they use to describe using reconfigurable nanoscale robots (claytronic atoms, or 'catoms') to form much larger-scale machines or mechanisms
- Completion of preliminary design and modeling studies by General Dynamics Advanced Information Systems of a useful self-replicating system (SRS) -- a system of kinematic cellular automata (KCA) cells that are configured as a limited implementation of a universal constructor
What to Watch:
- IBM or Motorola announces commericial availability of self-assembled nanocrystal flash chips (both have lab prototypes now).
- A nanomaterials research laboratory demonstrates self-assembling nanowires and a 'nanofactory' capable of building a larger version of itself.
- A biological research laboratory demonstrates self-assembling materials, which mimic biologic growth processes.
- Rapid development of microscale manufacturing, primarily for semconductors, during the 1970s, 1980s, and 1990s

At A Glance:
About this outlook: An outlook is an internally consistent, plausible view of the future based on the best expertise available. It is not a prediction of the future. The AT-A-GLANCE ratings suggest the scope, scale, and uncertainty associated with this outlook. Each outlook is also a working document, with contributors adding comments and edits to improve the forecast over time. Please see the revision history for earlier versions.

Chris Phoenix (CRN's Director of Research):
A couple of clarifications:
CRN's main website is http://crnano.org. Our blog has lots of good stuff too--thanks, Bleyddyn.
This article appears to talk about a broader set of manufacturing techniques, which will start by building less advanced (though still useful/interesting) products. The "sweet spot" that CRN focuses on is the use of nanoscale tools to build more nanoscale tools by covalent synthesis. That promises a number of interesting implications including low-cost fully-automated exponential manufacturing.
Several trends are leading toward that sweet spot. CRN's timeline is pretty aggressive, but I've studied this for a decade and a half, and I believe most nanotechnologists haven't fully realized the extent to which the molecular manufacturing approach can simplify a lot of nanoscale problems.
In any case, it's not either-or, it's a continuum.
