Printer Writes Micro 3D Objects: "University of Illinois researchers have come up with a new type of quick-setting three-dimensional ink that works a bit like a microscopic tube of toothpaste. The researchers' printer robotically deposits a continuous, elastic-like ink filament into a liquid rather than putting ink drops onto a surface.
The filament hardens in the liquid rapidly enough to allow for printing three-dimensional structures that have features like unsupported spanning elements. The process yields complete three-dimensional structures in about five minutes, and provides resolutions that are close to two orders of magnitude finer than existing methods, according to the researchers. The researchers' prototype has nozzles that vary in diameter from five microns to 0.5 microns. A micron is one thousandth of a millimeter.
Because the resolution is so high, the process has the potential to produce templates for structured materials, like photonic band gap materials used to control light, microfluidic devices used for biological and chemical testing, and bioscaffolds for tissue engineering." 11:08:26 PM
Nano-Hive: Nanospace Simulator:
"Nano-Hive is a modular simulator used for modeling the physical world at a nanometer scale. The intended purpose of the simulator is to act as a tool for the study and development of nanotech entities." Version 1
is for a single-user desktop, version 2 is planned to be distributed, possibly using Globus. 8:59:02 AM
