At the Photonics West, the leading international fair for photonics taking place in San Francisco (USA) this week, Nanoscribe GmbH, a spin-off of Karlsruhe Institute of Technology (KIT), presents the world's fastest 3D printer of micro- and nanostructures.
With this printer, smallest three-dimensional objects, often smaller than the diameter of a human hair, can be manufactured with minimum time consumption and maximum resolution. The printer is based on a novel laser lithography method.
"The success of Nanoscribe is an example of KIT's excellent entrepreneurial culture and confirms our strategy of specifically supporting spin-offs. In this way, research results are transferred rapidly and sustainably to the market," says Dr.
Peter Fritz, KIT Vice President for Research and Innovation. In early 2008, Nanoscribe was founded as the first spin-off of KIT and has since established itself as the world's market and technology leader in the area of 3D laser lithography.
Last year, 18 spin-offs were established at KIT. The 3D laser litho-graphy systems developed by Nanoscribe - the spin-off can still be found on KIT's Campus North - are used for research by KIT and scientists worldwide.
Work in the area of photonics concentrates on replacing conventional electronics by optical circuits of higher performance. For this purpose, Nanoscribe systems are used to print polymer waveguides reaching data transfer rates of more than 5 terabits per second.
Biosciences produce tailored scaffolds for cell growth studies among others. In materials research, functional materials of enhanced performance are developed for lightweight construction to reduce the consumption of resources. Among the customers are universities and research institutions as well as industrial companies.
Increased Speed: Hours Turn into Minutes
"We are revolutionizing 3D printing on the micrometer scale. Precision and speed are achieved by the industrially established galvo technology. Our product benefits from more than one decade of experience in photonics, the key technology of the 21st century," says Martin Hermatschweiler, the managing director of Nanoscribe GmbH.
Mechanism: Two-photon Polymerization
Depending on the photosensitive material chosen, the exposed or unexposed volume only is dissolved. After a developer bath, these written areas remain as self-supporting micro- and nanostructures.
Just as floor tiles must be joined precisely, the respective scanning fields have to be connected seamlessly and accurately. By the so-called stitching, areas can be extended nearly arbitrarily.
