3D printing on the micrometer scale
Date:2/8/2013

s Turn into Minutes

By means of the new laser lithography method, printing speed is increased by factor of about 100. This increase in speed results from the use of a galvo mirror system, a technology that is also applied in laser show devices or scanning units of CD and DVD drives. Reflecting a laser beam off the rotating galvo mirrors facilitates rapid and precise laser focus positioning. "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

The direct laser writing technique underlying the 3D printing method is based on two-photon polymerization. Just as paper ignites when exposed to sunlight focused through a magnifying glass, ultra-short laser pulses polymerize photosensitive materials in the laser focus. 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.

Removing Barriers

By means of the galvo technology, three-dimensional micro- and nanostructures can be printed rapidly and, hence, on large areas in principle. At highest resolution, however, the scanning field is limited physically to a few 100 m due to the optical properties of the focusing objective. 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.
