Photonic Professional GT


High-speed printing of 3D micro- and nanostructures

The new generation of Nanoscribe´s 3D laser lithography systems, Photonic Professional GT, provides a fast and powerful platform for three-dimensional micro- and nanofabrication demands. The printing speed can be typically increased hundredfold by employing a novel laser lithography method, enabling large-area applications with dimensions up to the centimeter range. The tremendous speed-up of the writing process is driven by an embedded ultra-high precision galvo technology, which laterally deflects the laser focus position by use of a galvo mirror system.
Nanoscribe´s CEO Martin Hermatschweiler explains: “Our 3D printers were already unrivaled in precision and resolution, user-friedliness, and compactness. Now they also stand out due to their enormous speed. Just for comparison: Using the novel system, the time required for printing a minature-spacecraft (see "Application Video: 3D µ-Printing" on youtube) was reduced from hours to minutes without any loss in structure quality! Our customers will benefit tremendously from the extended range of applications of our new product.”
Additionally, the GT version of Photonic Professional is equipped with a new modular controller, which facilitates future hardware upgrades.

This video shows a realtime recording of the 3D micro printing process by two-photon polymerization. We start with the CAD model of a Hellcat spaceship from Wing Commander Saga and use our 3D printer Photonic Professional GT to print a polymer model on the microscale. The final structure is then inspected with a scanning electron microscope (SEM). Overall printing time was less than 50 seconds for the ship with dimensions 125µm x 81µm x 26.8µm (l x w x h). The length of the spaceship is approximately equal to the diameter of a human hair.
