We cordially invite you to visit us at Hall A3, Booth 417 at the LASER World of PHOTONICS in Munich from June 22 - 25, 2015.

At this leading international trade fair for the laser and photonics industry we will proudly present our exten-sion set for the mesoscale including a novel photoresist, brand-new soft-ware updates, and an ideally suited microscope-objective. Structures with dimensions in the millimeter range with yet submicron features can now be easily printed. A close collaboration between process-, application-, and software-develop-ment has enabled smart functional

software features that further push the limits of advanced 3D micro- printing!

Have a look at the multitude of ground-breaking new applications, ranging from 3D printed photonic wire bonds, lenses for micro-optics, bio engineer-ing and examples of maskless lithogra-phy or meso-scale parts.

Please don’t hesitate to make an appointment or just drop by at our booth, so we can discuss newest trends and developments within the laser and photonics industry.

Counterfeiting of goods has huge economic consequences with an esti-mated global loss of $654 billion per year. This negative economic impact hits many different product categories ranging from medicine, electronics and watches to counterfeit documents like money and IDs. [1]

To fight product counterfeiting, manufactures nowadays have many anti-counterfeit technologies avail-able. A whole industry is dedicated to provide security features that enable the authentication of products and deter product imitators based on dif-ficulty or costs to replicate these fea-tures.

Most common features today belong to the class of security level 1. These overt features can be authenticated by naked eye or tactile sense therefore being user verifiable without the need of additional tools. [2] Most prominent examples known to the public from many banknotes found around the world are holograms, color-flipping or fine-line prints. Recent developments incorporate transparent windows into polymer banknotes that con-tain a diffractive optical element. [3]

Fig. 1 Example of a colorful QR code con-sisting of diffractive dot arrays.

When illuminated with coherent light from a laser pointer, a previously hid-den image can be projected on a flat surface for authentication.

Fabrication of these features requires constructing a master using high- resolution lithography methods as a first step. This master is finally mass-replicated using stamping or roll-to-roll fabrication to get the security labels. Nanoscribe‘s high-resolution 2D and 2.5D patterning capabilities enable the mastering of high-resolution overt features like fine-line prints, diffrac-tive color prints or diffractive optical elements in one lithography step. The examples of the photonic color image [fig. 1] and the diffractive optical ele-ment [fig. 2] projecting our company logo were fabricated using a Photonic Professional GT to demonstrate the feasibility for these applications.

Nanoscribe is happy to welcome Harvard University (Cambridge, MA) amongst our users. At the end of April a Photonic Professional GT system has been set up in the Center for Nanoscale Systems (CNS). Under the direction of Dr. William L. Wilson, the center inves-tigates the development of nanoscale components and devices and their integration into large and complex interacting systems.

Nanoscribe is eager to see outstanding results coming up soon and wish the CNS at Harvard University a good start with their new key enabling tool for 3D and advanced 2D micro-fabrication tasks. This is how happy faces look like in a clean room after installation of a Photonic

Professional GT at Harvard University.

These days, the city of Karlsruhe located in Baden-Württemberg in Germany starts to celebrate its 300th birthday with a lot of events and parties. Nanoscribe congratulates its hometown with a very special present: Miniatures of Karlsruhe s most famous sights.

The castle and the pyramid were both printed on the micrometer scale by means of the Photonic Professional GT. 3D printing these structures is easy. You only need the

model data as STL-files and the special photoresist IP-S to start the process. After the part is printed, the castle has been sputter coated with a thin layer of gold to achieve the shiny appeal.

All details of the former residence of the margrave Karl Wilhelm von

Baden can be discovered now on the-impressive scale of 1:16,800! Nothing is missing, look upon the com-plexity of the tower, the filigree ramps or the numberless windowsills.

The second sight, the pyramid of Karlsruhe, was built in 1823 on the grave of the margrave and has got an original height of 6.8 meters. 3D printed on the nanometer scale you can now compare it to the width of a human hair!

Discover these tiny objects with the size of dust grains and be awed by our 3D printing capabilities at the Open Day of the Karlsruhe Institute of Technology (KIT) at the Campus South on June 27, 2015.

We are very proud to announce that Nanoscribe is nominated for the “Deutscher Gründerpreis” (EN: “ German Founders’ Award”) 2015 in the category “Aufsteiger” (EN: “rising star”).

The company hence represents one of the most successful start-ups in recent years in Germany. The experts of the jury were equally impressed by both the ground-breaking capabilities of Nanoscribe’s 3D printers for the nano- and micrometer scale and the entre-preneurial expertise of the founders.

OUTSTANDING PERFORMANCE

The jury, which votes on behalf of the German Founders’ Award partners, stern magazine, the Sparkasse savings bank network, Europe’s largest broad-casting TV station ZDF and Porsche, was impressed by how successfully the company had been able to estab-lish itself thanks to clear unique selling

points. The founders have developed a marketable product from the results of their basic research and positioned it on the world market. The company idea arose on the initiative of Profes-sor Martin Wegener, the work group leader at the Institute for Nanotech-nology and the Institute for Applied Physics at the Karlsruhe Institute of Technology (KIT). It was here that the later co-founders Martin Hermatsch- weiler, Dr. Michael Thiel and Dr. Georg von Freymann (today professor at TU Kaiserslautern) were engaged in research together. These scientific findings, coupled with the entrepreneurial spirit of these four physicists, constituted the company’s foundation – Nanoscribe was born. It was the first spin-off from the KIT at the end of 2007.

The head of research and develop-ment, Dr. Michael Thiel says about the nomination: “I hope that our example will encourage other scientists from

basic research to develop marketable products.”The award ceremony will take place on June 30, 2015 in Berlin. You can watch the ceremony via web streaming: www.deutscher-gruenderpreis.de/
