Our systems deliver unprecedented speed and accuracy, enabling industries to accomplish manufacturing feats that were previously out of reach.
Our management team
2PP-3D printing has been transitioned from research labs to an industrially deployed tool for manufacturing polymeric micro-components by unmatched printing speed and throughput, revolutionizing manufacturing possibilities across industries such as med-tech, optics, and consumer electronics.
Since its founding in 2018, we have successfully built a globally operating high-tech company with the help of highly qualified employees from diverse educational backgrounds. As a globally operating company headquartered in Vienna, Austria, with a branch office in Boston, United States, we have installed systems at renowned industry leaders and leading research institutions from the West Coast of the United States to Australia.
In high-resolution 3D printing, the interplay between hardware, software, and resins has been and continues to be the key to producing reproducible and scalable micro-components. This concept has been reflected in our company structure and product portfolio from the very beginning. Despite this complexity, UpNano is a scalable company that invests more than 30% of its annual revenue in the development of new technology each year, in line with the company’s mission to establish high-resolution 3D printing based on two-photon polymerization as an industrial manufacturing method.

Statement from the CEO
As the CEO and one of the co-founders of UpNano, it gives me immense pleasure to offer you a glimpse into our world.
First and foremost, I want to emphasize that UpNano thrives on the expertise and dedication of an exceptional team of passionate experts. It’s this remarkable team that has propelled us to become a key player in the field of 2PP-3D printing within just five years! It’s this same team that has forged partnerships with leading universities and companies worldwide, collaborating with them as peers. With our dedicated team, we aim to deliver cutting edge 2PP technology, providing unparalleled support for your scientific and commercial micro and nanofabrication projects. We’re committed to collaborating closely with you, providing support at every stage of the process.
“At UpNano, excellence is not just a goal – it’s our standard. And we’re thrilled to have you on board as we continue to push the boundaries of high-resolution 3D printing.”
We strongly believe in the superiority of 2PP technology. Among all 3D printing technologies, we firmly believe that two-photon polymerization stands out as the most precise, flexible and reliable option.
Just consider its incredible volume coverage, spanning from 400 nm3 to 40 mm3 – a range exceeding 15 logarithmic steps! To put it into perspective, a typical high-quality SLA printer covers a volume range of 6 to 7 log steps. Our 2PP systems encompass a volume range a billion times larger than that of average 3D printers – a fact that truly stretches the limits of imagination.
The unrivaled speed of our print technology isn’t just groundbreaking for prototyping; it opens the door to scaling up and commercially manufacturing of high-precision micro-components. While other technologies struggle to achieve industry standard CP values above 1.5, we effortlessly reach CP values of 15 and beyond within similar print times. And when others grapple with the mechanical properties of their materials, we’ve pioneered methods for adapting standard ISO tests to the micro universe. At UpNano, we understand the exacting standards of manufacturing, and we’re fully equipped to deliver.
We look forward to hearing from you and inviting you to visit our application labs in our headquarters in Vienna (Austria) or in our US subsidiary in Cambridge (MA).
Sincerely, Bernhard Küenburg
Team of founders
The founding team around industry-experienced CEO Bernhard Küenburg can look back on more than ten years of experience in the field of multiphoton polymerization. Peter Gruber, CTO, and Aleksandr Ovsianikov with their extensive research background at TU Wien, have pioneered the development of multiple generations of high-resolution 3D printing systems. COO Denise Hirner joined the founding team with a background in materials and applications, utilizing the developed systems for lab-on-a-chip applications. Research focus and one of today’s unique selling points of the NanoOne printing platform is high-resolution bioprinting – 3D printing with living cells, thereby facilitating the combination of polymer material and cell research. All of this is made possible by the unmatched performance and technology of the system.

The castle on a pencil tip
The twin towers of the
castle fascinate at first sight
The pillars forming the right spire have a diameter of 950 nm, approximately 100 times thinner than the average human hair. Despite their microscale dimensions, these pillars exhibit exceptional structural integrity as they are perfectly straight and fulfill their weight-bearing function.
You will only believe it when you see it
Fabricated with remarkable precision using 2-photon lithography, the mini-castle showcases dimensions of 230x250x360 µm³ and astonishingly was printed in under six minutes.
Delve into the intricate details of its production process through the YouTube video.
Winner of Wiki Science Competition
A scanning electron microscope photo of the nanoscale 3D printed castle won first place in the 2017 Wiki Science Competition in Austria, demonstrating both its fascination and innovative manufacturing technology.
From the sketch to implementation
Designed by Daniela Mitterberger and Tiziano Derme of MäID in Graz, the miniature castle on a pencil tip pays creative homage to the Sutyagin House in Arkhangelsk, Russia. Once the residence of the local crime lord Nikolai Petrovich Sutyagin and his family, the 44-meter-high wooden marvel was considered the tallest of its kind but was demolished in 2008 after a legal dispute. Explore the artistic reinterpretation of the Sutyagin House in the pencil-tip castle, blending creativity and history on nanoscale.
