3D Printing of Microscale Parts for Prototyping, Tooling and Production


Additive manufacturing based on two-photon polymerization (2PP) has evolved as the new standard for microfabrication. Its ultra-high resolution, design freedom, implementation along easy workflows and robust processes facilitates the reliable fabrication of almost arbitrary three-dimensional (3D) objects with minimal feature sizes down to 100 nm.

This addresses today’s challenges of rapid innovation cycles in the prototyping phase of research & development as well as the ever shortening turnaround times of tools needed for large scale fabrication based on replication techniques. This e.g. empowers the production via nanoimprinting or injection molding based on polymer masters and their inverse nickel shim replicas.
The combination of these benefits is especially revealed among innovation leaders in academia and industry. The broad range of technical use cases is especially appreciated where flexibility is desired and usability required, i.e. in multi-user facilities. The 2PP based devices match capabilities between electron-beam lithography and UV direct laser writing on the one side and 3D printing on the other side – yet with 100x higher resolution compared to conventional SLA-based 3D printers. This opens completely new possibilities not addressable prior to the ascend of 2PP based systems – paving the path for disruptions in industry and ground-breaking research in science.

The talk highlights some of the latest achievements and major breakthroughs in recent years, e.g. in the fields of optics and photonics such as e.g. micro lens arrays, diffractive optical elements (DOE) and challenges in the information and communication technology for the production of photonic circuits and MEMS devices. Individualization and miniaturization are further drivers of innovation especially in the field of biomedical devices.


Martin Hermatschweiler is co-founder and CEO of Nanoscribe GmbH ever since the company was founded in 2007. His main task is stimulating the company's positive development, particularly through the development of new markets. He studied physics in Ulm and Karlsruhe and gained extensive expertise in laser based patterning of polymers as well as surface coating techniques based on semiconductor processes in his scientific career. He holds several patents and was chosen by the business magazine "Capital" among Germany’s 40 most-talented entrepreneurs younger than 40 years old (2016).

Martin Hermatschweiler studied physics in Ulm and Karlsruhe, Germany, where he worked as a scientist at the Institute of Applied Physics at the Karlsruhe Institute of Technology (KIT), investigating 2D and 3D photonic crystals fabricated by direct laser writing as well as holographic lithography. His main assignment was the conversion of 3D polymer structures into silica and silicon under supervision of Prof. Dr. Martin Wegener. Martin Hermatschweiler leads the company Nanoscribe GmbH as CEO since the initialization of the business idea early in 2007.

Under his guidance, business has been built up from scratch starting up with originally three employees. The company runs profitable since 2010 and is debt-free since 2012. The growth is funded from operating cash-flow. The compound average growth rate (CAGR) of the revenues exceeded 4% in the last 5 years. Today, Nanoscribe is a multinational medium-scaled enterprise with more than 60 employees.
