She is acclaimed for her interdisciplinary approach to teaching and research. Kathrin‘s expertise in integrating digital tools into education is particularly attributed to her involvement in the DigiMath4Edu project at the University of Siegen, Germany. Within this project, she concentrated on advancing competencies in 3D printing as part of mathematics education. 

Kathrin bridges the gap between educational research and teaching methodologies, for both pre-service and in-service teacher training in STEM.

Prusa Research was founded as a one-man startup in 2012 by Josef Prusa, a Czech hobbyist, maker and inventor - and now one of the most famous names in the 3D printing industry.

Josef found his passion for 3D printers as a student of University of Economics in Prague. That was in 2009. Back then, he considered 3D printing to be nothing but a hobby, an amazing new technology open to changes and improvements. Josef then joined the open-source RepRap project and the rest is history.
