TrussFormer is a research project that allows non-expert users to create large, moving structures with the help of smaller parts, i.e., soda bottles, and 3D printing.

During my master’s studies at the Hasso-Plattner-Institute, I was involved in this project that combines Human-Computer-Interaction and Mechanical Engineering. Under the supervision of PhD student Robert Kovacs, Prof. Dr. Patrick Baudisch and others, a group of master’s students created the interactive editor. I was fully responsible for creating the complex hinge structures in OpenScad and partly responsible for the Web-technology-based UI in the fast-paced research environment.

Our work was published at one of the most impactful Human-Computer Interaction conference UIST 2018 in Berlin, Germany
