Research
Computational Design
We support designers in their discovery of new, innovative solutions to engineering tasks, and help them gain a better understanding of solution spaces through the interactive and automated generation of optimized design alternatives. For example, crystallographic network topologies are analyzed from a structural point of view for the design of architected structures for engineering applications. In the area of origami-based structures, computational methods and mathematical conditions are developed to determine origami patterns.
Design for Additive Manufacturing (AM)
We investigate new design methods for AM, e.g. supporting conceptual design with design heuristics for AM and 3D printed objects to visualize each heuristic. On the computational side, we develop new representations and optimization methods for multi-material distribution, anisotropy of mechanical properties and topology, shape and size optimization. This research couples computational design and the mechanical testing of 3D printed materials and optimized structures, for example the design and optimization of shape-morphing structures that are actuated pneumatically. An application-driven topic includes the multi-material optimization of personalized, artificial spinal discs that are 3D printed.
Designing Novel Structures and Machines with 4D Printing
4D printing is the 3D printing of functional materials, e.g. in a multi-material process, to create parts that actively reconfigure themselves in response to the environment. This creates a new paradigm for the design of novel machines that do not use conventional components. We investigate how we can design new structures and machines that can morph their shape in response to temperature change. We also advance the state-of-art in the design of novel machines that use 3D printed, bistable mechanisms as actuators to assemble themselves, propel a swimming robot and automatically deploy a solar panel.
Development Engineering
A new research area focuses on design for low-resource settings. An initial focus is the design of a new, low-cost mechanical ventilator for field use. In collaboration with industry, we are also developing a new sustainable design and fabrication process for dwellings made of mortarless Compressed Earth Bricks (CEB).
