Claas Willem Visser develops multi-scale functional materials, by converting fluid droplets or bubbles into solid "building blocks" and stacking these. The multi-scale nature of these materials enables optimizing their mechanical, acoustic, electrical, and biological properties for various applications.

From 2016 to 2018, Visser worked as a Rubicon Post-Doctoral Fellow at the Harvard John A. Paulson School of Engineering and the Wyss Institute for Biologically Inspired Engineering. Here, he developed a new method for additive manufacturing of polymer foams in the lab of Prof. Jennifer A. Lewis.

Before that, as a post-doc at the University of Twente, Visser co-developed a new technology for particle fabrication and 3D printing named "In-air microfluidics". This technology is now commercialized in spinoff company IamFluidics, of which Visser is co-founder and chief scientific officer.

Visser pursued his Ph.D. (2011-2015) under the supervision of Prof. Chao Sun (now at Tsinghua University)  and Prof. Detlef Lohse, in the Physics of Fluids group at the University of Twente. Here, he contributed to fundamental studies on micro-scale droplet impact as well as applications such as laser-induced transfer of metals and droplet-based cell deposition.

From 2006 to 2011, Visser worked at Tata Steel Research, Development, and Technology as a researcher and project leader. He initiated several national and international research projects on hot rolling of metal strip.

Visser received his MSc degree in Applied Physics from the University of Twente in 2006, and completed his internship in Prof. Ke-Qing Xia's group at the Chinese University of Hong Kong.

The Fluid Mechanics for Functional Material team creates new materials from scratch. Here, droplets or particles are used as "building blocks" that add functionality to 3D-printed pieces in programmable shapes.

Our research focuses on creating the right building blocks and stacking them into the right shape, for example by understanding and controlling the impact of micro-scale droplets [1,2]. Together with collaborators, this strategy has advanced multi-scale tissue engineering [3], rapid fabrication of complex particles for chemical reactions [3,4], and 3D printed micro-sensors in gold and platinum [5,6].

Upcoming projects will focus on aero-acoustic materials, thin-film flows, and foams. These projects are pursued in close collaboration with experts who have deep knowledge of the application field, either at the University of Twente, in companies or with (inter)national collaborators.
