3D printing of Architected polymer foams New technique makes cover of Advanced Materials

In article number 1904668, Claas Willem Visser, Jennifer A. Lewis, and co‐workers describe the fabrication of architected polymer foams by “direct bubble writing”. In this process, bubbles are ejected into air, deposited onto a substrate, and then photopolymerized with UV light, and open‐ and closed‐cell foams with locally graded densities can be printed into 3D objects such as 3D lattices, shells, and out‐of‐plane pillars.

The technique was developed at Harvard University, and will be continued by first author Claas Willem Visser who recently re-joined the UT as a staff member of the Engineering Fluid Mechanics group led by Kees Venner.
