Project description

We have an open PhD position to study procedural, stochastic, and fabricable microstructures, with a controlled macroscopic physical behavior. These have important applications in soft robotics, health-care, and the mechanical engineering fields, for instance for the design of deformable, lightweight and porous parts. Further details can be found here.

We are looking for a PhD candidate with, ideally, background in the field of 3D printing, computer graphics and physical simulation. The candidate should be proficient with C++, have a competent background in physics and finite element methods, and ideally some experience with 3D printing and computer graphics.

We recently have proposed and investigated novel types of microstructures to trigger controllable elastic behaviors within 3D printed objects [1,2,3] (see figures below). Following this line of research, the PhD candidate will tackle exciting algorithmic and fabrication challenges for the fast and scalable synthesis of procedural microstructures, that can be freely graded and embedded into volumes.
