Main activities
Scientific context:
3D printing by filament fabrication makes it possible to combine multiple materials of different properties within a same part. The properties of interest cover for instance flexibility, conductivity, fiber-reinforcement as well as filament which properties vary under external stimulus.
These properties are directly impacted by the orientation of the deposition of the filaments, leading to anisotropic behaviors. Thus, we can envision producing parts with controlled property fields, that deform and react to the environment due to how the filament deposition has structured gradients of properties within their volume [1,2]. Unfortunately, there is currently only few methods available to optimize for and exploit these promising possibilities.
Topic:
We will explore how to use topology optimization methodologies to design parts fabricated with fused filament, using one or multiple materials, where the orientation of the paths drives the final properties of the object. We will consider this problem first for fabricating planar plates, and then for the fabrication of non-planar shells using a robotic 3D printing platform. The optimization framework will build upon our work on phasor fields, allowing to optimize deposition trajectories to obtain the target properties once the objects are fabricated.
