Electrospun Fields uses a six-axis robot to move and reorient a high-voltage electrospinning emitter around conductive three-dimensional scaffolds. The scaffold shapes the electric field, so fiber density, orientation, porosity, and thickness emerge from geometry, material, and deposition conditions. Demonstrations include non-planar membranes and steep-slope deposition, but the paper does not quantify improvement over fixed-axis deposition.
Key insights
- Electric fields can be effectively programmed as generative design conditions to guide material self-organization, leading to the emergence of complex 3D fibrous structures like minimal surfaces and tension-based catenaries.
- Scaffold geometry acts as a powerful modulator of electric field distributions, directly conditioning fiber density, alignment, and the formation of hierarchical structures within the electrospun material.
- Dynamic robotic manipulation of the electrospinning emitter is crucial for spatially programming electric fields and enabling fiber deposition across varied 3D topologies, including previously inaccessible concave features.
