article⁄Fluid Equilibrium: Material Computation in Ferrofluidic Castings (2018)
abstract⁄We present a computationallybased manufacturing process that allows for variable pattern casting through the use of ferrofluid a mixture of suspended magnetic nanoparticles in a carrier liquid. The capacity of ferrofluid to form intricate spike and labyrinthine packing structures from ferrohydrodynamic instabilities is well recognized in industry and popular science. In this paper we employ these instabilities as a mold for the direct casting of rigid materials with complex periodic features. Furthermore, using a bitmapbased computational workflow and an array of highstrength neodymium magnets with linear staging, we demonstrate the ability to program the macroscale pattern formation by modulating the magnetic field density within a single cast. Using this approach, it is possible to program specific patterns in the resulting cast tiles at both the micro and macroscale and thus generate tiled arrays with predictable halftonelike image features. We demonstrate the efficacy of this approach for a variety of materials typically used in the architecture, engineering, and construction industries AEC including epoxys, ceramics, and cements.
