Structural porous materials are important in the skeletal structure of the human body as they provide support along with weight reduction and storage of minerals. Mimicry of these porous structures has been attempted using ceramics to simulate the stiff and brittle nature of the biogenic hydroxyapatite in bone. One such method to create these mimetic structures is freeze casting, where ice crystals are used to template a ceramic scaffold resulting in a porous structure. We integrated the freeze casting process into a Helmholtz coil to induce a uniform magnetic field to control surface-magnetized ceramic particles. This method of freeze casting can lead to improved mechanical properties through magnetic particle manipulation. This bioinspired material provides a way to closer mimic the mechanical characteristics of bone.
