Magnetic nanoparticles have recently been applied to facilitate in vivo capture of small molecule chemotherapeutics. Removal of these nanoparticles after chemotherapeutic capture is an unresolved problem. In particular, capture devices must be magnetizable, have high surface areas for particle uptake, and minimize flow disruption. A potential solution to this issue involves additive manufacturing (AM) of magnetic alloys. A recent method developed for metal AM, hydrogel infusion AM (HIAM), has demonstrated the ability to form lattices with a range of metal alloy compositions. The magnetic and microstructural properties of materials synthesized through this pathway are still poorly understood. To further the knowledge of these properties as well as generate biocompatible magnetic lattices, we use HIAM to form iron, iron-nickel, and copper-nickel-iron lattices. We characterize the magnetic properties of these samples by vibrating sample magnetometry and perform microstructural analysis via powder X-ray diffraction, energy dispersive X-ray spectroscopy, and electron backscatter diffraction.
