Polymer bonded permanent magnets find significant applications in a multitude of electrical and electronic devices. In this study, magnetic particle-loaded epoxy resin formulations were developed for in-situ polymerization and material jetting based additive manufacturing processes. Fundamental material and process issues like particle settling at room temperature and elevated temperature curing, rheology control and geometric stability of the magnetic polymer during the thermal curing process are addressed. Control of particle settling, modifications in rheological behavior and geometric stability were accomplished using an additive that enabled the modification of the formulation behavior at different process conditions. The magnetic particle size and additive loading were found to influence the rheological properties significantly. The synergistic effect of the additive enabled the developing of composites with engineered magnetic filler loading. Morphological characterization using scanning electron microscopy revealed a homogenous particle distribution in composites. It was observed that the influence of temperature was profound on the coercive field and remanent magnetization of the magnetic composites. The characterization of magnetic polymers and composites using rheometry, scanning electron microscopy, X-ray diffraction and superconducting quantum interference device (SQUID) magnetometry analysis enabled the correlating of the behavior observed in different stages of the manufacturing processes. Furthermore, this fundamental research facilitates a pathway to construct robust materials and processes to develop magnetic composites with engineered properties.

Polymer composites containing ferromagnetic fillers are promising for applications relating to electrical and electronic devices. In this research, the authors modified an ultraviolet light (UV) curable prepolymer to additionally cure upon heating and validated a permanent magnet-based particle alignment system toward fabricating anisotropic magnetic composites. The developed dual-cure acrylate-based resin, reinforced with ferromagnetic fillers, was first tested for its ability to polymerize through UV and heat. Then, the magnetic alignment setup was used to orient magnetic particles in the dual-cure acrylate-based resin and a heat curable epoxy resin system in a polymer casting approach. The alignment setup was subsequently integrated with a material jetting 3D printer, and the dual-cure resin was dispensed and cured in-situ using UV, followed by thermal post-curing. The resulting magnetic composites were tested for their filler loading, microstructural morphology, alignment of the easy axis of magnetization, and degree of monomer conversion. Magnetic characterization was conducted using a vibrating sample magnetometer along the in-plane and out-of-plane directions to study anisotropic properties. This research establishes a methodology to combine magnetic field induced particle alignment along with a dual-cure resin to create anisotropic magnetic composites through polymer casting and additive manufacturing.

Magnetic material is the key component in lot of electromagnetically-based optical to microwave applications. In the case of radio-frequencies/microwave applications, passive components are developed using planar design to facilitate their fabrication while 3D geometries are the best shapes to improve components properties. But nowadays, 3D printing technologies are coming up in industries and 3D design of passive components grows in interest. But 3D shaping of magnetic material remains a problem which has to be solved before considering industrial implementation.In this work, we demonstrate the possibility of 3D shaping ferrite magnetic powder using Selective laser melting/sintering in ambient air. A ferrimagnetic powder of Yttrium Iron Garnet (YIG) was used to form a 10-layers stack of magnetic material. A simple method for small surface (10x10mm²) deposition of powder was developed by dispersing the YIG powder into ethanol. A drop is then deposited on top of a substrate. Ethanol evaporates and an homogeneous layer is obtained. A 1064nm-nanosecond laser combined to a scanning lens is used to irradiate the powder layer and induce melting/sintering of the powder at ambient temperature and in ambient air. Chemical and structural changes induced by the laser process were studied using Raman spectroscopy. Results show that a part of the YIG was decomposed into a weakly magnetic phase of Fe3O4. Vibrating Sample Magnetometry was then used to compare the magnetic behavior of the YIG multilayer and the YIG powder. The multilayer always exhibit a magnetic behavior whatever the substrate is: YIG powder, YIG bulk or Al bulk.
