“…The commercial magnetic-polymer composite filament Magnetic Iron PLA purchased from Proto-Pasta [53] was used to print the magnetic thermo-seeds samples. The filament consists of 40 wt.% of iron microparticles (40 µm in size) loaded in a polylactic acid (PLA) polymer matrix (NatureWork's 4043D Ingeo Biopolymer) [54], [55].…”

Magnetic tissue scaffolds are a promising powerful tool for performing interstitial tumor hyperthermia against the residual bone cancer cells, after surgical intervention. The design of the implant architecture is crucial for several biomedical requirements. However, to date, the influence of implant topology on the hyperthermia treatment outcome has never been assessed. Furthermore, the heating ability is a function of sample mass and geometry. In this work, a simple methodology for designing biomimetic scaffolds using triply periodic minimal surfaces is presented. A set of geometries is 3D printed by fused deposition modeling, using a commercial poly-lactic acid filament filled with magnetite particles, never tested for biomedical applications. Magnetic scaffolds were thoroughly characterized by performing static magnetic measurements, differential scanning calorimetric and thermogravimetric analysis, but, mostly, by carrying out calorimetric measurements to determine their hyperthermic potential under different experimental conditions. Numerical multiphysics simulations with a commercial finite element software were performed, resulting in good agreement with the measurements. The scaffolds were exposed to a magnetic field with 15 mT strength, working at 400 kHz, in air, and the surface temperature was recorder using infrared camera. The manufactured magnetic scaffolds can increase the temperature above 41°C (about 54-57°C), in 40-60 s. In distilled water, for a 30 mT magnetic field and 400 kHz, the temperature was recorded using an optic fiber and we observed that all the sample could be used as thermo-seed for cancer therapy. Finally, the scaffolds were tested in agarose phantoms and their hyperthermic potential was quantified.

Fe-based amorphous materials offer new opportunities for magnetic sensors, actuators, and magnetostrictive transducers due to their high saturation magnetostriction (λs = 20–40 ppm) and low coercive field compared with polycrystalline Fe-based alloys, which have high magnetostriction but large coercive fields and Co-based amorphous alloys with small magnetostriction (λs = −3 to −5 ppm). Additive layer manufacturing (ALM) offers a new fabrication technique for more complex net-shaping designs. This paper reviews the two different ALM techniques that have been used to fabricate Fe-based amorphous magnetic materials, including the structural and magnetic properties. Selective laser melting (SLM)—a powder-bed fusion technique—and laser-engineered net shaping (LENS)—a directed energy deposition method—have both been utilised to fabricate amorphous alloys, owing to their high availability and low cost within the literature. Two different scanning strategies have been introduced by using the SLM technique. The first strategy is a double-scanning strategy, which gives rise to maximum relative density of 96% and corresponding magnetic saturation of 1.22 T. It also improved the glassy phase content by an order of magnitude of 47%, as well as improving magnetic properties (decreasing coercivity to 1591.5 A/m and increasing magnetic permeability to around 100 at 100 Hz). The second is a novel scanning strategy, which involves two-step melting: preliminary laser melting and short pulse amorphisation. This increased the amorphous phase fraction to a value of up to 89.6%, and relative density up to 94.1%, and lowered coercivity to 238 A/m. On the other hand, the LENS technique has not been utilised as much as SLM in the production of amorphous alloys owing to its lower geometric accuracy (0.25 mm) and lower surface quality, despite its benefits such as providing superior mechanical properties, controlled composition and microstructure. As a result, it has been commonly used for large parts with low complexity and for repairing them, limiting the production of amorphous alloys because of the size limitation. This paper provides a comprehensive review of these techniques for Fe-based amorphous magnetic materials.

3D printing (additive manufacturing (AM)) has enormous potential for rapid tooling and mass production due to its design flexibility and significant reduction of the timeline from design to manufacturing. The current state-of-the-art in 3D printing focuses on material manufacturability and engineering applications. However, there still exists the bottleneck of low printing resolution and processing rates, especially when nanomaterials need tailorable orders at different scales. An interesting phenomenon is the preferential alignment of nanoparticles that enhance material properties. Therefore, this review emphasizes the landscape of nanoparticle alignment in the context of 3D printing. Herein, a brief overview of 3D printing is provided, followed by a comprehensive summary of the 3D printing-enabled nanoparticle alignment in wellestablished and in-house customized 3D printing mechanisms that can lead to selective deposition and preferential orientation of nanoparticles. Subsequently, it is listed that typical applications that utilized the properties of ordered nanoparticles (e.g., structural composites, heat conductors, chemo-resistive sensors, engineered surfaces, tissue scaffolds, and actuators based on structural and functional property improvement). This review's emphasis is on the particle alignment methodology and the performance of composites incorporating aligned nanoparticles. In the end, significant limitations of current 3D printing techniques are identified together with future perspectives.
