“…[59] A more universal and controllable method, however, is magnetically assisted slip casting (MASC) [60] or magnetically assisted 3D printing. [61,62] Ferrand et al [60] demonstrated that alumina nanoplatelets coated with superparamagnetic iron oxide nanoparticles could be assembled by applying an external rotating magnetic field. As shown in Figure 5A, the suspension was placed in a gypsum mold to remove solvent to form a layer of jammed and fixed assembled nanoplatelets during the slip casting process.…”

“…Kokkinis et al [61] demonstrated that composites with diverse components, complex shape, and varying orientation of building blocks could be fabricated by multimaterials' magnetically assisted 3D (MM-3D) printing. As shown in Figure 5C, their composite was printed with two kinds of materials: texturing ink (beige) with alumina platelets and shaping ink (gray).…”

Over the eons of evolutionary time, natural materials, including nacre, bone, lobster cuticle, and many others, developed delicate multiscale structures demonstrating outstanding properties. These natural materials provide endless inspiration for the fabrication of novel bioinspired structural materials. Extensive research has revealed the mechanism responsible for natural materials' properties and shows that high-performance structural materials could be fabricated via bioinspired strategies. [1][2][3][4][5][6][7][8][9][10] With the quest to develop novel bioinspired materials, it is essential to refine some basic scientific principles that can guide bioinspired fabrication.Recent research has indicated that the amplification of natural materials' mechanical properties far beyond those of the components that comprise them originates mainly from: i) a hierarchical micro-/nanoscale architecture and ii) abundant effective interface interactions. Here, we follow the roadmap of "discovery, invention, and creation," as shown in Figure 1, to give insight into the development of bioinspired structural materials. In the "discovery" section, natural materials are described as a source of inspiration. Bioinspired nanocomposites can be invented to mimic or even to surpass natural materials' attributes, as described in the "invention" section. We illustrate how the basic principles could work for bioinspired nanocomposites with different building blocks and fabrication approaches. Finally, in the "creation" section, we review novel multifunctional nanocomposites with properties that natural materials rarely possess. To provide a vision and inspiration for future research, we conclude with our perspectives on new and promising directions in the field, along with problems remaining to be solved. Discovery: Natural Materials Orderly Hierarchical ArchitecturesNatural materials are made at ambient temperatures from a relatively small number of ingredients that exhibit rather meager properties. Almost all of them are composites with orderly hierarchical architectures that arrest crack propagation, thus preventing catastrophic failure. Insight into the architecture of a typical natural material is the key to understanding the superiority of the biomimetic strategy for making novel synthetic materials.Natural materials, including nacre, bone, and the lobster cuticle, exhibit excellent mechanical properties, combining high strength and toughness. Such materials have the added benefit of being light in weight. These advantageous features are due to such natural materials' orderly hierarchical architectures and abundant interface interactions. How to utilize these design principles created by nature to fabricate high-performance bioinspired nanocomposites remains a great research challenge. A logical roadmap for developing these nanocomposites can be described as "discovery, invention, and creation." Here, the discovery of the relationship between natural materials' design principles and such materials' extraordinary mechanical proper...

Recent advances in materials science and three-dimensional (3D) printing hold great promises to conceive new classes of multifunctional materials and components for functional devices and products. Various functionalities (e.g., mechanical, electrical, and thermal properties, magnetism) can be offered by the nano-and micro-reinforcements to the non-functional pure printing materials for the realization of advanced materials and innovative systems. In addition, the ability to print 3D structures in a layer-by-layer manner enables manufacturing of highly-customized complex features and allows an efficient control over the properties of fabricated structures. Here, the authors present a brief overview mainly over the latest progresses in 3D printing of multifunctional polymer nanocomposites and microfiber-reinforced composites including the benefits, limitations, and potential applications. Only those 3D printing techniques that are compatible with polymer nanocomposites and composites, that is, materials that have already been used as printing materials, are introduced. The very hot topic of 3D printing of thermoplastic composites featuring continuous microfibers is also briefly introduced.

“…The International Technology Roadmap for Semiconductors (ITRS 2.0, see http://www.itrs2.net/itrs-reports.html) calls for '3D Power Scaling' as the next phase of silicon integrated circuit technology. These technologies, coupled with recent advances in 3D printing 19,20 and surface mounting technologies (such as magnetic field assisted assembly) 21 are anticipated to be the next enabler of manufacturing systems-on-a-chip, XYZ-on-a-chip, lab-on-a-chip, etc.…”
