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.

“…Moreover, aligned CNCs can be applied in many fields in addition to enhancing materials strength, such as to modify surface properties, for the fabrication of structure colors and advanced textiles as well as for tissue engineering. [3][4][5][6][7] Currently, CNCs can be oriented in an external electric field or magnetic field, as well as by mechanical shearing, spincoating, dip-coating, dry/wet spinning or electrospinning. [8][9][10][11][12] However, these techniques are generally limited on producing 1D or 2D structures, such as fibers or films, respectively.…”

Advanced materials with aligned cellulose nanocrystals (CNCs) have attracted much attention due to their remarkable mechanical and optical properties, but most of them still focus on 1D or 2D architectures. Herein, complex 3D architectures as pseudo catenoid hollow xerogels with aligned CNCs are prepared from dynamic hydrogels by mechanical stretching and air‐drying process. Aligned CNCs endow the pseudo catenoids with distinct birefringence in addition to reinforcement. The mechanical properties of pseudo catenoid architecture are revealed for the first time to be controlled at two stages on diverse length scales. Both the aligned CNCs on the nanoscale and the geometry of the xerogels affect the mechanical properties. The inwardly curved surface of the pseudo catenoid xerogel makes the structure conducive to energy dissipation. These both stages of controls on the mechanical properties can be adjusted by changing the morphology of the initial hydrogels and the mechanical stretching ratios. These results will provide a new perspective for the design and manufacture advanced materials with tailored mechanical properties and functions.

“…Patterned coatings of CNCs were used to accomplish highresolution inkjet printing (Figure 15b) on a hydrophobic polystyrene (PS) surface. 183 Uniaxially stretched PDMS was surface-oxidized using plasma to create crack-free periodic wrinkles with a wavelength of ∼850 nm. These wrinkled elastomeric substrates were spin-coated with CNCs and then stamped onto the PS surface using a tiny droplet of water, thereby creating aligned CNCs on the PS surface.…”

Cellulose nanocrystal (CNC) research has addressed increased attention in the bioprocessing community, especially the utility of these materials in different fields, including biomedical and materials applications. In this review, the different preparation methods and properties of CNC materials will be initially briefly discussed. The latter focuses special attention on the alignment of CNCs and its applications. Different methods to induce CNC alignment, including self-assembly, shear-based alignment, magnetic and electric field alignment, spin-coating, dip-coating, etc., are reviewed in detail, followed by the different characterization techniques to quantify the alignments of CNCs. The current and potential applications of aligned CNCs, such as fillers to enhance the mechanical and thermal properties of biocomposites, photonic materials to deal with structural colors and enhancement in optical properties of iridescent films, and reduced wettability for high-resolution printing, are further discussed to provide more insights into this promising research direction. We hope that this review will shine light on CNC alignment and also open the door to different types of applications.
