“…[ 45 ] The peaks in the wavelength range between 989 and 1239 cm −1 is due to the distortions of CH and CO groups in polysaccharides affiliated to aromatic rings. [ 46 ] The presence of glycosidic connections affiliated to cellulose is confirmed by the absorbance peak at 726 cm −1 . [ 47 ] From the FTIR spectrum, the minimal damage caused to APALF powder during the extrusion and 3D printing process for manufacturing of APALF/PLA composite is ensured.…”

The aim of this study is to develop a completely sustainable, biodegradable, eco-friendly and green composite material for packaging of food and medical products by an additive manufacturing technique such as 3D printing. This report presents the mechanical, crystalline, chemical bonding and thermal characteristics of a novel pineapple leaf fiber (PALF) reinforcing polylactic acid (PLA) green composite manufactured by 3D printing technique. Both powdered raw and alkali-treated PALFs were respectively mixed with PLA and extruded as filaments for 3D printing into composite test specimens. The characterization study reveals that the 3D printed composite with 3 wt% (alkalitreated) PALF reinforcement exhibited maximum tensile and flexural characteristics. The density of the 3D printed composite specimens increased with increase in wt% of PALF. On the other hand, the 3D printed composite specimens blended with raw PALF showed enhanced elongation at break compared to alkali-treated PALF reinforced composite specimens. The microstructural images of the 3D printed composite specimens confirms the existence of impurities, voids and fiber degradation phenomenon. The Fourier transform infrared spectra revealed the chemical bonding nature of the 3D printed composite specimens. The X-Ray diffraction was used to calculate the crystalline size and crystallinity index. Thermogravimetric analysis reveals that the 3D printed composite specimen possessed adequate thermal stability for use in packaging applications.

“…It has been reported that aligned structures could be obtained with the assistance of shear force from the nozzle. [ 15 , 17 , 18 ] To evaluate the alignment effect, the small‐angle X‐ray scattering (SAXS) results of the HAp‐monodispersed RBCs inks squeezed through the nozzle channel were characterized, as shown in Figure 3 . Schematic of the nozzle geometry used for the SAXS experiments is shown in Figure 3a .…”

“…Direct ink writing (DIW) 3D printing technology based on extrusion can be used for the programmable assembly of 3D architectures. [ 14 ] Controlled particle orientation is typically achieved by shear‐induced arrangement in the printing process, including alumina platelets and nanowires, [ 15 ] carbon fibers, [ 16 ] silicon carbide whiskers, [ 17 ] and cellulose nanocrystals. [ 18 ] However, it is challenging to develop viscoelastic inks that can be easily extruded, and yet form a self‐supporting feature after exiting the nozzle.…”

Mimicking the multi-scale highly ordered hydroxyapatite (HAp) nanocrystal structure of the natural tooth enamel remains a great challenge. Herein, a bottom-up step-by-step strategy is developed using extrusion-based 3D printing technology to achieve a high-precision dental crown with multi-scale highly ordered HAp structure. In this study, hybrid resin-based composites (RBCs) with "supergravity +" HAp nanorods can be printed smoothly via direct ink writing (DIW) 3D printing, induced by shear force through a custom-built nozzle with a gradually shrinking channel. The theoretical simulation results of finite element method are consistent with the experimental results. The HAp nanorods are first highly oriented along a programmable printing direction in a single printed fiber, then arranged in a layer by adjusting the printing path, and finally 3D printed into a highly ordered and complex crown structure. The printed samples with criss-crossed layers by interrupting crack propagation exhibit a flexural strength of 134.1 ± 3.9 MPa and a compressive strength of 361.6 ± 8.9 MPa, which are superior to the corresponding values of traditional molding counterparts. The HAp-monodispersed RBCs are successfully used to print strong and bioactive dental crowns with a printing accuracy of 95%. This new approach can help provide customized components for the clinical restoration of teeth.

“…The simple mechanism for nanoparticle alignment in DIW also attracted much attention for 2D nanoparticles, such as MXene platelets, boron nitride (BN) nanosheets, and graphene layers. − Shahbazian-Yassar et al developed a DIW-based, poly(ethylene oxide) (PEO) silane-treated hexagonal boron nitride (s-hBN) composite polymer electrolyte . Through shear-induced alignment, s-hBN showed higher alignment in the printed direction, as shown by the IR images .…”

The field of additive manufacturing (AM) has witnessed spectacular growth in the past 4 decades because of its revolutionary processing mechanism in combining bottom-up and top-down approaches. Many have speculated that it will challenge traditional fabrication methods as the fourth industrial revolution. Among the subfields of threedimensional (3D) printing, extrusion-based direct ink writing (DIW) is known for its vast material choices, high design flexibility, and acceptable cost efficiency to print many urgently demanded material systems, such as hydrogels or aerogels, nanoparticle suspensions, composite mixtures, liquid crystals, and liquid metals. Furthermore, the DIW's ability to construct complex architectures or hierarchies also contributes to broader applications across different fields, including intelligent robotics, energy generation and storage devices, biomedical implants, and sustainability systems. This review provides a comprehensive summary of recent advances in DIW development, focusing on engineered patterns at different scales, namely, nanoparticle alignment, one-dimensional (1D) fiber microstructure manipulation, and macroscale two-dimensional (2D)/3D spatial patterning. It highlights the hierarchies from nanoscale particle orientations to macroscale long-range-ordered structures. Finally, technical barriers and significant challenges prohibiting DIW for broader applications or impeding fundamental research to industrial commercialization are discussed.
