“…The need of advanced materials is divided into two different categories that are the high-tech materials for data transfer within the smart manufacturing components (i.e., machines, data transfer units, processors, semiconductors, etc.) and common materials for everyday applications (i.e., plastics/polymers, glasses, ceramics, metals, and their combination) [69]. In the former category, sensors consist of the largest portion of the applications that require a combination of insulators, conductors, and actuators, which change phase depending on the incoming signals [70].…”

Additive manufacturing (AM) or three-dimensional (3D) printing has introduced a novel production method in design, manufacturing, and distribution to end-users. This technology has provided great freedom in design for creating complex components, highly customizable products, and efficient waste minimization. The last industrial revolution, namely industry 4.0, employs the integration of smart manufacturing systems and developed information technologies. Accordingly, AM plays a principal role in industry 4.0 thanks to numerous benefits, such as time and material saving, rapid prototyping, high efficiency, and decentralized production methods. This review paper is to organize a comprehensive study on AM technology and present the latest achievements and industrial applications. Besides that, this paper investigates the sustainability dimensions of the AM process and the added values in economic, social, and environment sections. Finally, the paper concludes by pointing out the future trend of AM in technology, applications, and materials aspects that have the potential to come up with new ideas for the future of AM explorations.

“…This minimum contact angle that occurred in the perpendicular direction of 3D printing further implied a dominant orientation of capillary flow. Hence, it suggests a useful rule of 3D printing design applicable to microfluidic flow spontaneously delivered through microchannels generated by the FDM method in the future [6, 36, 37].…”

Additive manufacturing (AM) of spongy (cancellous) microstructures in the development and application of piezoelectric sprayers was investigated. The structures featuring microfluidic channels were made of solid polylactic acid (PLA) by fused deposition modelling (FDM) designed with a width of 35 mm, a depth of 25 mm, a height of 56 mm, and a cross-layer thickness of 2 mm. In total nine network structures were altered with the line widths (W d) from 300 to 500 μm and the line spacing (S d) from 250 to 400 μm. Then, one piezoelectric plate and another micronozzle array were assembled with the structures as a microactuator. The piezoelectric actuator had a resonance frequency of 107.8 ± 1 kHz, in which it generated microsprays of 3 ml water with a typical volumetric rate of ∼1.1 ml/min. On the basis of FDM with PLA, the works' dimensional error analysis showed that the minimum AM errors (<5%) between the design and actual dimensions occurred with the W d of 350 μm and the S d of 300-350 μm. In addition, they experimentally discovered anisotropic wettability and different roughness of the PLA layered surfaces, largely concerning the microfluidic performance of the network structures of the piezoelectric sprayer.

4D printing is an emerging field in additive manufacturing of time responsive programmable materials. The combination of 3D printing technologies with materials that can transform and possess shape memory and self-healing capabilities means the potential to manufacture dynamic structures readily for a myriad of applications. The benefits of using multifunctional materials in 4D printing create opportunities for solutions in demanding environments including outer space, and extreme weather conditions where human intervention is not possible. The current progress of 4D Printable smart materials and their stimuli-responsive capabilities are overviewed in this paper, including the discussion of shapememory materials, metamaterials, and self-healing materials and their responses to thermal, pH, moisture, light, magnetic and electrical exposures. Potential applications of such systems have been explored to include advancements in health monitoring, electrical devices, deployable structures, soft robotics and tuneable metamaterials.
