Is Design

In order to use 3D printing technology as a sanction, it is necessary to optimize topology, component unification, and reduce weight need for advanced manufacturing design. In the case of metal 3D printing, it is necessary to manage deformation and defects in the process cause of using laser, and support generation and design optimization must be accompanied for efficiency. Currently, design progresses through simulation before actual production in AM field. This chapter explores design in additive manufacturing.

Working Practices

The development of high-end, distributed, advanced manufacturing over the last decade has been a by-product of a push to foster new workforce capabilities, while building a market for industrial additive manufacturing (3D printing) machines. This trend has been complemented by a growing democratization in access to commercial platforms via the internet, and the ease of communication it allows between consumers and producers. New ways of distributed working in manufacturing are on the rise while mass production facilities in the Western world are in decline. As automation increasingly excludes the worker from assembly line production, the tools to regain control over manufacturing and commercial interaction are becoming more readily available. As a result, new working practices are emerging. This chapter discusses networked 3D printing build farms and their potential to reshape the future of work for distributed manufacturing. It highlights changes in infrastructure priorities and education for a digitally enabled maker society from an Australian perspective.

Shape memory polymers (SMPs) are stimuli-responsive materials, which are able to retain an imposed, temporary shape and recover the initial, permanent shape through an external stimulus like heat. In this work, a novel manufacturing method is introduced for thermoresponsive quick response (QR) code carriers, which originally were developed as anticounterfeiting technology. Motivated by the fact that earlier manufacturing processes were sometimes too time-consuming for production, filaments of a polyester urethane (PEU) with and without dye were extruded and processed into QR code carriers using fused filament fabrication (FFF). Once programmed, the distinct shape memory properties enabled a heating-initiated switching from non-decodable to machine-readable QR codes. The results demonstrate that FFF constitutes a promising additive manufacturing technology to create complex, filigree structures with adjustable horizontal and vertical print resolution and, thus, an excellent basis to realize further technically demanding application concepts for shape memory polymers.

This manuscript presents a novel polyMOC network that can reversibly switch between three distinct states of mechanical and chemical properties, significantly extending the boundaries of stimuli-responsive materials. This triple switching phenomenon is enabled by a unique photoreduction mechanism that leverages Cu<sub>24</sub>L<sub>24</sub> self-assembled metal-organic cages (MOCs) embedded in an elastic polymer gel. The properties of each material state can be used in a cooperative fashion to achieve advanced functions such as network toughening, metallic patterning, and additive manufacturing<br>

Sophisticated Version

Over the last few decades, advanced manufacturing and additive printing technologies have made incredible inroads into the fields of engineering, transportation, and healthcare. Among additive manufacturing technologies, 3D printing is gradually emerging as a powerful technique owing to a combination of attractive features, such as fast prototyping, fabrication of complex designs/structures, minimization of waste generation, and easy mass customization. Of late, 4D printing has also been initiated, which is the sophisticated version of the 3D printing. It has an extra advantageous feature: retaining shape memory and being able to provide instructions to the printed parts on how to move or adapt under some environmental conditions, such as, water, wind, light, temperature, or other environmental stimuli. This advanced printing utilizes the response of smart manufactured materials, which offer the capability of changing shapes postproduction over application of any forms of energy. The potential application of 4D printing in the biomedical field is huge. Here, the technology could be applied to tissue engineering, medicine, and configuration of smart biomedical devices. Various characteristics of next generation additive printings, namely 3D and 4D printings, and their use in enhancing the manufacturing domain, their development, and some of the applications have been discussed. Special materials with piezoelectric properties and shape-changing characteristics have also been discussed in comparison with conventional material options for additive printing.

External Stimuli

Smart polymers are materials that respond to small external stimuli. These are also referred as stimuli responsive materials or intelligent materials. Smart polymers that can exhibit stimuli-sensitive properties are becoming important in many commercial applications. These polymers can change shape, strength and pore size based on external factors such as temperature, pH and stress. The stimuli include salt, UV irradiation, temperature, pH, magnetic or electric field, ionic factors etc. Smart polymers are very promising applicants in drug delivery, tissue engineering, cell culture, gene carriers, textile engineering, oil recovery, radioactive wastage and protein purification. The study is focused on the entire features of smart polymers and their most recent and relevant applications. Water soluble polymers with tunable lower critical solution temperature (LCST) are of increasing interest for biological applications such as cell patterning, smart drug release, DNA sequencing etc.

Mechanical Stretching

Direct translation of mechanical force into changes in chemical behavior on a molecular level has important implication not only for the fundamental understanding of mechanochemical processes, but also for the development of new stimuli-responsive materials. In particular, detection of mechanical stress in polymers via non-destructive methods is important in order to prevent material failure and to study the mechanical properties of soft matter. Herein, we report that highly sensitive changes in photoluminescence intensity can be observed in response to the mechanical stretching of cross-linked polymer films when using stable, (pyridinophane)Cu-based dynamic mechanophores. Upon stretching, the luminescence intensity increases in a fast and reversible manner even at small strain (< 50%) and applied stress (< 0.1 MPa) values. Such sensitivity is unprecedented when compared to previously reported systems based on organic mechanophores. The system also allows for the detection of weak mechanical stress by spectroscopic measurements or by direct visual methods.<br>
