“…In recent years, polymer nanocomposites have been attracting significant attention not only because of the resulting synergistic properties arising from the nanofiller–polymer matrix combination but also due to their ease of processability via additive manufacturing (AM). Popularly known as 3D printing (3DP), AM, due to its rapidity, accuracy, cost-effectiveness, flexibility, and automation, − has revolutionarily transformed high-performance polymers and polymer nanocomposites to a multitude of multifunctional products with improved mechanical, thermal, and electrical attributes. Such property enhancements are credited to the inclusion of low concentration of rigid and high-aspect-ratio nanofillers such as graphene oxide (GO), − carbon nanotubes (CNTs), and nanoclay, to name a few, which have been remarkably effective in reinforcing many conventional polymer feedstocks for 3DP.…”

Additive manufacturing, or simply 3D printing (3DP), where objects are built through layer-wise material deposition, has gained significant academic and industrial attention as a result of the development of advanced and functional materials requiring rapid, customized, and flexible solutions. In the context of green manufacturing, diversifying environmentally and economically sustainable material portfolios is an essential endeavor for the success of 3DP technology that uses widely available, highly valuable, and renewable materials. In this study, we used stereolithography (SLA) for processing methacrylate-based photocurable resins containing crab shell-derived chitin nanowhiskers (CNWs), which are surface-functionalized by reactive acrylate groups. Results from full spectral, thermal, structural, and topological analyses corroborate not only the surface functionalization of CNWs but also indicate the presence of these photocurable CNW (pCNW) fillers in the 3D-printed nanocomposites. Owing to the strong interfacial bond induced by the physical and chemical crosslinking between the pCNW and methacrylate (MA) polymer matrix, the internally formulated nanocomposites displayed enhanced thermomechanical properties (e.g., storage modulus and glass transition temperature) compared to those of commercially available pure SLA resins. For instance, the inclusion of 0.5 wt % pCNW improved the tensile strength and stiffness to up to 78 and 71%, respectively, without compromising the toughness and ductility of the printed material. Accordingly, this result also evidences the compatibility between the filler and resin materials. Consequently, the formation of a crosslinked network in the nanocomposite structure results in a higher thermal stability and activation energy (i.e., up to ∼79%) for all the hybrid materials than the pristine MA. The high-resolution SLA print features, dimensional accuracy, and enhanced mechanical performance of our microstructure-forming functionalized chitin-based nanocomposites make them promising materials for a wide range of robust and high-performance industrial applications.

“…The principle is to print flowing raw materials onto food substrates, including pizzas, biscuits or bread, through an extrusion nozzle. The requirements are precision, and the printing materials should have a flowing consistency during the printing process (Siacor et al ., 2021). Advantages of inkjet printing include fast printing speed and customisable simple two‐dimensional patterns.…”

Three-dimensional (3D) food printing is a digital food engineering method that has a remarkable application potential in long-term manned spaceflight. Extrusion-based 3D food printing, among the available 3D food printing techniques utilised in the food industry, is one of the most suitable printing methods for manned spaceflight. Extrusion-based 3D food printing could suffice most of the energy and personalised nutritional requirements of astronauts during long-term stay in space by utilising fruits, vegetables, meat products, and nutrients as printing materials. However, 3D food printing in manned spaceflight is still limited by technologies and costs such as printing materials, microgravity, post-processability of food, and engineering transportation under the existing technical conditions. Therefore, this article reviews the 3D food printing and manned spaceflight technologies that are currently available and discusses the challenges involved in 3D food printing in manned spaceflight, thus providing a theoretical basis for future 3D food printing for space missions.

“…In several review papers, we recently reviewed advances in 3D printing methods, materials, including 3D printing for electronics, 10) mechanical testing, 11) high-performance polymer composites, 12) graphene and polyurethane, 13) stereolithographic apparatus (SLA) 3D printing, 14) thermoplastic composites, 15) graphene and SLA, 16) carbon black and selective laser sintering (SLS), 17) silicone elastomers, 18) hydrogels, 19) and viscoelastic materials. 20) In this case, AM could refer to a build-up of layered or multi-layered structures that build on multi-materials or a computer-aided design (CAD) framework design origin. 3D printing in flexible electronics could be a combination of CADbased layer addition and a more serial plug-and-place or pickand-place design to construct a device.…”

There is high interest in the synergism of thin-film and flexible electronics with additive manufacturing (AM). This review primarily focuses on the prospective developments in convergence with flexible electronics manufacturing technologies. Specifically, this paper covers the latest 3D printing and hybrid manufacturing technologies, the utility of specific types of materials, their functionalization and characterization, post-processing and testing strategies toward fabricating robust and application-specific flexible electronics. Besides exploring the advances in this area of research – it also highlights the limitations and gaps that have been observed in the previous years that will challenge and offer opportunities for advancing research and development. Lastly, the future of 3D-printed flexible electronics is discussed in the aspects of customizability, scalability, and its game-changing and state-of-the-art potential for intelligent sensing, instrumentation, and wearables for various medical, engineering, and industrial applications.
