“…In addition, most responsive materials only respond to one type of external stimulus. For tissue engineering applications, printed scaffolds need to adapt to complicated microenvironments of within the human body [134,138] . Therefore, the future of 4D printing requires a stronger focus on microscale controllability over the shape, orientation, or biocompatibility of printed structures.…”

“…They are also valuable model systems for stimuli-responsive smart materials, also known as 4D printing. 4D printing involves materials that are responsive to external stimuli such as electricity, light, ions, temperature, and water, such that the preprinted 3D configuration changes over time [92,[134][135][136][137][138] . In general, shape memory polymers (SMPs) are popularly used for the 4D printing which have permanent shape by a cross-linked polymer network, and can be deformed into a temporary shape via reversible interactions between the networks.…”

Three-dimensional (3D) printing of hydrogels is now an attractive area of research due to its capability to fabricate intricate, complex and highly customizable scaffold structures that can support cell adhesion and promote cell infiltration for tissue engineering. However, pure hydrogels alone lack the necessary mechanical stability and are too easily degraded to be used as printing ink. To overcome this problem, significant progress has been made in the 3D printing of hydrogel composites with improved mechanical performance and biofunctionality. Herein, we provide a brief overview of existing hydrogel composite 3D printing techniques including laser based-3D printing, nozzle based-3D printing, and inkjet printer based-3D printing systems. Based on the type of additives, we will discuss four main hydrogel composite systems in this review: polymer-or hydrogel-hydrogel composites, particle-reinforced hydrogel composites, fiber-reinforced hydrogel composites, and anisotropic filler-reinforced hydrogel composites. Additionally, several emerging potential applications of hydrogel composites in the field of tissue engineering and their accompanying challenges are discussed in parallel.

Tissue regeneration of damaged tissues or complete reconstruction of the organs is the major concern in the human health-care-systems. The role of scaffold, cell, and growth factors decide the final fate of engineered tissues similar to native tissues depending on how they are formulated, arranged and fabricated. In the last decade, 3D printing technique has attracted a great attention to print scaffolds quickly, efficiently, and mass production of fabricated scaffolds with reproducibility as compared to conventional techniques. Further, based on this concept, 3D bioprinting followed by 4D bioprinting have emerged by precise positioning of biomaterials, cells, and biochemical with spatial control in making 3D bio-construct. In this mini-review, the overview of the basic principles of emerged bioprinting techniques, applications, limitations and future perspectives in tissue engineering field are precisely reviewed.

“…It is always promoted as a major form of innovation in many industries, but in fact, research on the topic to date extends for almost 4 decades [1]. The technology application with the construction Industry is attracting field specialist interest day after day for the last few years, aiming to develop a giant scale 3D printer which could print the whole or a part of construction buildings, theoretically in any form or design [2].…”

Abstract. The 3D printing technology is the engine key of the third industrial revolution, after introduction of the automation in the eighteenth century and the concept of mass production in early of twentieth century. 3D printing technology now offers the magic solution to balance both the benefits, and overcome the major associated problem with the previous concept which was the need of repetition. The 3D printing technology has two main critical success factors: the printing machine and the printing material (ink). This paper focusses on cementitious-based materials and the ability to utilize the technology in the construction industry. The research took a qualitative approach based on previous literature reviews as well as in-house research results carried out by the authors' employer Research and Development Center. The paper summarizes the approach towards to an appropriate mix design which can achieve the requirement of the printing process, and overcome the current constraints which are hindering the wide application of 3D print in construction industry. The authors believe that the research topic and result will have great impact on pushing the construction industry forward towards achieving the UAE Government's strategy and target to achieve twenty-five percent (25%) of the buildings in Dubai by the year of 2030 relying on the 3D printing methodology. The research also concluded that even though the technology is adding a great value to the construction industry, it must be remembered that the technology is still in its infancy, and further research is required to achieve even higher strength printing materials that would be workable in multi-story buildings without the need of additional steel reinforcement.
