“…3D printing, also known as additive manufacturing or rapid prototyping, is a process for constructing 3D physical objects from digital models through the successive layer-by-layer deposition of materials such as metals, ceramics, polymers and/or living cells [19]. The two most common technologies used in 3D printing are stereolithography (SLA), where the solid part is produced from liquid or ink by polymerization; and fused deposition modeling (FDM), where a continuous filament of thermoplastic is used to form hardened continuous layers [20].…”

“…A schematic of 3D printing for nanocellulose-based hydrogels is shown in Figure 2. Printability of the ink through the micro nozzle is an important factor that governs the quality of the fabricated structures, and is characterized by the ink’s rheological properties to flow and maintain its printed shape, preventing single filament deformation [19]. Moreover, biocompatible inks that can crosslink at body temperature in a short time, with a low photoinitiator concentration and/or requiring low intensity UV light are generally considered attractive materials for 3D bioprinting [24,25].…”

Nanocellulosic materials, such as cellulose nanocrystals, cellulose nanofibers, and bacterial nanocellulose, that display high surface area, mechanical strength, biodegradability, and tunable surface chemistry have attracted great attention over the last decade for biomedical applications. Simultaneously, 3D printing is revolutionizing the field of biomedical engineering, which enables the fast and on-demand printing of customizable scaffolds, tissues, and organs. Nanocellulosic materials hold tremendous potential for 3D bioprinting due to their printability, their shear thinning behavior, their ability to live cell support and owing to their excellent biocompatibility. The amalgamation of nanocellulose-based feedstocks and 3D bioprinting is therefore of critical interest for the development of advanced functional 3D hydrogels. In this context, this review briefly discusses the most recent key developments and challenges in 3D bioprinting nanocellulose-based hydrogel constructs that have been successfully tested for mammalian cell viability and used in tissue engineering applications.

“…The goal of this initiative is for the refugees themselves to harbor the intellectual capital and resources to utilize these skills to address issues rising from conflict areas such as Syria. The key is the open-source nature of the technology associated with 3D printing including mobile computer-aided designs (CAD) which are crowdsourced blueprints for an array of products including medical devices and tools (Bhatia and Ramadurai 2017). The simultaneous deployment of human capital in conjunction with open-source technology such as 3D printing creates a paradigm shift whereby no longer are humanitarian operators conventional agents such as aid workers, but, rather, the conflict victims and refugees themselves.…”
