“…Among all AM technologies, direct ink writing (DIW)-an extrusion-based 3D printing technique, has been used for AM of biomaterials using sustainable resources, such as eggshells, seashells, and rice husk biochar. [203][204][205][206] This particular AM technique has been known for its versatility in multiple material fabrication, [231] e.g., for permanent implants made of Ti6Al4V-𝛽-TCP [232] and biodegradable implants made of MgZn-𝛽-TCP [233] and FeMn-akermanite. [234] Although extrusion-based 3D printing of calcium phosphate made from eggshells and seashells and rice husk-derived SiO 2 foams has been successful, further studies and improvements are required to achieve properties that are required for their application as bone implants particularly when the implants are to be used as load-bearing devices.…”

“…Research on AM of agricultural waste precursors (i.e., rice husk), potentially for tissue engineering, has only recently appeared in the literature. [205,206] Extrusion-based AM was employed to fabricate the architected monolithic SiO 2 foam (Figure 7e) with a high total porosity (i.e., ≈89%) and a tailorable pore structure (Figure 7f,g). [206] This lightweight rice husk-derived SiO 2 foam has the potential to be studied as a controlled on-demand drug delivery system for tissue regeneration.…”

The need for sustainable development has never been more urgent, as the world continues to struggle with environmental challenges, such as climate change, pollution, and dwindling natural resources. The use of renewable and recycled waste materials as a source of raw materials for biomaterials and tissue engineering is a promising avenue for sustainable development. Although tissue engineering has rapidly developed, the challenges associated with fulfilling the increasing demand for bone substitutes and implants remain unresolved, particularly as the global population ages. This review provides an overview of waste materials, such as eggshells, seashells, fish residues, and agricultural biomass, that can be transformed into biomaterials for bone tissue engineering. While the development of recycled metals is in its early stages, we highlight the use of probiotics and renewable polymers to improve the biofunctionalities of bone implants. Despite the advances of additive manufacturing (AM), studies on AM waste‐derived bone‐substitutes are limited. It is foreseeable that AM technologies can provide a more sustainable alternative to manufacturing biomaterials and implants. The preliminary results of eggshell and seashell‐derived calcium phosphate and rice husk ash‐derived silica will likely pave the way for more advanced applications of AM waste‐derived biomaterials for sustainably addressing several unmet clinical applications.This article is protected by copyright.

Additive manufacturing (AM) presents a promising opportunity for the innovative design and production of structured catalytic materials. Given the critical role of catalysts in industrial catalytic processes, AM has the potential to contribute to the development of improved catalysts by reducing activation energy and enhancing selectivity. Conventional synthesis methods limit the choice of structural materials and composition for producing monoliths. Additionally, the deposition of catalytic compounds is also restricted by commonly applied techniques that may require prior coverage or treatments to improve adherence or do not achieve a homogenous coat. Moreover, production is limited to monoliths with straight and parallel channels. However, this format drives to laminar regime flow thus restricting the radial mass and heat transfer. Conversely, AM allows the production of a wider variety of compositions and more complex structures that have proven to rise their effectiveness by increasing reagents‐catalyst interaction, making catalytic processes more cost‐effective. Therefore, in this review an outline of the recent progress of AM methods in the development of monolithic catalysts is presented focusing on the requirements, advantages, and disadvantages of each technique, hence providing a practical overview of their novel opportunities to overcome current limitations in catalyst synthesis.

The potential of three‐dimensional (3D) printing technology in the fabrication of advanced polymer composites is becoming increasingly evident. This review discusses the latest research developments and applications of 3D printing in polymer composites. First, it focuses on the optimization of 3D printing technology, that is, by upgrading the equipment or components or adjusting the printing parameters, to make them more adaptable to the processing characteristics of polymer composites and to improve the comprehensive performance of the products. Second, it focuses on the 3D printable novel consumables for polymer composites, which mainly include the new printing filaments, printing inks, photosensitive resins, and printing powders, introducing the unique properties of the new consumables and different ways to apply them to 3D printing. Finally, the applications of 3D printing technology in the preparation of functional polymer composites (such as thermal conductivity, electromagnetic interference shielding, biomedicine, self‐healing, and environmental responsiveness) are explored, with a focus on the distribution of the functional fillers and the influence of the topological shapes on the properties and functional characteristics of the 3D printed products. The aim of this review is to deepen the understanding of the convergence between 3D printing technology and polymer composites and to anticipate future trends and applications.image
