“…The standards governing AM are encapsulated in ISO/ASTM 52900, which provides a comprehensive outline of the fundamental principles and terminologies associated with this domain. Thus, the AEC industry has widely adopted concrete-based additive manufacturing due to the attractive properties of the material, such as its mechanical performance, durability, availability, affordability, and workability, resulting in economic, technical, and scientific advantages [7][8][9], exploring concrete [10][11][12][13], cementitious and geopolymers [14][15][16][17][18][19][20]. Despite these advantages, the environmental footprint of using such materials remains a topic of concern [5,9].…”

Additive manufacturing(AM) has evolved from rapid prototyping to a versatile technology in nano to large-scale fabrication, gaining traction in various sectors such as medicine, aeronautics, and pharmaceuticals. Its recent application in the architecture, engineering, and construction (AEC) industry marks a significant shift, especially in using traditional concrete and steel materials to innovative, sustainable options like clay. The increasing demand for ecofriendly construction materials propels this development. This chapter presents an overview of the latest developments in clay-based AM within the AEC sector. It discusses the challenges and opportunities of this technology, integrating design methods and material approaches. The chapter also examines the critical interplay of geometry, material properties, and process parameters in AM. Aimed at professionals in the field, it offers a comprehensive framework and practical guidelines for engineers, designers, and architects in this dynamic domain.

“…To streamline the fabrication process, industries are looking towards the new upcoming technology of additive manufacturing, which involves adding layer by layer of material for 3D printing of parts [52][53][54]. Different types of materials like plastics [55,56], concrete [57,58], composites [59,60], elastomers [61,62], polymers [63][64][65], metals and alloys [66][67][68][69][70][71][72], and non-metals [73,74] can be used for developing components. Commonly used 3D printing processes for stainless steel alloys, aluminum alloys, titanium alloys, and super alloys are laser powder bed fusion (LPBF) [75][76][77][78][79][80][81][82][83] wire arc direct energy deposition [84][85][86], laser metal deposition [87,88], and additive friction stir deposition [89][90][91] processes.…”

To improve the microstructure and mechanical properties of fundamental materials including aluminum, stainless steel, superalloys, and titanium alloys, traditional manufacturing techniques have for years been utilized in critical sectors including the aerospace and nuclear industries. However, additive manufacturing has become an efficient and effective means for fabricating these materials with superior mechanical attributes, making it easier to develop complex parts with relative ease compared to conventional processes. The waste generated in additive manufacturing processes are usually in the form of powders, while that of conventional processes come in the form of chips. The current study focuses on the features and uses of various typical recycling methods for traditional and additive manufacturing that are presently utilized to recycle material waste from both processes. Additionally, the main factors impacting the microstructural features and density of the chip-unified components are discussed. Moreover, it recommends a novel approach for recycling chips, while improving the process of development, bonding quality of the chips, microstructure, overall mechanical properties, and fostering sustainable and environmentally friendly engineering.

“…Due to the brittleness of salt rock, the production of salt materials with a regular geometric shape is very expensive. Thus, by using salt particles as a mortar component it can be converted into salt building materials by in situ molding, pressing, or 3D printing 8 – 10 , 18 . In the phase of laboratory studies related to the Qatar salt project plan, salt powder, maltodextrin, isopropyl alcohol, water, and microwave processing were used to prepare salt samples 6 , 19 .…”

Sodium chloride (NaCl), commonly known as salt, is a substance that is utilized in a variety of businesses, including the tourism and construction industries. Therefore, the main purpose of this article is to accommodate a salt-based building material called NaCl-binder for tourist and industrial applications. By utilizing salt mortar with varying grain sizes, food-grade corn starch as an exclusive binder agent (without using any non-starch binder), and water under microwave-cured conditions, environmentally friendly hydrophobic hybrid NaCl-binder samples with low bulk density were successfully produced. The fabrication of these samples involved an inventive utilization of small quantities of starch. This study evaluated the impact of microwave exposure time on the strength of salt samples, particle interconnectivity and chemical composition using SEM, XRD, and XRF analyses. The compressive strength of the samples showed a remarkable increase, with a 600% improvement when using 0 to 1% corn starch, and a 137% increment when using 1 to 10% corn starch, indicating a lower rate of increment with higher starch consumption. A key aspect of this research is the significant reduction in starch consumption compared to other corn starch-based materials during the manufacturing process of the incorporated materials, highlighting its novelty and importance.
