“…Surpassing traditional methods of clay processing [ 1 ], 3D printing of ceramics started to gain ground in building technology research a few years ago [ 2 , 3 ], yet digital fabrication, allowing for material efficiency [ 4 ] as well as unique aesthetics [ 5 ], primarily focuses on non-sustainable materials such as concrete [ 6 ]. This study aims to address the inquiry of which structural design [ 7 , 8 ], material compositions, and processing techniques [ 9 ] must be devised and what basic material properties [ 10 ] must be acquired to enhance the utilization of 3D printed clay in architectural designs. Building upon research on fiber reinforcement of clay [ 11 ], interest has recently emerged in the possible industrial applications of fibrous reinforcement in the extrusion of 3D printing viscous materials, which is further discussed in this section.…”

This research resulted in the development of a method that can be used for filament-reinforced 3D printing of clay. Currently, clay-based elements are mixed with randomly dispersed fibrous materials in order to increase their tensile strength. The advantages of taking this new approach to create filament-reinforced prints are the increased bridging ability while printing, the increased tensile strength of the dried elements, and the achievement of non-catastrophic failure behavior. The research methodology used involves the following steps: (1) evaluating properties of various filament materials with respect to multiple criteria, (2) designing a filament guiding nozzle for co-extrusion, and (3) conducting a comprehensive testing phase for the composite material. This phase involves comparisons of bridging ability, tensile strength evaluations for un-reinforced clay prints and filament-reinforced prints, as well as the successful production of an architectural brick prototype. (4) Finally, the gathered results are subjected to thorough analysis. Compared to conventional 3D printing of clay, the developed method enables a substantial increase in bridging distance during printing by a factor of 460%. This capability facilitates the design of objects characterized by reduced solidity and the attainment of a more open, lightweight, and net-like structure. Further, results show that the average tensile strength of the reinforced sample in a dry state exhibited an enhancement of approximately 15%. The combination of clay’s ability to resist compression and the filament’s capacity to withstand tension has led to the development of a structural concept in this composite material akin to that of reinforced concrete. This suggests its potential application within the construction industry. Producing the prototype presented in this research would not have been possible with existing 3D printing methods of clay.

The emergence of additive manufacturing (AM) technology for ceramic clay materials has greatly impacted the traditional pottery manufacturing industry. However, there are still limitations in post-processing and structural design for ceramic clay materials in the current field. To address these challenges, in this study, we first used orthogonal experiments to investigate the impact of the heating rate during debinding, the final sintering point, and the insulation time at the sintering point on the performance of the fabricated parts. It was further concluded that the optimal debinding sintering strategy consisted of a debinding heating rate of 0.5 °C/min, a final sintering point of 1300 °C, and a sintering point insulation time of 3 h. Under these conditions, the compressive strength of the specimens reached a maximum of 38.75 ± 4.57 MPa. Herein, we accomplished the printing of two different structures based on liquid deposition molding (LDM) technology. Through comparative analysis of the experimental results, the research solved the buckling phenomenon of flexural specimens and concluded that the octet structure exhibited superior performance. Additionally, we successfully prepared various pottery specimens, further demonstrating this study's application prospects.

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.
