Under the trend of digitization and global carbon reductions, clay construction has increasingly attracted attention due to advantages such as an excellent thermal performance, low carbon emissions, and high cost-effectiveness. In this article, an in-depth investigation is conducted into the potential, challenges, and future in the development of digital manufacturing technologies for clay architecture, especially 3D printing, robotic construction, and prefabrication systems. It is revealed through a review that digital clay construction is under rapid development and likely to provide a viable solution to achieving global carbon neutrality, which is conducive to addressing various regional issues. The key findings from this review are as follows. Firstly, as a flexible, precise, and low-carbon industrial solution, 3D printing lays a foundation for the extensive research on materials, equipment, and algorithm optimization. Secondly, the use of machine construction methods such as modern rammed earth technology and drone spraying is effective in improving efficiency and lowering costs. Lastly, the prefabricated building system shows its potential in renewing and developing the rammed earth architecture culture. These findings indicate a massive potential of digital clay construction to support sustainability efforts in the future.

5 kinds of regular polyhedra and 13 kinds of semi-regular polyhedra are taken as the main research objects in this paper to explore the form design method of polyhedral expansion through the rotation of polygon. Firstly, the expandable range of uniform convex polyhedra is defined and divided into two types of expansion. Then three solutions are proposed, namely, discarding polygonal faces, constructing rigid-foldable origami mechanisms and constructing scissor-like elements, so that the prior unexpandable uniform convex polyhedron can be expanded. These methods extend the range of expandable uniform convex polyhedron, and can provide new form design ideas for frontier fields such as movable furniture (toys), movable art installations, 3D kinetic facades and space architecture.

AIGC technology is playing an increasingly crucial role in generative design. At present, many AIGC tools are used to generate images in the architectural design, such as Midjourney, Stable Diffusion. Although the single image generated by AIGC tools might have high quality, it is difficult to maintain the consistency of the ontology when representing the same building from different angles due to the inevitable randomness of the generation process, which means different pictures contradict each other in details. This article discusses the possible solutions of ontology inconsistency problem with the guidance of different AIGC tools, and points out that generating 3D model is the most effective way to solve the problem, but the current generation tools still have various defects. With the contrast of different approaches, the technical path of Sketch-Multiple Pictures-Contradiction Elimination-3D Model is considered to be more appropriate for architectural design process. This path also puts forward technical requirements for the future specialization of current AIGC tools.
