“…Compared with other printing methods, it adopts synchronous concrete pouring, and the installation of the steel cage does not affect the printing process, which greatly enriches the shape of the building. The columns printed by Anton et al [32] are also similar cases.…”

This paper aims to present an overview and explore components or structures suitable for 3D printed concrete. Most traditional structural forms are not well suitable for 3D printed concrete. To be more specific, it cannot fully consider the characteristics and advantages of 3D printing such as individualization and digitalization. Several 3D-printing-specific structure forms (including hollow form, tree form, arch form, and structure-functional form) are classified and the relevant successful cases are demonstrated. Moreover, the application potential of 3D printed concrete structures is illustrated and the limitations as well as the solutions for the application of 3D printed concrete in practical projects are also summarized. Based on the classification of different reinforcement materials, several reinforcement methods are intensively discussed for 3D printed concrete including steel bars, fibers and other reinforcement materials. The comparison of economic and environmental benefits between 3D concrete printing technology and traditional construction method is discussed respectively. Finally, the expected evolution of 3D printed structures is put forward and recommended.

“…4 Additive manufacturing (AM) shifts the paradigm from mass-production to mass-customization in construction. The AM uses materials characterized by isotropic (concrete, [5][6][7] unreinforced plastics, 8 and metals 9,10 ) or anisotropic (fiberreinforced polymers [FRPs] with thermoplastic 11,12 or thermoset matrices 13 ) material properties. These applications profit from material science and industrial robotics advances, adapting their AM methods to construction-specific needs.…”

Digitization and automation are essential tools to increase productivity and close significant added-value deficits in the building industry. Additive manufacturing (AM) is a process that promises to impact all aspects of building construction profoundly. Of special interest in AM is an in-depth understanding of material systems based on their isotropic or anisotropic properties. The presented research focuses on fiber-reinforced polymers, with anisotropic mechanical properties ideally suited for AM applications that include tailored structural reinforcement. This article presents a cyber-physical manufacturing process that enhances existing robotic coreless Filament Winding (FW) methods for glass and carbon fiber-reinforced polymers. Our main contribution is the complete characterization of a feedback-based, sensor-informed application for process monitoring and fabrication data acquisition and analysis. The proposed AM method is verified through the fabrication of a large-scale demonstrator. The main finding is that implementing AM in construction through cyber-physical robotic coreless FW leads to more autonomous prefabrication processes and unlocks upscaling potential. Overall, we conclude that material-system-aware communication and control are essential for the efficient automation and design of fiber-reinforced polymers in future construction.

Architectural Evaluation of 3D-Printed Buildings

2021

3D-printed constructions express the capacity of automated technologies to elaborate buildings through additive manufacturing. These constructions require an architectural design according to their manufacturing conditions. This research reviews buildings that have been executed with these technologies in order to determine architectural characteristics. From an Internet search, a register was compiled of 112 cases of 3D-printed constructions around the globe. They include some 10,000 m2 of built surface area and were mainly erected in the last five years. The review shows that cases were built by approximately thirty executors, mostly entrepreneurs’ companies who have made different buildings as single-family dwellings constructed with gantries or robotic arms, either on-site or in factories. Most of the components printed are walls, with single or double filaments with interior voids. In some cases, they integrate reinforcements and openings. The geometry of the 3D-printed constructions varies between orthogonal layouts that replicate existing buildings and spherical shapes that reflect printing capabilities. Many of the cases are a combination of these characteristics, mixing a technological adaptation to existing architecture and new operative conditions. This review reveals the emerging development of this construction system with the progressive consolidation of some architectural attributes.
