“…(iii) In the third phase, an advanced printing simulation is developed in order to identify the best minimal surfaces configuration and other geometrical parameters suitable for designing and printing the new bricks. The simulations are obtained by linking the bricks parametric model with the Abaqus simulation software [23].…”

“…Such analyses are aimed to identify the most effective minimum surfaces and the number of repetitions of the geometry within the brick. The approach is based on an effective plug-in named VoxelPrint for Grasshopper [23] that can be used to construct simulation files, designed specifically for 3D printing applications for viscous material, such as concrete. Such plugin exploits voxelization of the designed three-dimensional shapes into a set of identical finite elements and it produces ready-to-use input files for simulation in Abaqus.…”

The building construction sector is undergoing one of the most profound transformations towards the digital transition of production. In recent decades, the advent of a novel technology for the 3D printing of clay opened up new sustainable possibilities in construction. Some architectural applications of 3D-printed clay bricks with simple internal configurations are being developed around the world. On the other hand, the full potential of 3D-printed bricks for building production is still unknown. Scientific studies about the design and printability of 3D-printed bricks exploiting complex internal geometries are completely missing in the related literature. This paper explores the new boundaries of 3D-printed clay bricks realized with a sustainable extrusion-based 3D clay printing process by proposing a novel conception, design, and analysis. In particular, the proposed methodological approach includes: (i) conception and design; (ii) parametric modeling; (iii) simulation of printability; and (iv) prototyping. The new design and conception aim to fully exploit the potential of 3D printing to realize complex internal geometry in a 3D-printed brick. To this aim, the research investigates the printability of internal configuration generated by using geometries with well-known remarkable mechanical properties, such as periodic minimal surfaces. In conclusion, the results are validated by a wide prototyping campaign.

In the last few years, scattered experiences of the application of additive manufacturing in the construction of buildings using 3D printing with robots or automated equipment have emerged around the world. These use a variety of procedures and suggest relevant advantages for the construction industry. In order to identify the different processes and features in development in this field and to guide future research and applications, this article presents a review of the literature on the main aspects involved in the use of 3D printing in the construction sector. The review includes state-of-the-art material mixtures, printing technologies, and potential uses, as well as a novel analysis of building strategies, management systems, and benefits stated about this new approach for construction. It reveals progressive experimentation regarding diverse features, with challenges related to the consolidation of procedures and this technology’s readiness to participate in the building market.

“…Sharp edges and selfintersecting print paths create topological problems that impede the simulation. Voxel-based methods offer a simplified approach that create less accurate simulations but are robust against these issues [74]. The multiple forces and parameters involved in the deposition have also been studied with computer fluid simulation (CFD) methods that offer higher accuracy, but their higher computational requirements make them not suitable for full-scale simulations [75,76].…”

Functionally graded materials (FGMs) describe composite materials with a gradual change in properties along one or several axes. A major advantage with this approach is the avoidance of discontinuities between different layers of material. 3D Printing offers the possibility to control the material composition and spatial placement along the printing process to create structures with graded properties. However, there are very few examples of the application of this approach to 3D concrete printing (3DCP). This paper presents a review of the current approaches of and methods to grade the material properties of a 3DCP structure, as well as a review of similar methods used in other 3D printing processes. Finally, the potential applicability of these principles into concrete are presented and discussed.
