“…In the second step, the minimal surfaces can be generated to create the internal geometry of the brick with walls thickness of about 0.8 cm. In particular, six minimal surfaces are investigated by considering some of the most used surfaces in digital manufacturing [32][33][34]: Gyroid [28], Shwarz Primitive [28], Shoen's Batwing [35], Battista-Costa [36,37], Diamond [29], Sherk tower [38].…”

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.

“…The ultraviolet light irradiance parameters play a significant impact in the photopolymerization of resins. The wavelength and intensity of UV light 143 have a significant impact on resin curing. The impact of various laser strengths, halogen lights, and LEDs with a power range of 0.1–2 W on the curing efficiency of the photopolymer resin.…”

“…A low-viscosity resin with a high degree of fluidity reaches the build tray quickly and is suitable for printing high-resolution designs. 143 It is essential to have a low-viscosity resin to be injected into the nozzle for a cost-effective solution. Photosensitive resins with low viscosity are critical for good performance.…”

This article investigates the state-of-the-art of polyjet 3D printing of polymers and multi-material structures, with an emphasis on its applications in a range of industrial domains, including aerospace, architecture, toy fabrication, and medical field. While significant research and development in the field of additively manufactured (AM) multi-material and reinforced composite structures have been carried out during the previous decade, the need of the hour is to utilize a single manufacturing platform which would not only help to govern the composition, shape, and characteristics of multi-material 3D printed objects at the microscopic level but would also help industries to replace the conventional AM manufacturing methods and optimize their mechanical performance. Significant advancements in polyjet 3D printing of fiber-reinforced and functionally graded structures with numerous modifications in material composition are reviewed, which may revolutionize the industrial sector. Numerous polyjet printing parameters such as accuracy, printing speed, photo-curing effect, build orientation, layer thickness, print angles, and post-processing are comprehensively discussed, and best outputs to optimize the mechanical performance and enhance the accuracy of the polyjet 3D printing products are highlighted. FEA (finite element analysis) models and analytical relations for multi-material 3D printed structures are presented to predict and enhance the overall performance of polyjet fabrication. Along with the benefits of polyjet manufacturing, a few of the limitations and challenges of polyjet AM are addressed which would benefit the reader to conduct further research in this field and enhance fabrication quality significantly. Vivid comparisons with other multi-material AM fabrication techniques such as FDM, SLA, and SLS with their brief discussion, merits, and demerits are done.

“…MJ technology is also utilized in the production of lattice geometries to be used in different types of testing instead of selective laser melting (SLM) technology which has been intensively used in lattice specimen production but the cost of which is much higher than for polymer-based parts [ 128 ]. In one study, MJ technology was used to evaluate the compressive behavior of triply periodic minimum surface lattice structures [ 129 ]. To overcome the limitation, the technology was used to produced special honeycomb structures in which a solid side wall of the traditional honeycomb structure can be replaced by a porous side wall, which resulted in improved stiffness and strength [ 130 ].…”

Material jetting (MJ) technology is an additive manufacturing method that selectively cures liquid photopolymer to build functional parts. The use of MJ technology has increased in popularity and been adapted by different industries, ranging from biomedicine and dentistry to manufacturing and aviation, thanks to its advantages in printing parts with high dimensional accuracy and low surface roughness. To better understand the MJ technology, it is essential to address the capabilities, applications and the usage areas of MJ. Additionally, the comparison of MJ with alternative methods and its limitations need to be explained. Moreover, the parameters influencing the dimensional accuracy and mechanical properties of MJ printed parts should be stated. This paper aims to review these critical aspects of MJ manufacturing altogether to provide an overall insight into the state of the art of MJ.
