Wishes from the post’s start for a pleasant & restful weekend.
Current scientific literature review sorted by:
A. Published papers:
- “Digital fabrication of eco-friendly ultra-high performance fiber-reinforced concrete” (link), Authors: Arun R. Arunothayan, Behzad Nematollahi, Ravi Ranade, Kamal H. Khayat, Jay G. Sanjayan
- Selected quote/point of interest: “The rheological flow curves of the G-UHPFRC mixtures were non-linear and followed the Hershel-Buckley model. When OPC was partially replaced by SCMs, the yield stress and viscosity were reduced, and the structural build-up rate was lower. Plastic collapses were observed in S0F60 and S30F30 mixtures when a relatively high print speed was employed (80 mm/s). Nevertheless, all mixtures performed sufficiently well when the print speed was 30 mm/s.“
- “Design of novel nozzles for higher interlayer strength of 3D printed cement paste” (link), Authors: Lewei He, Jolyn Ze Mei Tan, Wai Tuck Chow, Hua Li, Jiahui Pan
- Selected quote/point of interest: “The present nozzle optimization also extends to another supplementary paste formula with higher water-cement ratio equal to about 0.23. It is found that the “Kidney” shape achieves the interlayer strength of 2.25 MPa and becomes the optimized outlet design subject to this paste formula, and the “Cir4″ nozzle becomes superior to the “Cir3″ nozzle due to smaller notch depth that is printed. Moreover, the notch depth by the nozzles with the side trowel is further reduced by the higher water-cement ratio of paste, such that the produced interlayer strength is 3.88 MPa, comparable to that generated with the treatment by removing the interlayer notch.“

- Selected quote/point of interest: “Establishing standardized testing procedures for less engineered materials, such as local soil mixtures, would allow for more accurate simulation of truly low embodied carbon materials for construction scale printing.”
- “Modeling the robotics implementation barriers for construction projects in developing countries” (link), Authors: Ayodeji Emmanuel Oke, Ahmed Farouk Kineber, Ibraheem Albukhari, Adeyemi James Dada
- Selected quote/point of interest: “The findings obtained from this study showed that construction professionals exhibited a considerable level of knowledge regarding the adoption of robotics. However, the practical application of robotics in the construction industry was still deficient.”
- “Additive Manufacturing of Sustainable Construction Materials and Form-finding Structures: A Review on Recent Progresses” (link), Authors: Junli Liu, Vuong Nguyen-Van, Biranchi Panda, Kate Fox, Anton du Plessis, Phuong Tran

- “Dimensional Stability of 3D Printed Objects Made from Plastic Waste Using FDM: Potential Construction Applications” (link), Authors: Essam Zaneldin, Waleed Ahmed, Aya Mansour, Amged El Hassan
- Selected quote/point of interest: “The study also concluded that 3D printed material from plastic waste is considered a feasible alternative for several traditional construction elements, such as lightweight concrete hollow blocks, ultra-lightweight concrete hollow blocks, and lightweight concrete bricks, since they are less expensive and have higher compressive strength. The cost per square meter of 3D printed objects is around 41% less than that of the traditional lightweight concrete bricks with a higher compressive strength.“
- “Mechanical evaluations of bioinspired TPMS cellular cementitious structures manufactured by 3D printing formwork” (link), Author: Vuong Nguyen-Van
- Selected quote/point of interest: “This study indicates that the mechanical performance of the TPMS (Primitive and Gyroid) and lattice blocks from the experiment show great agreement with that predicted by the FE analysis.“
- “Effect of accelerated curing and layer deformations on structural failure during extrusion-based 3D printing” (link), Author: A.S.J.Suiker
- Selected quote/point of interest: “Recent experimental research indicates that the buildability of fresh concrete used in extrusion-based 3D printing processes can be significantly enhanced by chemically accelerating the curing process. In the present contribution the effect of accelerated curing on failure by plastic collapse and elastic buckling during 3D concrete printing is explored by incorporating a power-law curing function in the parametric 3D printing model.“
- “A Compact ESPI System for Measuring 3D Displacements” (link), Authors: F. Zanini Broetto, G. S. Schajer

- Selected quote/point of interest: “SHCCs have high potential as materials for 3D building construction. However, most of the previous studies have been conducted based on ordinary SHCC materials, such as ECC, ultra-high-ductility concrete with normal compressive strength of 38.8 MPa, and high-strength FRCCs. Therefore, further research on the development of 3D-printable high-performance SHCCs with over 55 MPa compressive strength and 4% strain capacity is required.”
- “A Multi(two)-Nozzle Cable-Driven Parallel Robot For 3D Printing Building Construction: Path Optimization and Vibration Analysis” (link), Authors: Sy Nguyen-Van, Kwan-Woong Gwak
- Selected quote/point of interest: “To investigate the vibration of the two-nozzle CDPR, its natural frequencies were computed by using the finite element method and its results were verified with a comparison with the commercial software results. Through natural frequency analysis, it was found that the higher stiffness or the higher natural frequencies could be achieved by increasing the minimum cable tension constraint used in the tension distribution optimization algorithm. It is also revealed that the natural frequency goes up as the printing head moves up towards the top center of the workspace.”

- Selected quote/point of interest: “Further developments should be made to consider the variability in mix composition and correlated material curing properties. The diversification in 3D concrete printing technologies (e.g., building rates, time gap, pressure during extrusion, nozzle characteristics) has to be considered in future research: the fabrication of full-scale 3D concrete printed objects, equipping setup with optic measurement tools to improve the accuracy of the results, should provide data useful to validate the employment of the Burgers’ model and the early-age creep quantification.“
