Developing sustainable 3D printable concrete materials using olivine sand for carbon sequestration Suvash Chandra Paul, Junghyun Lee, Yi Wei Daniel Tay, Issam T. Amr, Bandar A. Fadhel, Ming Jen Tan Discover Sustainability, 2026 3D concrete printing (3DCP) is an emerging and innovative technology that creates concrete structures layer by layer from a digital model. This method has significant potential to enhance productivity and safety in construction. 3D printing facilitates the use of innovative design principles while promoting the smart and efficient utilization of materials and resources. It allows for customization and the creation of intricate geometries without incurring additional costs. Consequently, adopting 3D printing technology in construction can yield substantial economic and environmental benefits. This study explores the use of olivine sand as a replacement for natural river sand in the production of 3D printable material. Olivine is believed to absorb CO 2 directly from the atmosphere, which could enhance concrete properties and protect environment from carbon emission. Natural sand was replaced with olivine sand in varying percentages of 0%, 25%, 50%, 75%, and 100%, and their effects on 3D printed structures were investigated. The 3D printed samples underwent tests for mechanical strength, rheology, and thermogravimetric analysis (TGA). The results indicated that replacing natural sand with olivine did not adversely affect strength; rather, it produced positive outcomes at certain replacement levels, with the primary goal of capturing CO 2 from the atmosphere.
In-process filament repair in 3D concrete printing with instance segmentation Tan Kai Noel Quah, Zhi Xin Liu, Yi Wei Daniel Tay, Ming Yang Li, Ming Jen Tan, Teck Neng Wong, King Ho Holden Li Virtual and Physical Prototyping, 2025 3D Concrete Printing (3DCP) stands as an automated method using robotics to construct concrete structures layer by layer, offering time efficiency, cost savings, and improved safety. Despite its practical relevance, on-site operators are still necessary to identify printing issues. While research focuses primarily on material optimisation, lesser attention is given to processing, software, and building integration aspects. This study delves into the gaps and correction behaviour of 3DCP cementitious materials, employing simulation tools and computer vision. Using varied nozzle speeds (60, 30, and 20 mm/s), repairs were attempted above simulated gaps on the base layer. Observations revealed a slump-like behaviour in filament gaps, increased layer width for 33.3% and 50% speeds, and the necessity for smaller repair adaptability. Optimal repair speed for filament tears fell between 33.3% and 50% of the nozzle travel speed. Assessing real-time in-process scanning and repair for a closed-loop system proved promising, though hardware limitations introduced unforeseen noise. Future work suggestions encompass improved simulated models, nozzle travel speed optimisation, enhanced inference models for higher layers, and nozzle adaptations for smaller repairs.
Unlocking the sustainable potential of 3D concrete printing with large aggregates and steam–CO2 curing Suvash Chandra Paul, Junghyun Lee, Yi Wei Daniel Tay, Sean Gip Lim, Jihye Jhun, Bandar A. Fadhel, Issam T. Amr, Ming Jen Tan Materials Science in Additive Manufacturing, 2025 Three-dimensional concrete printing (3DCP) has emerged as a promising innovation in the construction industry, significantly reducing its reliance on intensive labor while minimizing material waste. Despite its benefits, a major limitation of current 3DCP practices is the high reliance on cement as the primary binder, which often exceeds 60% of the total solid content. This high cement usage contributes significantly to CO2 emissions, raising sustainability concerns. In this study, a 3D-printable concrete mix incorporating large aggregates (up to 10 mm) was developed, replacing over 7% of fine aggregate and reducing cement content to approximately 29% by weight. The effects of CO2 gas and a steam–CO2 mixture on the mechanical performance and CO2 uptake of the printed concrete were assessed. Thermogravimetric analysis was used to quantify CO2 sequestration over time. Compared to control samples without gas treatment, those exposed to the steam–CO2 mixture showed enhanced buildability, improved compressive and flexural strength, and greater CO2 uptake. The results suggest that surface spraying of the steam–CO2 mixture during the 3D printing process offers a viable and scalable approach to improving both the structural performance and environmental footprint of printed concrete elements.
Potential of carbon dioxide spraying on the properties of 3D concrete printed structures Yi Wei Daniel Tay, Sean Gip Lim, Bandar A. Fadhel, Issam T. Amr, Rami A. Bamagain, Ali S. Al-Hunaidy, Suvash Chandra Paul, Ming Jen Tan Carbon Capture Science and Technology, 2024 Achieving net carbon neutrality is a global goal toward mitigating climate change presumed consequences. The building and construction sector, responsible for approximately 40 % of greenhouse gas emissions, requires innovative zero-carbon technologies. This paper investigates the synergistic potential of combining 3D concrete printing (3DCP) and carbon capture and sequestration (CCS) to advance net carbon neutrality in construction. By implementing different CO2 spraying regimes, this study demonstrates improved carbon dioxide (CO2) uptake and the crystallinity of precipitated calcium carbonate (CaCO3). The findings indicate that the method's effectiveness heavily relies on appropriate printing parameters and curing conditions. Chamber-cured samples exhibit the highest CO2 uptake but the lowest mechanical strength, while ambient-cured samples show the opposite trend. It is also important to note that the duration of CO2 exposure in this study was relatively short, resulting in limitations in both CO2 uptake and strength gain. Nevertheless, this study highlights the potential of synergistically combining 3DCP and CCS technologies for net carbon neutrality, emphasizing the critical role of the construction sector in achieving global emission reduction targets.
Carbon capture and sequestration with in-situ CO2 and steam integrated 3D concrete printing Sean Gip Lim, Yi Wei Daniel Tay, Suvash Chandra Paul, Junghyun Lee, Issam T. Amr, Bandar A. Fadhel, Aqil Jamal, Ahmad O. Al-Khowaiter, Ming Jen Tan Carbon Capture Science and Technology, 2024 Profound reliance of the building and construction sector on cement exacerbates its immense carbon footprint, accounting for a substantial portion of worldwide emissions. In this paper, we investigate the possibilities of in-situ carbon capture and sequestration to eliminate spatial constraints from a chamber confined curing solution via CO 2 and steam integrated 3D concrete printing. The presented technology involves a two-step extrusion-based system that sequesters captured CO 2 directly into concrete prior deposition at the nozzle printhead, so as to achieve artificially accelerated carbonation reactions with enhancement of mechanical properties. Accordingly, samples subjected to in-situ CO 2 and steam integration showed increases of up to 50.0 % 3D printability, 36.8 % compressive strength, and 45.3 % flexural strength compared to control at its respective curing conditions. The results of said approach demonstrated 38.2 % increase in bulk carbon uptake compared to accelerated carbonation confined curing methods, offering an alternative pathway towards decarbonized construction with 3DCP.
Sustainable Support Material for Overhang Printing in 3D Concrete Printing Technology Guan Heng Andrew Ting, Yi Wei Daniel Tay, Tan Kai Noel Quah, Ming Jen Tan, Teck Neng Wong Applied Sciences Switzerland, 2024 The advantage of 3DCP technologies is the ability to fabricate free-form structures. However, printing openings in concrete structures are limited by the presence of overhanging sections. While various 3D printing and additive manufacturing technologies have established methods for handling overhangs with temporary supports, many existing techniques for 3D concrete printing still rely on wooden planks and corbelling, which restrict the design flexibility and slope angles. The objective of this study is to develop a removable and sustainable support material with high printability performance. This support material serves as temporary support for overhang sections in 3D-printed structures and can be removed once the primary concrete has hardened sufficiently. This study observed that increasing the recycled glass content in the mixture raises both the dynamic and static yield stresses, with only mixtures containing up to 60% recycled glass remaining pumpable. Optimization of the mixture design aimed to balance high flowability and buildability, and the results indicated that a mixture with 60% recycled glass content is optimal. The effectiveness of the optimized support material was validated through the successful printing of a structure featuring a free-form opening and overhang section.
