Environmental Assessment of ۳D Printed Concrete: Potentials and Challenges, Perspectives, and Opportunities (۲۰۱۳-۲۰۲۳)

۳D Printed Concrete (۳DPC), or additive manufacturing in construction (AMC), is rapidly transforming the construction industry. By offering enhanced automation, faster construction processes, and reduced labor costs, ۳DPC minimizes material waste and enables intricate architectural designs that are not feasible with traditional methods. A comprehensive review spanning ۲۰۱۳–۲۰۲۳ confirms its viability, particularly in remote or challenging environments where conventional construction faces limitations. This technology eliminates traditional formwork, granting unprecedented design flexibility and enabling the creation of complex geometric shapes. The review highlights recent advancements in ۳DPC while acknowledging challenges hindering widespread adoption, including high initial costs, the need for rigorous pre-fabrication structural modeling, and complex regulatory approvals. Conducting cost-benefit analyses is critical for broader industry acceptance. The study emphasizes ۳DPC’s sustainability potential, particularly in reducing environmental impacts. Recognizing the ecological drawbacks of Portland cement, ۳DPC offers a pathway to reduce cement consumption and mitigate the construction industry’s carbon footprint. Strategies to optimize energy and environmental performance include exploring alternative cementitious materials (e.g., geopolymers, recycled aggregates) and refining printing processes to minimize waste. Furthermore, the research examines ۳DPC’s socio-economic implications, such as job creation in advanced manufacturing and localized production benefits. Despite challenges like regulatory complexity and upfront investment, ۳DPC represents a promising avenue for a more sustainable, efficient, and innovative future in construction.
