Sustainable Non-Conventional Concrete 3D Printing—A Review

In this review article, system materials for concrete 2D printing have been discussed, along with the various other aspects that are connected to sustainable construction. The article consists of an introduction giving background manufacturing started almost two decades ago, including non-conventional methods building structures. It has seen there stainable in field 3D construction, as conversion construction reduces waste generation. Further cost comparison between conventional and effectiveness printing; is very effective sense it requires precise use machinery material. Full-scale also sector, but only some extent. Some components bridges, even small constructed using ultra-high-performance concrete. Since advantages building, disadvantages printing, such how much costs finding suitable which might increase cost. Polymers used since polymers a long lifespan, may strength final product by reinforcing aggregate. Additionally, technology gives us opportunity together recycled aggregates geopolymers, cement, pose challenges being nowadays. A major concern its impact on labor market. traditional huge amounts man hours required, concerns raised about inclusion technology, affect employment. most work will be done machines, need reduce. These issues attention. Finally, discusses novelty future scope concludes outlining potential developments taking into account sustainability.
