3D Printing in Construction, Mixture Characteristics, Strength, and Thermal Performance-Review (2023-06)¶

All industries have embraced three dimensions printing, which is shown to offer several advantages. This article examines the use of 3D printing in the construction industry. Concrete is the primary component when using 3D printing in a building; reinforcements are either seldom employed or not used at all. Although having many advantages, this building approach has some drawbacks. The substance utilized to make the printable paste combination is currently being researched because this is a novel technology. To meet the needs of 3D printing, material use, and mixing proportions have considerably different qualities from those of conventional building methods. As a fundamental need, three-dimensional printed concrete(3DPC) demands that an object be printed, buildable, resilient, and consistent. Knowing that 3D printing seldom uses reinforcement to increase strength, durability, or stability is crucial. This article offers a concise overview of all the applications, difficulties, and prospects for 3DPC. The article starts out with defining 3D printing before going on to discuss its prerequisites and challenges. It also examines the fundamentals of 3D printing in concrete, including its background, uses, and advantages. In this article, printing techniques and materials are thoroughly examined, and a material that is optimum for sustainability is suggested.
