A type of additive manufacturing called three-dimensional concrete printing (3DCP) makes it possible to create intricate architectural details straight from digital three-dimensional design using CAD software (3D CAD) models eliminating the requirements of traditional molds or fixtures. This innovative technology is gaining traction due to its efficiency in producing precise prototypes with reduced material waste and minimal human intervention. Its applications range from manufacturing structural components to on-site construction of walls, addressing various design and technical challenges. With a focus on sustainable practices, such as the use of recycled aggregates, ecologically friendly binders, chemical admixtures, and nano-additives to enhance mix designs, this chapter critically examines developments in 3DCP. It also examines current studies on the rheological characteristics needed for efficient printing, highlighting its potential for environmentally beneficial structural and ornamental uses. The chapter ends with a list of research gaps, especially with regard to improving longevity and continued reliability of 3D-printed concrete buildings.

摘要

A type of additive manufacturing called three-dimensional concrete printing (3DCP) makes it possible to create intricate architectural details straight from digital three-dimensional design using CAD software (3D CAD) models eliminating the requirements of traditional molds or fixtures. This innovative technology is gaining traction due to its efficiency in producing precise prototypes with reduced material waste and minimal human intervention. Its applications range from manufacturing structural components to on-site construction of walls, addressing various design and technical challenges. With a focus on sustainable practices, such as the use of recycled aggregates, ecologically friendly binders, chemical admixtures, and nano-additives to enhance mix designs, this chapter critically examines developments in 3DCP. It also examines current studies on the rheological characteristics needed for efficient printing, highlighting its potential for environmentally beneficial structural and ornamental uses. The chapter ends with a list of research gaps, especially with regard to improving longevity and continued reliability of 3D-printed concrete buildings.
