The construction industry's role in reducing its considerable carbon footprint is pivotal. Recent advancements in 3D concrete printing (3DCP) and carbon sequestration technologies for cement-based materials (CBM) have presented immense potential for sustainable construction operations. Nevertheless, decarbonization of the construction sector remains an ongoing challenge. Although the integration of carbon sequestration technologies with 3DCP provides an avenue for further progress, there exist numerous concerns that need to be thoroughly evaluated and addressed. This review article discusses the state-of-the-art techniques of 3DCP for a sustainable built environment, the fundamentals of carbon utilization and sequestration with CBM, as well as the possibility of integrating both technologies to facilitate net-zero emissions by 2050.
