Abstract
The built environment defines humankind’s daily lives, sophistication, efficiency, and effectiveness.
Despite this, its primary industry, construction which transforms the built environment into a reality
and an operation remains in need of more efficient, innovative, and sustainable strategies, technologies,
and instruments. The incorporation of digital fabrication into 3D printing (3DP) technology offers an
entirely different and expanded freedom of geometry, functionality, materials, savings, efficiency, and
effectiveness. For the inherent potential of 3DP technology, its sustainability assessment and potential
contributions should be explored systematically to shed light on future applications and further innovations. This study presents a systematic review of the sustainability potential, assessments, and
challenges of 3DP concrete for built environment applications. A comprehensive and comparative review
of related literature is performed to identify the current trends and research gaps and recommend
reducing or eliminating the energy and environmental footprints and the socio-economic impact. The
study concludes that, in terms of documented global warming potential (GWP) values, 3DP technology
appears to be a promising alternative to conventional construction and concrete use. A life cycle analysis
(LCA) is recorded that is meant to be widely used as an assessment tool for environmental and energy
assessment in digital fabrication technology, leaving an integrated review, including social and economic
aspects, understudied. The 3DP concrete technology has unlimited potential in terms of material flexibility, savings, labour’s cost, design flexibility, and operation agility. Besides, researchers intend on
introducing unconventional and locally available materials to increase the sustainability of 3DP technology in construction
