Additive manufacturing (AM) with concrete, also known as concrete 3D printing, is one of the most interesting approaches for disrupting the construction industry and is currently subject to numerous research activities worldwide. AM has great potential to decrease labour costs and increase the material efficiency and geometric complexity of non-standardised building components. Although prior
Similarly, many reviews on 3D printing for construction have been filtered out based on the selection criteria for a sustainability assessment defined above. Careful selection has been performed to include the articles with significant output, to reduce the duplication of results. 3. 3D printing technology for concrete construction: an overview
The global 3D printing construction market was valued at USD 3 million in 2019 and is projected to reach USD 1,575 million by 2024, growing at a cagr 245.9% from 2019 to 2024. The market is growing due to the high demand from the building and infrastructure sectors.
challenges of 3D printing concrete usi ng horizontal extrusion . based technology [26]. When compared to traditional construction methods, 3D printing has enormous potential,
3D printing is an emerging technology that revolutionizes the traditional construction industry. Although it has gained wide attention, implementing the state of the art of 3D printing in construction has remained limited. Since the technology has been developing very fast and many innovations have been made public by nonacademic sources, excluding them would inevitably result in an incomplete
The main benefits of 3D printing in construction include constructability and sustainability benefits. The challenges are categorized into seven groups. The main challenges, found through the
Courtesy of Barry Wark. 3D printing holds vast potential due to its ease of large-quantity manufacturing, its flexibility in terms of material exploration, and its ability to materialize all kinds Additive manufacturing is a fabrication technology that is rapidly revolutionizing the manufacturing and construction sectors. In this paper, a review of various prototyping technologies for printing cementitious materials and selected 3D printing techniques are presented in detail. Benchmark examples are provided to compare three well-known printing techniques; inkjet printing (binder jetting Lessons learnt for metal 3D printing in construction from additive manufacturing using other materials and in other industries are also presented.
