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 The Challenges of 3D Printing in Construction. High costs. Perhaps the biggest challenge to the widespread adoption of 3D printing technology on construction sites is the high cost of purchasing or Labor shortage. Quality control. Regulations. Show abstract. 3D concrete printing technology (3DCPT) is a growing field of research, in part motivated by attempts to improve current concrete fabricating methods. Compared with traditional 3D printing. 3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [3] with the material being added together (such as plastics, liquids or powder The team won second place and $200,000 in NASA's 3D-Printed Habitat Challenge, Phase 3: Construction Level 3 competition. (3D) construction printing technology has been proposed as a robust The introduction of digital manufacturing techniques, such as 3D printing applied to concrete material, opens up new perspectives on the way in which buildings are designed. Research on this theme is thriving and there is a high rate of innovation related to concrete. At the same time, the first life-size constructions made from printed concrete are emerging from the ground. This book presents This paper considers the possibilities and challenges of particle 3D printing techniques in concrete construction and provides an overview of the current approaches for the production of concrete elements by means of particle-bed 3D printing techniques. A classification is proposed which considers direct component production, the production of 3D printing overview. 3D printing, also called additive manufacturing or additive layer manufacturing, is the process of building a three-dimensional object from scratch, one layer at a time. It generally starts with a digital, 3D model of the component to be manufactured. 3D printing, more formally known as additive manufacturing (AM), has the potential to revolutionise the construction industry, with foreseeable benefits including greater structural efficiency, reduction in material consumption and wastage, streamlining and expedition of the design-build process, enhanced customisation, greater architectural freedom and improved accuracy and safety on-site.
