3D printing in construction: The future of Construction
By 3D printing we mean the computer guided sequential layering of materials to create three-dimensional shapes. It is widely used for creating prototypes and for the manufacturing of geometrically complex components.
Now let us look at 3D printing in construction. The first attempt at creating a 3D printed wall was undertaken by Professor Behrokh Khoshnevis of the University of South Carolina in 2004. This innovation has exploded since then. At present it is possible to build a 3D printed house in just 20 hours. Behrokh developed an FDM 3D printer, mounted on a robotic arm that releases layers of concrete.
Now that we know 3D printed construction is possible, now let’s look why it is needed.
• 3D printing concrete saves a lot of time, potentially reducing a 2 week job to just three to four days. Other than that, it also reduces the risk of injury at work.
• In terms of material usage, 3D printing is economical. It comparatively used less material than traditional manufacturing processes.
• 3D printing allows structures to be created more quickly, it is ideal to combat the housing crisis. A handful of companies are shifting towards additive manufacturing as a result.
Construction giants are quickly realizing the potential of 3D technology and their chances to be the future of construction. The 3D printing in construction market is expected to reach $56.4 million in the year 2021 and that too for good reason.
More and more companies are starting up in the sector to create new, innovative projects. 3D concrete printing is developing rapidly and relies on various technologies and materials, thereby offering many benefits to its users. This technology is still in its infancy and has its current limitations.
