The rise of 3D printing in construction

The adoption of 3D printing by the construction industry has paved the way for a wealth of innovations and advancements for the trade, with the global market size of 3D printing construction estimated at $53.9 million as of 2024. By leveraging the evolution of 3D printing within construction, the industry is set to benefit environmentally, economically, and structurally.

In our article below, we explore the impact of 3D printing on construction, and the advantages it has introduced.

What is 3D printing?

3D printing is the process of creating a three-dimensional object from a digital file, by layering a material until the desired object is complete. This innovative and advanced modern technology produces sophisticated shapes and structures that would be difficult or impossible to achieve with traditional manufacturing methods. Digital manufacturing solution, Protolabs Network, informs how the printing method is classed as an additive technology as it does not require additional features to hold materials together, instead the specific layering technique fuses the materials together.

How is 3D printing used in construction?

YardLink shared how gantry-style printers and robotic-arm printers are amongst the most popular forms of 3D printing software being used in construction. These machines are able to produce architectural structures on a large scale, with materials such as concrete, plastic and metals. As technology evolves, the future of 3D construction promises even more advancements, with innovations like drones for inspecting sites and artificial intelligence for optimising designs expected to further enhance the capabilities of 3D printing, making it a foundation of modern construction.

The basis of 3D printing in construction follows:

• Design: Create a digital design of the desired construction
• Print: Program 3D printing software to follow the design, where it will layer your chosen material to create the structure
• Finalise: Add features which require manual installation, such as windows, doors, pipes and wiring, to finish the build

The benefits of 3D printing in construction

3D construction is transforming the way we build, offering a host of benefits and solutions that address many of the challenges faced by the traditional construction industry. From speed and efficiency to sustainability and design innovation, the advantages of 3D construction are setting new standards for the future of construction.

Efficiency

One of the most significant benefits of 3D construction is the rate at which structures can be built. 3D construction is able to streamline processes, such as preparing sites, laying foundations, and assembling frameworks, by using automated machinery to build structures precisely and rapidly. For example, a 3D printer can construct the walls of a new building in just a few days, with KnowHow claiming that a small 3D printed home can be built in less than 24 hours. This improvement in construction timelines allows for projects to be completed quicker, allowing developers to meet tighter deadlines.

Environmentally friendly

Sustainable construction practices are becoming an increasingly high priority in the industry. 3D construction is inherently more sustainable than conventional construction due to its precision and utilisation of the exact amount of material required for each layer, minimising any excess and reducing the overall environmental footprint.

3D printers are able make use of a variety of eco-friendly and recycled materials to enhance the sustainability of the construction process. A scientific journal revealed how this sustainable practice will help to address resource depletion and decrease waste generation, representing great potential for revolutionising the construction industry.

Cost effective

By reducing labour costs, minimising material waste, and accelerating project timelines, 3D construction can lead to substantial cost savings, making projects more financially viable. The automation of the construction process reduces the need for a larger workforce, with the advanced precision meaning fewer costly errors.

3D construction can make affordable housing more accessible by cutting down on construction costs, allowing developers to offer housing at lower prices and address the housing shortages in many areas.

Customisation

The ability to customise and personalise buildings is another significant advantage of 3D construction. Clients are able to work closely with architects to design spaces that meet their specific needs and preferences, achieving a level of customisation which is often difficult through less flexible, traditional construction.

Whether it’s a bespoke home with individualised floor plans or a commercial building with a custom front, 3D printing allows for the use of unique features and elements to create tailored spaces.

Design flexibility and innovation

3D construction opens up new opportunities in construction design, allowing for the creation of complex and intricate plans that would be challenging or impossible to achieve with conventional techniques. Medium shares how the flexibility of 3D printing allows architects to experiment with structures and materials, enhancing the aesthetic appeal of buildings and enabling the construction of more functional and optimised spaces.

Durability

Contrary to some misconceptions, 3D-printed buildings can be incredibly robust and durable. The layer-by-layer construction process allows for precise control over the density and composition of the materials used, resulting in structures that can be tailored to withstand specific environmental conditions and varying loads.

3D construction can incorporate advanced materials such as high-strength concrete and composite materials, which are able to even further enhance the longevity of buildings. The precision in 3D printing ensures that structures are built to exact specifications, reducing the likelihood of defects and increasing overall safety.

Reduce human error

3D construction significantly reduces the potential for human errors by automating much of the building process with a precision which ensures that each layer is placed accurately according to the design specifications, eliminating the inconsistencies and mistakes which can occur with manual labour.

This reduction in human error not only enhances the quality and reliability of the finished structures, but also streamlines the construction process, making it more predictable and efficient. UCEM supports how this helps to reduce delays, as well as the chances of losing money and resources through mistakes.

Increased safety

3D printing can help to mitigate risks on construction sites, such as injuries from heavy machinery and exposure to hazardous materials, by reducing the need for human labour through the use of automated machinery to perform previously manual tasks. The controlled environment in which 3D printing takes place means that safety standards can be more easily maintained, protecting workers and reducing the burden on the industry’s labour force.
