3D Printing: The Revolution in Construction Industry in Future

3D printing in building construction is a modern technology in construction. Technology replaces manual construction. So this is the latest technology in any construction field. All the construction work is controlled and managed by the computer. we can create a 3D  construction design in computer software like CAD, Sketchup, Architect 3D, etc then after the applicant in the site by the printing machine. 

In this article, 3D printing is used for new building construction and advantages of others related topics. So let’s get started:

What is 3D printing in construction?

Building components and even whole structures may be created utilizing large-scale 3D printers in the construction industry. With this technique, a digital representation of the building is created using computer-aided design (CAD) software and then sent to a 3D printer. The components are then built up by the printer layer by layer utilizing a range of materials, such as metal, plastic, and concrete.

Construction projects might be completed more quickly and efficiently, with less waste, and with more design freedom thanks to 3D printing.

By reducing the need for employees to do hazardous or labor-intensive jobs, this technology has the potential to save construction costs and enhance safety.

But there are also drawbacks to 3D printing in the building industry, including the need for specific tools and knowledge and the need to make sure that produced parts adhere to safety and building code requirements.

However, the use of 3D printing in the construction sector has the potential to transform the sector and alter how we see the design and construction of buildings.

Advantages of 3D printing in construction

Construction projects are completed more rapidly because it is possible to build complicated components and structures fast and precisely.

Labor expenses will be lower since 3D printing will replace the requirement for experienced personnel to produce complicated designs and details.

Improved accuracy and precision in constructing components, reducing waste and mistakes.

Increased customizability and design freedom, enabling the creation of original and cutting-edge architectural designs.

Increased environmental effects as a result of less waste and the use of recyclable and sustainable resources.

Increased worker safety since 3D printing reduces the need for dangerous jobs to be performed by employees.

Lower shipping and logistics expenses since 3D printing enable component manufacture on-site.

More successful and efficient construction projects are the result of improved communication and collaboration between architects, engineers, and contractors.

increased output since numerous components may be produced simultaneously using 3D printing.

It is a practical alternative for a variety of building projects due to its ability to produce small and large projects at a reasonable cost.

Types of 3D printing 

Different 3D printing technologies are employed in the construction of buildings. Here are a few of the most typical:

Fused Deposition Modeling (FDM)

The most prevalent use of 3D printing in the building industry is this one. In FDM, a thermoplastic material is melted and extruded via a nozzle to form material layers that are subsequently assembled to form a 3D object.

Stereolithography (SLA)

Lasers are used in SLA to transform liquid resin into solid objects. computer-controlled mirror directs the laser to selectively cure the resin layer by layer.

Powder Bed Fusion (PBF)

PBF entails applying layer of powder material and utilizing laser or electron beam to selectively fuse it. Up till the 3D item is finished, the process is repeated.

Binder Jetting (BJ)

In BJ, layer of powder material is covered with liquid binder. To create solid item, the powder particles are bound together with the aid of the binder. Up till the 3D item is finished, the process is repeated.

Concrete 3D printing

In this method, particular concrete mixture is extruded via nozzle to produce layers of concrete that are then built up to produce three-dimensional object.

Each of these 3D printing techniques has benefits and drawbacks of its own. The technology that is employed to create building is dependent on the project’s unique requirements.

Case studies of successful 3D printing projects

The followings are some case studies of successful 3D printing projects in construction:

With the use of a 3D printer that was 20 feet high, 120 feet long, and 40 feet broad, the first 3D-printed office building in the world was built in Dubai in 2016. The project decreased labor expenses by 50% and was finished in 17 days.

A 30-square-meter social housing unit was 3D printed in approximately 54 hours by the French construction firm XtreeE in 2019. The project showed how 3D printing has the ability to decrease waste, speed up building, and produce cheap homes.

A concrete barracks facility was 3D printed by the US military in 2020 in just three days. A massive 3D printer was used to finish the project, which cut the building time by 50% when compared to conventional techniques.

A concrete footbridge in the city of Nijmegen was 3D printed in 2021 by a Dutch business named The Form Foundation. To cut down on the time and labor needed for construction, the bridge was printed in parts, then put together on location.

In just 45 days, a six-story residential complex was built in China using the biggest 3D printer in the world. Construction waste was reduced by 60% as a result of the project’s utilization of a variety of recycled materials.


In recent years, 3D printing technology has completely changed the way that buildings are constructed. Using cutting-edge technology, architects and engineers can now design and create intricate architectural structures that were previously considered to be unachievable using conventional building methods.

Building components and accurate, detailed models may be created with 3D printing and made swiftly and effectively. This technology has given architects and designers new options, enabling them to design structures with features that were previously thought to be too complex or expensive to construct.
