3D printing is one of the most significant technological developments and innovations of the twenty-first century. Its worldwide market value reached $190 million (USD) in 2021 and is predicted to rise to $680 million (USD) by 2030. 

The elements primarily influencing this expansion include the increased environmental worries about the sector’s waste, the possibility of customization and architectural flexibility utilizing this technology, and the quick fabrication of models and prototypes. 

How does 3D printing in construction work?

Much of the information required to make this technology operate comes from the design phase of the building. Because the industry already has expertise with computer-aided manufacturing and BIM (Building Information Modeling) is flourishing in the construction sector, integrating 3D printing technology is less complicated. A 3D printer gets information about what it needs to produce from a CAD or BIM application, and machines begin to overlay material levels based on the instructions. 

This may be accomplished using various materials, the most typical of which is a combination of concrete, geopolymers, sand, & fiber. 

The advancement of 3D printing over the last decade has been so positive that its worth in the construction business is predicted to reach USD $ 1,034,096.7 thousand by 2028. Between 2021 and 2028, its compound annual growth rate will have increased by 91.5%.

The Advantages of 3D Printing in Construction

Time reduction

Traditional building methods can take many months to finish a job, with major projects often taking 20% longer than projected and costing up to 80% more than the initial budget. However, 3D printing provides time savings of up to 70%, and a project may be finished in hours or days, depending on its size. As a result, contractors may work on more projects, increasing their source of revenue.

More cost-effective and long-lasting

3D printing enables the exact application of material to raise a structure, resulting in up to 60% less waste wasted on construction. Similarly, there will be no excess in the procurement of supplies, assuming cost savings in both the purchase and subsequent storage.

Companies will witness exponential growth in the benefits of this technology by lowering time and costs, which is also very useful in areas where there is a demand for projects but a manpower scarcity. Companies may save up to 80% on labor expenses by automating the building of structures using 3D printers. 

Design adaptability

Last-minute design modifications will no longer be a problem, nor will they cause the building process to be delayed. 3D printing allows you to adjust the work until right before the structure is printed, without all of the problems that these modifications imply.

Safety

One of the most significant advantages that 3D printing has brought to construction is improved employee health and safety. Workers may execute their duties more simply and prevent accidents on the job by learning how to operate efficiently with printers.

Opportunities and challenges for 3D printing in construction

Although the benefits of 3D printing in construction will continue to grow as more firms invest in this technology, attaining larger market adoption of this approach remains a hurdle.

• ​Although 3D printing is more cost-effective when creating, the requisite gear is still quite expensive to purchase and run, and major corporations do not place substantial bets on it.
• More qualified personnel are needed in the sector to manage the technology underlying 3D printing, including those educated to build computer models, run equipment, and offer necessary maintenance.
• More laws and legislation for 3D printing in construction are required to provide clear guidelines on its use and the benefits of implementing it in new building sites. 

Making a genuine difference

Construction and improved infrastructure are in high demand, particularly in major cities. Only 3% of the population lived in cities in 1800; by 1900, the overall population residing in cities had climbed to 15%. Today, 55% of mankind lives in cities, and the World Economic Forum projects that by 2050, two-thirds of the population will reside in major cities.

On a worldwide basis, various government initiatives are being developed to stimulate the deployment of 3D printing. Several cities are competing to win this race, and Dubai is one of them. By 2030, 25% of structures must be created using 3D printing technology.
This beam of 3-D printing technology in construction is not very far away from India, & will reach us very soon to be used on a regular basis. 

Till then, Let’s Build Great Things Together!
