3D Concrete Printing - The Concept of the New Era

Published On: November 2022

Personalization is possible thanks to various technologies, including 3D concrete printing market technology. The 3D substantial printing market can create intricate shapes, making it a viable long-term option. New computational technologies and 3D printers have the potential to change how we build our environment, according to recent studies. This technique makes it possible to fabricate and test various devices needed to evaluate the construction quickly and affordably.

Although this new technology has a lot of advantages and benefits, it still has some limitations, which causes us some concern. Although 3D printing in the construction industry has shown promise in several other sectors, it is still in its early stages. The effect of 3D printing on the construction industry shouldn't be understated because it can shorten the duration of projects and cut expenses associated with materials and labor.

Restrictions to 3D Concrete Printing 

Before becoming widely used, concrete printing and other AM technologies still needed to overcome several challenges. This entails exact material placement and distribution, management, and observation of the material's phase transition from the fresh to the hardened state.

Additionally, concrete stacking may produce "cold joints," essentially weak connections between layers, and reduce structural strength. Important factors to consider include the product's surface polish, the usage of steel or fiber reinforcement, and more. Additionally, established guidelines, standards, and testing protocols to vouch for the secure and long-term application of concrete printing as a construction technique have yet to be developed. The following critical properties of concrete must be enhanced to successfully 3D print concrete structures:

• 
  

  Extrudability

  
  


• 
  

  Flowability

  
  


• 
  

  Buildability

  
  


• 
  

  Open hours 

  
  


• 
  

  Layer-to-layer interactions

  
  

Future of 3D Concrete Printing in Construction  

Although the 3D concrete printing market has been around since the early 1980s (Stereolithography, Fusion Deposition Modelling), it has been slowly gaining popularity. There are numerous potential directions for the technology, but it will become more cost-effective in several industries, opening the door to additional research and mass customization in architecture. Even though 3D concrete printing is still in its early stages across many industries, it seems to be progressing due to its potential advantages. Others believe that 3D printing will revolutionize the construction industry and will primarily be utilized to make building components and panels in factories or on-site.

3D Concrete Printing Market Analysis 

Due to construction restrictions imposed by the government to alter the spread of COVID-19, the residential segment of the end-user market was most adversely affected. The 3D concrete printing market has significantly improved in Asia-Pacific and other developing nations. In nations like India, there is a greater demand for housing than there is supply. In developed areas, there has also been an increase in housing demand. Overall, the industry is expected to get a boom after lifting restrictions imposed due to COVID, and it has a great future ahead.

Impact of COVID-19 on the Sector

The 3D printing industry overcame the pandemic by initially adjusting and becoming a formidable force in the battle against COVID-19. In response to the global increase in cases and the subsequent surge in demand for hospitals and isolation rooms, concrete 3D printing technology was used to construct isolation cottages rapidly. Due to rapid industrialization and urbanization, several key factors are propelling the global market, including increased demand for customized construction, eco-friendly factors, cutting-edge technology, and 3D concrete printing market price.

Conclusion

People's perceptions of concrete as a standalone 3D printable material have altered because of the rapid growth of 3D printing technology. Construction is one of the industries with the highest labor costs, low productivity, and minimal use of technology. Like robots and other automation technology, 3D concrete printing is becoming more popular in the building sector.

The research claims that 3D concrete printing significantly lowers the labor force required for construction and can reduce labor costs by up to 80%. As a result, it is anticipated that 3D concrete printing will address the labor shortage issue, particularly in countries where construction is heavily dependent on migrant labor. On the other hand, countries, where the construction industry relies heavily on their workforce may suffer if jobs are lost because of 3D concrete printing. The 3D concrete printing market size is likely to expand during the ongoing forecast period to reach a market sum of USD 978.5 million by 2030 while growing at a global CAGR of 55.60%.
