Introduction


With good cause, 3D printing technology has become a popular buzzword in recent years. Since its inception as a means of creating prototypes for new products, 3D printing has become a major player in a range of industries. Even while 3D printing technology has clearly shown its value in the fields of medicine, aerospace, and tool-making since its birth, there is one more area where it could break out: construction. Construction could be reshaped by 3D printing, which is already capable of producing walls and processing cement.


There has been a significant rise over time in the construction industry's use of additive manufacturing. Architects and construction companies are increasingly using concrete 3D printers. Using 3D printing technology, the construction sector is now producing houses, wind turbines, fireplaces, walls, stairwells, and other architectural features using 3D concrete printing.


Concrete 3D printing is becoming more and more popular as a result of the advantages of on-site assembly, reduced time and cost, and improved quality.


Construction sites around the world are being transformed by 3D printed concrete. Contractors face difficulties completing projects because of labor shortages and supply chain disruptions as the construction industry attempts to recover from the COVID-19 outbreak. Today, more than ever, the housing industry urgently needs innovative ideas to reduce costs and make up for lost time due to declining inventory.



The Benefits of 3D Printing in Construction


Speed

Three-dimensional printing has previously demonstrated that a house or other structure can be constructed from the ground up in just a few days. Conventional construction might take months or even years to complete a business building, making this a substantially speedier option.


Waste reduction

It is possible that 3D printing can assist reduce building waste, but this is not a panacea. A big part of this is due to the fact that 3D printing is an additive manufacturing technique that only uses as much material as is necessary to create the structure being printed. Prefabrication and lean construction, both of which reduce waste during construction, raise the prospect of an entirely waste-free structure.


Design freedom

The design flexibility that 3D printing provides is one of its most appealing features. Architects can produce designs that are impossible or too expensive or time-consuming for other construction methods. An increase in commercial construction innovation and inventiveness is possible because of this.


Reduce human error

Using 3D printing on the jobsite will undoubtedly reduce worker injuries and fatalities, as construction would be more programmable and automated.

The Challenges of 3D Printing in Construction


High costs

Because 3D printing technology is so expensive and difficult to transport to building sites, it may be a significant barrier to its widespread use on construction sites. The upfront cost of a 3D printer does not include the cost of materials or maintenance. For the time being, many building experts find it difficult to balance the costs of 3D printing with the potential advantages of the technology.


A scarcity of Labor

Construction is increasing, which means there is a significant demand for qualified labor. All that's missing is a sufficient number. Even with the labor shortage, 3D printing still necessitates a more specialized skill set, which necessitates a smaller pool of potential employees. In a time when qualified professionals are already scarce in the construction industry, obtaining them for 3D printing projects could prove all the more difficult.


Management of quality

Construction can already be slowed by the weather, but 3D printing could amplify the effects of nature. The weather, climatic circumstances, and more might make 3D printing in commercial building a bust rather than a boom. Quality control is already a challenge in construction. Without continual monitoring and oversight by real people, 3D printing quality could turn into a costly disaster.


Regulations

3D printing regulation is an issue that you might not have considered right away as a downside. The building industry has yet to see the full impact of 3D printing regulations, which have been making headlines recently. The downside is that using printers instead of humans for some construction tasks may carry some risk.


This element of 3D printing in construction is now fraught with ambiguity. It's unlikely that 3D printing will have a significant impact on the building industry unless laws and regulations are properly defined.

Future Ahead


Despite the immense promise of 3D printing concrete, it's important to remember that concrete technology as a whole is still in its infancy. The majority of concrete-processing 3D printers are currently under development and aren't ready for mass production. When it comes to building everything from foundations to walls and individual cinder blocks and bridges with additive manufacturing, the possibilities are nearly endless.


Many people believe that a concrete 3D printer is capable of producing a full building, although the walls and foundations are typically built using additive manufacturing processes alone. Contrary to popular belief, however, concrete 3D printing has had a profound effect on the construction business. The recent decade has seen an increase in the number of companies that specialize in the production of concrete. Concrete 3D printers are now being used in an increasing number of countries for the construction of new dwellings.


Numerous new goods have emerged as a result of recent developments in concrete 3D printing technology. Homelessness and environmental preservation are only some of the issues that will benefit immensely from these new technologies.


Here are some examples of 3D printers available in the Market:

CyBe Robot Crawler (mobile 3D printer)


Our CyBe RC is a mobile 3D concrete printer and can be used in multiple locations. Thanks to its portability, this printer is ideal for construction companies and precast factories. The ABB robotic arm is attached on a movable crawler with rubber tracks that make it easy to maneuver the printer regardless of the terrain. The hydraulic feet stabilize the machine while it prints and are extendable, increasing the total printable height of projects.
