In the 1980s, designers used emerging 3D printing technology as an affordable way to assess and adjust prototypes. Today, advanced 3D printing capabilities are revolutionizing the construction industry.
In this article, we will look at 3D printing in construction, its benefits and limitations, and why we can expect to see continued demand on traditional builders’ supply materials and construction methods.
Applications for 3D Printing in Construction
The use of 3D printing in construction has expanded into full-scale applications, including the following:
- Building models: 3D-printed prototypes continue to play a major role in the construction process. As an essential design tool, architects and designers deploy rapid prototyping to produce and study complex building concepts. It is now a critical step in the design process, allowing architects and clients to refine designs while improved collaboration between builders and designers helps reduce the risk of errors and costly change orders.
- Creating building components: 3D printers can generate full-scale building components such as walls, panels, and columns that are ideal for modular building methods.
- Complex designs: 3D printing also provides a cost-effective way to create more intriguing designs. Architects and interior designers can create modern spaces, introducing innovative shapes that are difficult to achieve using traditional methods and materials alone.
- Complete structures: 3D printers can be used on an even larger scale, creating “contour crafted” buildings. Robotic arms and extruders are programmed to translate blueprints into full-scale structures, working from the ground up. The printers apply concrete materials layer by layer to create complete building shells.
- Producing sustainable materials: 3D printers facilitate the use of sustainable materials, extruding bio-based polymers or recycled concrete in the contour-crafting process.
The Benefits of 3D Printing in Construction
There are many advantages to 3D printing in construction, including the following:
Improved Timelines
3D printing allows builders to construct complete building shells without the need for traditional construction methods. This saves significant time, allowing builders to more effectively meet the growing demand for housing. It also expedites emergency building capabilities following natural disasters, fires, etc.
Reduced Construction Costs
3D printing eliminates time-consuming steps that require specialty equipment and large teams of construction workers. This reduces labour costs, focusing on skilled trades to complete finishing stages such as electrical, plumbing, window installation, etc.
Overall, projects become more cost-effective with savings in material expenses, as 3D printers help reduce costly material waste. On-site printers also decrease transportation costs, allowing builders to produce various structures and components on demand.
Innovative Designs
3D printers introduce limitless design options, allowing architects and interior designers to create unique focal points and aesthetics not achievable using traditional materials and methods. This is creating a new era of architectural designers who push the envelope using intricate design methods.
Overcoming Construction Labour Shortages
Although demand will continue for skilled trades, the current shortages of construction labour can be overcome with the assistance of 3D printers. The ability to automate time-consuming, labour-intensive processes will refocus construction opportunities toward positions using brain power.
Reducing Construction Hazards
Deaths and injuries were somewhat reduced when the construction industry shifted towards a safety culture that improved practices and equipment. However, in 2022, 183 construction workers died on the job, with falls being the number one cause of death.
Unfortunately, risks are on the rise as the industry faces pressure to produce housing faster, leading to shortcuts that disrupt new safety protocols. 3D printing can help reduce hazards at construction sites, taking on tasks performed at dangerous heights and making it safer to work in confined spaces.
Providing Viable Building Materials
In areas of the world where builders’ supply materials such as wood and steel are not readily available, 3D printing produces concrete structures on-site. This provides hope for affordable housing and improved infrastructure in areas where materials and skilled labour are limited.
The Limitations of 3D Printing in Construction
While 3D printing is making advancements in construction applications, the following limitations continue to place demand on traditional builders’ supply materials and construction methods.
Material Quality and Performance
Contour-crafted materials provide a quick way to create building shells affordably, but time will tell how building codes and standards impact 3D-printed structures. These new materials have yet to demonstrate their structural integrity and will have to stand up to regulatory approval, material standards, and certifications.
Scalability and Cost
While there’s mention of cost-savings using 3D printing methods, mass production of the technology has yet to be seen. Manufacturing these large-scale printers en masse is necessary for the technology to become affordable.
Adding to the issue of affordability and scalability is the challenge of continuously evolving technology. These advancements apply to both the materials produced by 3D printers and the printer technology itself. Ongoing improvements can disrupt mass production and the widespread use of this technology in the construction industry.
Material Limitations
Although 3D printing can introduce innovative designs, the materials available to bring those designs to life are limited. As a result, a selection of smart and traditional builders’ supply materials will continue to play a critical role in construction.
The Future of 3D Printing in Construction
Eventually, 3D printers will become a staple at construction sites, allowing builders to produce a growing selection of materials on demand, including advancements in interior walls, insulation, and structural supports.
Robotics will help automate manual tasks, increasing tandem work between manual labourers and 3D printers. Housing shortages and disaster responses can also be tackled more effectively with speedier construction processes both in the design and building stages.
Improved collaboration among architects, designers, engineers, contractors, construction companies, and clients will affect all aspects of construction, reducing risks, controlling costs, and helping to eliminate errors.
However, widespread adoption of 3D construction will also require standardization processes and regulatory approval before contour-crafted buildings become the industry norm.
While we can expect to see 3D printing continue to revolutionize the construction industry, traditional builders’ supply materials and construction methods will continue to play a key role in the building process.
