The technology continues to advance, it presents a number of different opportunities to make construction faster, cheaper, and less wasteful.
While its use in the construction industry still has lots of room to grow, 3D printing is already making a significant impact on construction projects all over the world. If you work in construction, chances are you’ll be using some sort of 3D printing technology in the near future, so what makes 3D printing so useful in construction, and what are its applications?
Benefits of 3D Printing Technology in the Construction Industry
3D printing offers a number of benefits that will undoubtedly transform the construction industry for the better. From being able to print structures and individual building components quickly and efficiently to cutting down on construction waste, 3D has the potential to significantly lower construction costs while also making the industry more sustainable and eco-friendly.
3D printing is also incredibly flexible, allowing architects and construction companies to design and construct unique structures that simply wouldn’t be possible to build with more conventional construction methods. All of this, along with enhanced worksite safety and reduced reliance on human labor, makes the 3D printing trends in the building and construction industry impossible to ignore.
Applications of 3D Printing Technology in the Construction Industry
3D printing’s incredible flexibility makes it perfect for a wide variety of different applications on the construction site, and this is just the beginning. As the technology continues to mature, innovative construction businesses will find new ways to harness the power of 3D printing to finish projects more efficiently and effectively than ever before.
Here are just a few of the many ways that the construction industry is already using this promising technology to build better, faster, and more cost-effectively.
Modeling and Prototyping
One of the first ways that 3D printing technology has impacted the construction industry is through its ability to make custom models and prototypes. Every construction project starts with a design, and whether you need to convince apprehensive investors or test the limits of particular building materials, being able to print to-scale models of these designs is incredibly useful in the preliminary stages of any construction project.
3D Concrete Printing
Concrete is by far the most heavily used building material in construction projects all over the world, so the prospect of being able to print concrete structures with a 3D printer is nothing less than industry transforming.
3D concrete printers work just any standard 3D printer by printing individual layers of concrete on top of each other until it forms a complete structure. Many construction companies have already started using 3D concrete printers to construct entire homes, but scaling continues as some building projects are simply too large for a single concrete printer to build.
3D Printing Individual Building Materials and Components
The good news is that current 3D printing technology can overcome the scalability issues mentioned above. While one individual concrete printer may not be able to construct entire structures above a certain size, their ability to print individual building components that workers can assemble on the job site often makes up for this.
Through this method, construction companies can print large building components offsite and then transport them to the construction site, where workers can assemble the final product. This again speeds up the construction process, reducing labor costs and budgets.
Powder Binding
Powder binding is an advanced type of 3D printing technology that provides even more benefits than standard concrete printing. While there are different ways to do this, the main difference is that powder-binding prints using a powder and binding agent to create structures instead of concrete.
This method is even cheaper and more efficient than standard 3D printing as unused powder can be recycled and reused, but that’s not all. This method also provides even more flexibility as it can print using various building materials, including metal, ceramic, sand, polymers, and mineral composites, but there are some drawbacks.
The results of powder binding are quite porous, which limits the current applications of this 3D printing technology in the construction industry to printing smaller, mostly metal and ceramic building materials.
Wire Arc Additive Manufacturing
Metal is another type of building material that is in high demand on every construction site, and while powder binding can print some metals, wire arc additive manufacturing takes the process to the next level.
Instead of using powder and metal binding agents, wire arc additive manufacturing prints lines of metal layer by layer, making it much more structurally sound and ideal for construction projects. It also has the ability to print complex and highly detailed designs and can be used for everything from printing to welding different building materials together.
