3d printing technology is transforming every industry with its innovative applications. Over time, additive manufacturing has become advanced, capable, and dependable as more companies are now integrating it with their existing manufacturing processes.
This technology is streamlining the complex manufacturing processes and helping companies take care of the environment. If we specifically talk about the construction industry, 3d printing offers a wide range of eco-friendly applications that save both the environment and operational costs.
With exponential industrialization and skyscraping development happening globally, the problem of excessive CO2 emissions due to massive concrete production is increasing. Concrete is the second most used material on the planet after water, and the emission of harmful gases is growing each year.
Problem with concrete
Concrete material is not only environmentally unfriendly but also requires additional support to remain intact. This material is excellent in compression, but it’s inferior in bending, torsion, and tension. Due to this shortcoming, engineers need to use additional steel rebar. Manufacturing these rebars is a very complex and time-intensive task.
With the fast-paced development, it’s nearly impossible to find concrete alternatives or cut down the production to protect the environment. But, it’s possible to introduce an efficient option to steel rebars that are cost-effective and eco-friendly.
A researchers’ team at UC Berkeley is closely working towards producing a durable $rebar replacement$ using 3d printing technology. As per the research, additive manufacturing can help engineers reduce environmental damage by using high-strength plastic internal structures instead of steel rebars.
3d printed plastic rebar replacement
With additive manufacturing, engineers can build a more robust and durable geometric structure that can replace the need for steel rebar. The inner geometry is made in a lattice structure to give more tensile strength to the design. These plastic rebar replacements are made up of high-strength materials like ABS and PLA polymers.
How does it work?
Using advanced $3d printing$ technology, engineers first spring lattice-shaped geometrical structures to replace the steel rebar. Once the design is ready, it is kept in the pouring mould, and engineers pour ultra-high-performance concrete (UHPC) over it. Like the traditional rebar, it covers the entire structure.
The UHCP covers the entire lattice structure, and the final product looks like the traditional block or slab of concrete. The most significant advantage of this process is that companies can save hours of labour work from laying the rebar and tying them together to form a structure.
With this advancement, engineers can use premade CAD files and print as many rebars as they need without contributing to the excessive carbon emission. Compared to steel, polymers are more environmentally friendly, and hence they cause negligible damage.
As the rebar structure is available in a CAD file, engineers can modify the geometry to improve its overall strength without designing it from the beginning. In the upcoming time, we will see the use of more eco-friendly polymers that are potentially carbon-negative.
In traditional concrete blocks or slabs, the fibre distribution is uneven, which negatively impacts the structure’s overall strength. However, using additive manufacturing, designers can pay closer attention to the design and ensure higher fibre distribution for reducing cracks in the concrete body.
Advantages of 3D printed plastic rebar
When $3d print plastic$ replaces the traditional steel rebars, it brings numerous advantages to manufacturers and helps them build better quality products. With additive manufacturing, manufacturers can leverage several benefits, including:
Lower carbon emission
The most significant advantage of leveraging additive manufacturing in the construction domain is lower carbon emission. As this problem is becoming more severe, this approach towards redefining the rebars can help to bring a positive change.
In the upcoming time, we will see the use of carbon-neutral 3d printed rebar geometries that will make the structure more environmentally friendly.
Time-saving
Compared to the traditional method of arranging and working with steel rebars, these 3d printed structures are more convenient in several aspects. As they are easier to print whenever needed, the overhead of transportation is possible to optimize.
The ground workers will take less time arranging these rebars with concrete as the geometric structure is printed in a single piece. So, the additional work of putting rebars to the same level is waived off.
More affordable
Additive manufacturing is more cost-effective than manufacturing steel rebars as the traditional process is very capital-intensive. Along with manufacturing changes, manufacturers and buyers also need to pay the transportation cost that increases the price for the customers.
As the design is available in a CAD file, manufacturers don’t need to pay high charges for renting warehouses to keep the unused inventory. When there is less inventory storage, it will become easier to reduce the maintenance cost.
