The demand for 3D printed homes is increasing,
3D printed homes have revolutionized the way we think about building homes.
It offers a sustainable, cost-effective and highly customizable alternative to traditional construction methods.
The future of home construction has changed with 3D printing seamlessly replacing the traditional building system and pushing the current boundaries of innovation.
Synonymous with smart manufacturing, 3D printing is a prominent part of reshaping Industry 4.0 as we know it.
The global market for 3D printed homes was valued at US$13.84 billion in 2021.
It is expected to expand at a compound annual growth rate (CAGR) of 20.8% from 2022 to 2030.
Globally, 2.2 million units of 3D printers were shipped in 2021 and shipments are expected to reach 21.5 million units by 2030.
Competing to develop the best technology, industry players have become more involved in a space race of sorts – literally too, with even NASA adroitly using and reaping the benefits of 3D printing.
Benefits of 3D printing
As the construction industry faces times of uncertainty due to skilled worker shortages,
increasing costs, and a global housing shortage,
And areas affected by disasters and the impacts of climate change – the new digital and sustainable capabilities of additive manufacturing are here to help.
Because 3D printing allows for high design flexibility, it is easy to balance form, function and aesthetics.
There is no doubt that this process provides great potential for increasing efficiency and productivity.
Not only does it provide a high degree of planning reliability from the start,
Which reduces the chances of design errors and worker injuries – but also requires reduced coordination and monitoring efforts.
Construction time is significantly reduced with this, which also translates into lower costs.
Plus, its environmental benefits are endless. It – reduces the use of materials,
It uses natural, organic or recycled materials, generates less waste,
reduces transportation needs and also reduces carbon emissions.
How 3D printing works
Simply put, 3D shapes are initially designed through a computer-controlled process without the use of templates.
Using a large printing press skillfully, concrete or other materials are extruded from soil to mortar,
special polymers, recycled plastics and more layer by layer to easily form foundations,
walls, columns, stairs as well as other building elements.
Because this system is portable, it is well suited for off-site production, turnkey production and on-site application – eliminating the need for frequent transportation and calibration.
The type of materials that can be used in 3D printing
3D printed homes offer a wide range of material options that can be used to build these innovative structures.
One commonly used material is concrete, which is durable and readily available.
Concrete mixtures specifically designed for 3D printing allow printers to layer materials efficiently.
Another material gaining popularity is bioplastic, derived from renewable sources such as cornstarch or algae.
These materials are environmentally friendly and can be easily melted and extruded by printers.
In addition, composite materials, such as blends of fibers and resins,
are being explored due to their high strength-to-weight ratio and design flexibility.
It is worth noting that ongoing research and experimentation continues to expand the range of materials that can be used in 3D printed homes,
opening up the possibilities of sustainable and cost-effective construction.
To imagine a future in which 3D printing becomes the norm for mass housing,
there are still many challenges to overcome in order to replace traditional methods.
From adapting to countries’ stringent construction requirements, to addressing densely populated areas,
Responding to different weather conditions, improving the circularity of materials,
reducing carbon emissions, and making technology accessible to everyone.
However, it all starts with continued investment, exploration and innovation.
These successfully 3D printed homes are certainly pointing the industry in the right direction,
and although there is still a lot of potential that can be explored in other markets – it is clear that 3D construction printing is here to stay.
