3D printing technology has led to the creation of an amazing array of three-dimensional objects and now it's being used to create something on a much larger scale — the house of your dreams.
The future of home building may be headed toward a 3D printing revolution with the technology being used to build homes at half the time and at half the price of traditional construction. It just might be an emerging market that builders and buyers simply cannot ignore.
Jason Ballard, co-founder and CEO of ICON, a construction technologies company that uses 3D printing to create homes, told Weekend TODAY that picking out the house you want can be as simple as selecting a design and pushing print.

"3D printing is taking a digital file of a house design and layer by layer, depositing material to build up the house in three dimensions, one layer at a time," Ballard told NBC's Kathy Park.
And unlike traditional homes, which can take weeks or even months to frame out, the walls and foundation of a 3D-printed home can be ready in as little as two days, with only a three or four person crew. All of these factors brings the production costs of a 3D-printed house down to as little as $4,000 per unit.
3D-printed homes are a cost-effective way to build from the ground up. Production costs for one 3D-printed home can be as low as $4,000.TODAYCompanies like ICON are creating homes from the ground up, using a massive printer and a special concrete formula.
The proprietary concrete used to make the homes is inherently resilient and this cost-effective yet sturdy construction could help make homes nationwide more affordable, making it a major contender in the fight against homelessness and the effects of climate change.
"My hometown's been destroyed multiple times by hurricanes and tropical storms," said Ballard. "I've spent Christmas in a FEMA trailer. An ounce of prevention is worth a pound of cure," he added, pointing out that it takes a lot of money and time for a town to try and recover from disasters.
3D printing might be a solution for the country's housing shortage and homeless crisis.TODAYICON built the nation's first community of 3D homes in Austin, Texas to uplift the local homeless population.
Tim Shea was the first person to move in.
"I could never have imagined from where I came from that I would ever have this beautiful a place to live in," he told TODAY.
"I'm so thankful."
3D homes are starting to hit the wider market. On Long Island, New York, SQ4D constructed the first 3D-printed home for sale to the public.
"We're trying to build houses in half the time for half the price," SQ4D's director of operations Kirk Andersen said. "Our profits will be higher and we'll be able to show that with more projects that we do."
A three-bedroom, 2-bathroom house built in just two days using 3D printing technology was listed for just under $300,000 — approximately half the cost of a comparable home in the same area. Offers poured in by the thousands.
"It's just impossible to find anything at this price," said potential buyer Mitch Johnson.
"And this quality," added Patty Johnson.
And with a housing shortage and a labor shortage, it seems that 3D-printed homes couldn't have come at a better time.

Ultimate guide to construction 3D printers in 2022 (concrete 3D printing)
What are the best house 3D printers?
A construction 3D printer is a machine that can build houses by depositing a material (concrete for example) layer by layer. Concrete 3D printing – a.k.a. “Construction 4.0” – is a similar 3D printing technology to the one that FFF 3D printers use. Paste-type material, in this case, concrete or earth materials, is pushed through a nozzle in layers to print buildings in 3D.
Concrete 3D printing in the construction industry helps save time, effort, and material compared to traditional construction methods.
It’s important to note, though, that 3D printers are not yet capable of creating a fully functional house.
Only the frame and walls of the house are built; other elements, such as windows, electricity, or plumbing, need to be installed separately. But concrete 3D printers can also be used to print bridges, benches, or simply outdoor decorations.
To provide a complete overview of the construction 3D printer market, we have listed 12 house 3D printing solutions. Some of them are 3D printers available for sale, while some are still at the start-up prototype stage or are external construction 3D printing services.

How to build 3D printed houses?
Here we explain how 3D printers are able to print houses with paste extrusion.
House 3D printing technology
House 3D printers use extrusion technology. Some construction 3D printers look like super-sized desktop FFF/FDM 3D printers (gantry style), whereas others consist of a rotating mechanical arm.
In both cases, paste-type components such as concrete are used as filament. The material is pushed out of a special nozzle to form layers. To put it (very) simply, paste extrusion is similar to using a piping bag to spread frosting on a cake.
The printer creates the foundations and walls of the house or building, layer by layer. The ground is literally the printer’s build plate. Some concrete 3D printers, however, are used to 3D print brick molds. When molded, the bricks are then piled atop each other manually (or with a robotic arm).

Eco-friendly
3D printed houses can be built with organic, eco-friendly materials.
Moreover, some house 3D printers use solar energy and generate low CO2 emissions.
Affordable
House 3D printers can build affordable housing, being of great aid for people in poverty-stricken regions or after natural disasters.
Scalable
Construction 3D printing reduces certain building costs. For example, the cost for 1 square meter of a wall using traditional construction methods is approximately $75, whereas with the Apis Cor house 3D printer it is only $27.
Efficient
Since the materials are 3D printed on-demand, the machines produce less waste. Also, construction 3D printers can finish a home’s foundations in less than a few days, while traditional construction methods take several weeks or even months.
Design flexibility
With a 3D construction printer, it’s possible to easily create curved walls and unique facades. (Good thing it’s possible to 3D print furniture to match the curves!)
Limits of 3D printing houses
Expensive initial investment
House 3D printers can sometimes cost up to one million dollars.
Partially-built houses
House 3D printers only build house frames. The 3D printing process is usually paused to manually settle plumbing, wiring, and rebars.
Rough exterior
Most 3D printed homes’ exteriors are not as smooth as traditionally-built houses.
Lack of certification
Construction sites are regulated by laws and there are important safety standards that need to be met, which can be challenging with 3D printing techniques (varying repeatability, dimensional stability, etc.).
Another downside that has been noted over the years is that house 3D printing can potentially harm local economies, especially in poverty-stricken regions or cities with high unemployment rates. Indeed, since construction 3D printers reduce the need for manual labor, they create much less employment for local workers.
Differences between 3D printed houses and traditional houses
Concrete 3D printing saves time, uses less material, and requires less manual labor.
Even 3D printed houses have a rougher exterior, post-processing is an option just as it is for regular 3D printed objects. 3D printed houses tend to be smaller due to 3D printer build volume limits, but this is not always the case.

3D printed house time and cost
Construction 3D printing is faster and more affordable than traditional construction methods.
However, since construction 3D printing is still in its early years, it is difficult to provide definitive statements about how long it takes to 3D print a house and how much it costs to 3D print a house.
How long does it take to 3D print a house?
Various construction 3D printer manufacturers such as Apis Cor or ICON boast that they are able to 3D print a small house in 24 hours. As mentioned before though, print jobs generally only include laying down the house’s foundations and walls.
This does save whatever amount of time it usually takes for a standard team to build walls for a certain project. The rest of the timeframe for building a house remains equal.
3D printed house price
In general, it is estimated that a 3D printed house costs 30% to 55% less than a traditionally-built house.
For reference, Apis Cor’s small house cost less than $10,000 to produce, and ICON’s compact 3D printed home even cost less than $4,000.
Construction 3D printer price
A construction 3D printer can cost anywhere between around $180K to over $1M. Robotic arm systems tend to have higher price tags than gantry-type systems.
Other 3D printed infrastructures
Aside from housing or buildings, construction 3D printers are able to 3D print bridges and space-station infrastructures.
3D printed bridges
Construction 3D printers can also 3D print bridges. In 2015, the world’s first 3D printed steel bridge was 3D printed for testing in Amsterdam by MX3D. MX3D printed the final version of their stainless steel bridge in 2018 and installed it in Summer 2021.
In 2017, a 12-meter-long pedestrian bridge was 3D printed in Madrid, Spain. In the same year, the first 3D printed concrete bridge was built in the village of Gemert in the Netherlands.
More recently, in 2019, Shanghai became home to the world’s longest concrete 3D printed bridge. It is 26.3-meters long and 2.6-meters wide, and was 3D printed in only 18 days.
3D printed infrastructures in space
NASA’s 3D-Printed Habitat Challenge has given life to a number of teams dedicated to bringing 3D printing to space. Apis Cor, namely, won the top prize for one of this project’s phases. The goal is to create sustainable and efficient 3D printed housing for deep space exploration.
Many other companies have been involved in space-building projects, including the European Space Agency and Elon Musk’s SpaceX. It is possible that we will see the first space house 3D printers in space sometime in the next couple of decades (!).

Is concrete 3D printing just for houses?
No, concrete 3D printing is also for infrastructures such as bridges.
Construction 3D printing is waiting for a breakthrough The first construction projects using this technology appeared only in 2014.
We are talking, first of all, about the so-called small architectural forms (benches, flower beds, fences). They never even dreamed about building houses. But already in 2015, the Russian startup Apis Cor made a splash - it printed a whole house in the Moscow region. Since then, news about new 3D printed houses has periodically appeared. However, despite the fact that the technology proved to be very promising in terms of the speed of construction of housing and the reduction in the cost of construction, no mass implementation followed. Construction is the world's number one market. And, if many technological innovations are being introduced in the field of high-rise construction, then little has changed in the field of low-rise construction over the past decades. The last 30 years have seen the availability of the Internet, mobile phones, mobile internet, robotics taken to a new level, etc., but when you get to a house construction site, you are unlikely to find many technological innovations.
Automation is practically non-existent, and manual labor prevails. 2020 was a test of strength for the whole world, and also led to the highest level of inflation, which, first of all, hit the construction market, there was a dramatic change in prices for metals, cement, wood and much more.
This Internet meme shows what happened to the cost of building materials in just a year. And the process is still going on. At the same time, there is a serious rise in the cost of labor, and there is an acute shortage of it. All this leads to a sharp rise in the cost of building houses. No matter how strange it may sound, statistics show that the growth of automation does not occur when everything is fine, but precisely in crisis situations, during increased competition, reduced demand and the need to urgently look for new technologies to increase production efficiency. So it happened this time, and after some stagnation, construction 3D printing received a new impetus for development.
Preparing to write an article, I turned to the founder of Arkon - Boris Kozlov y.
Arkon was established in 2020 and is engaged in the production of construction 3D printers, both a workshop type for creating prefabs (prefabricated houses) and a portal one capable of printing a two-story house. I asked Boris the key, in my opinion, question:
- Construction 3D printing appeared in 2014, but no mass introduction of this technology followed in 7-8 years. Why do you think this happened, and why is there a surge of new projects right now?
- It seems to me that the reason is the snowball effect. The technology had to mature, grow from a hypothesis to a pilot implementation, and finally to commercialization and scaling (what is happening now). In addition, it should be borne in mind that construction is one of the most conservative industries, where, unlike even aviation and the automotive industry, there is still an extremely low introduction of digital solutions and automation in the field of the production process itself - the construction itself.
The issue of regulation and certification also plays an important role - this process is long and creates an additional lag.
In 2014-2016 the first samples of building 3D printers and prototypes of printed buildings appeared. The concepts of various form factors of construction 3D printers and types of printing materials were tested.
In 2017-2018 in the world, the first notable investments were made in a number of construction 3D printing start-ups. Further, by 2020, these investments "rolled" in the form of reaching a certain level of technology maturity - the first commercial products (3D printers and houses) appeared.
Finally, in 2020-2022 it became clear that the hypotheses of the effectiveness of construction 3D printing were justified (cheaper, faster, more environmentally friendly), and large investments began in the industry. A striking example is the investment of GE (the French division of General Electric) in the Danish COBOD or the achievement of a capitalization of $ 2 billion by the American company ICON.
In 2022-2023 over 1,000 buildings will be printed worldwide already, scaling from single buildings/pilot projects to entire villages and major infrastructure/reinforced concrete implementations. In addition, in a number of countries, by now, a regulatory framework has been created or is being actively created for the introduction of additive technologies in the construction industry.
Thus, I believe that the specified time period is a fairly natural cycle of technology development, which is likely to experience exponential growth in the next decade.
According to ResearchAndMarket report, the global construction 3D printing market is valued at USD 354.3 million in 2022 and is projected to reach USD 11068.1 million by 2027, growing by 99.04%.
Various market processes affect the prices and behavior of participants in the global 3D construction printing market. They create price signals that are the result of changes in the demand and supply curves for a product or service.
They can be associated with both macroeconomic and microeconomic factors. Even human emotions can also drive decisions, influence the market, and create price signals.
Now let's take a quick look at what the construction 3D printer is. Without delving too deeply into the technology, we can say that construction 3D printers are very similar to classic FDM/FFF printers that print with plastic, but instead of plastic, the material here is a cement mixture, which is fed directly into the nozzle and forms an object by layer-by-layer overlay. Printers are also portal, on the basis of a flying boom, with a robotic arm.
Pictured left is a construction printer based on a boom. The figure on the right is a gantry construction 3D printer
In the figure above, a construction 3D printer in the form of a robot arm installed on a mobile platform.
Everything changed completely when, in the summer of 2021, the American company ICON, which was trying to introduce 3D printing into the construction of various auxiliary facilities, signed a contract with one of the largest American developers, Lennar, to build a village of 100 houses in Texas and immediately became a unicorn , having received 200 million dollars of investments from several investment funds.
At the same time, the Danish company COBOD, created by the world's largest construction formwork company PERRI, began selling its gantry 3D construction printers and participating in construction projects around the world. In the photo below, a modern two-story house built in Germany and a school building in Malawi, built in record time with a minimal budget.
Few things unite developed, developing and poor countries, everywhere their problems and tasks, but Affordable housing shortage is a global agenda . If in poor countries there is an acute problem with the increase in the number of homeless people due to a lack of housing, as such, then in developing countries it is necessary to dramatically accelerate the number of new housing being built to meet the needs of a growing population. In developed countries, the problem is primarily in the cost of housing, which has risen in price to such an extent that it has become practically inaccessible to young people.
And with the simultaneous increase in life expectancy in these countries, this problem is only getting worse.
At the same time, the trend towards "green agenda " is developing, reducing CO2 emissions, building with more environmentally friendly materials, etc. But, unfortunately, so far the construction industry is the absolute leader in CO2 emissions, as well as in the amount of garbage that each construction site leaves behind. This is not to say that construction 3D printing solves all these problems, but at least it is moving in the right direction. Let's look at this with a few illustrative examples.
3D printed walls. Today, when we talk about 3D printing houses, we are talking about printing walls. Everything else (foundation, windows, doors, ceilings and roof) is done in the traditional way. 3D printed walls are built as fixed formwork, which significantly saves the amount of cement used , and this, in turn, reduces the cost of construction and reduces the environmental impact of cement production.
In addition, with this method of construction, no additional waste is produced, the strength of the structure does not suffer. It can be reinforced, as shown in the photo on the left, and engineering communications can be immediately laid, as shown in the photo on the right, which also affects the final speed of the construction of the object. At the same time, the total weight of the structure is reduced, the remaining cavities can be filled with lightweight foam concrete, insulation, straw or any other available material. Such a lightweight design can use a lighter foundation. The construction method itself is more economical in terms of material, and therefore environmentally friendly.
Eco-concrete with the addition of polymers is being actively developed, the production of which reduces CO2 emissions from 30% to 100%. The Apis Cor company mentioned at the beginning of the article, which built a house in the suburbs in 2015, is now based in hot Florida, plans to start using this material in its projects.
Another startup from Russia, Mighty Buildings, headquartered in California, initially relied on a polymer with the addition of mineral chips. And while the company doesn't build entire homes, it only makes wall panels, it has won numerous design awards, as well as a $400 million valuation in several investment rounds.
As a result, with a rough calculation, we can say that the total savings on the construction of walls can reach 30%, and the total cost of the house can be reduced by 10%. This is true for houses designed for conventional construction. And if you initially design with 3D printing, you can improve this ratio by optimizing the laying of communications, the ability to immediately print interior walls, bookmark niches for bathrooms, fireplaces, built-in wardrobes and kitchens, as was done in the house built by COBOD in Germany.
"There are spots on the sun." Despite all the advantages of construction 3D printing, has several significant disadvantages of .
The main one is layering, which cannot be avoided at the current level of technology development.
The photo above shows the layering of the 3D printed walls.
This task can be worked in several directions:
-
Ribbed walls can be plastered, painted and played with as a design element. That's how ICON does it in the US, for example their latest project House Zero is done that way and has won a number of design awards.
-
Use special "shutters" on the print head that allow smooth layers, as COBOD and other manufacturers do. The photo below shows that this does not ensure the complete absence of layering.
-
Fully sand the surface to get the usual smooth wall for plastering, painting, wallpapering or other finishing. It is possible, but it will require huge labor costs, which can reduce the overall efficiency of using 3D printing.
Pictured above is a 3D printed wall sanded smooth.
The second problem is the required temperature. Ideally, printing should take place at temperatures between +5C° and +30C°. Humidity is also important. Using additives, you can push these boundaries, but not indefinitely. At strong sub-zero temperatures, printing will be possible in the field only if the construction site is covered with a dome and the required temperature is reached inside with the help of heat guns. In conditions of intense heat, it is preferable to print at night. Another solution could be to print the wall panels in the shop and assemble them on site. Of course, each of these decisions will have a negative impact on the economic efficiency of the project.
Building 3D printing can be useful not only for the construction of houses . With its help, you can solve many other problems, and there its disadvantages will not matter. For example, the American concern GE uses COBOD printers to build towers for wind turbines in the shop. Ribbed surface and temperature restrictions in this case do not play any role.
Construction takes place in the shop, after which the object is transported to the installation site.
Construction 3D printing, or, as it is also called, additive construction, has just appeared, and I want to believe in its bright future. There are many prerequisites for this, but a lot still needs to be done for success. First of all, it is necessary to develop principles for designing houses for building 3D printing. Then it is necessary to attract top architects to create landmark projects, which can be followed by the mass introduction of a new and very promising technology. Construction 3D printing could help solve the global housing shortage and bring more automation to other areas of construction.

How much does a house printed on a 3D printer cost?
3DPrintStory News How much does a 3D printed house cost?
Every new innovation comes to market with a price.
For example, large concrete 3D printers had a fairly high price when they first launched. But as with most technology, prices are falling as new, better, and more affordable products are developed. New innovative concrete mixtures also contribute to lower prices.
Since there are a number of 3D printed building projects around the world, it is impossible to give an exact price for a 3D printed house. Instead, we'll take a look at some of the most recent and promising projects and their prices.
However, in general, jumping ahead a bit, you'll see that a 3D printed house can cost as little as $10,000, sometimes less. Let's take a look!

One rather promising project from Russia. Apis Cor is a Russian company that specializes in the development of a mobile 3D construction printer capable of printing entire buildings on the spot.
Apis Cor built a 410 square foot home to showcase the potential and capabilities of its mobile 3D construction printer.
The 3D-printed house cost the company about $10,150 - an incredibly low amount for building a house.
Here is a more detailed list of costs, according to the company's website:
- Foundation: $277
- Walls: $1624
- Floor and roof: $2434
- Wiring: $242
- Windows and doors: 242 $
- Exterior: $831
- Interior (including stretch ceiling): $1,178.
The company even decorated the house both inside and out. The outside of the house is painted, but inside there is a refrigerator, a large-screen TV, a sofa and other furniture. True, furniture is clearly not included in the price. Apis Cor just wanted to showcase what a finished home could look like.
Example 2. Is ICON a house for less than $4,000?
Look at the picture above. This house was 3D printed by Texas-based ICON.
ICON specializes in low cost building solutions, so their main project is a 3D printed house.
In partnership with the non-profit organization New Story, ICON plans to build an entire block of these affordable 3D printed homes in El Salvador.
The goal is to provide housing for people who, unfortunately, do not yet have adequate housing conditions.
A prototype 3D printed house cost about $10,000, but the company claims it can bring that down to $4,000, which is amazing and impressive news. The approximate assembly time for such a house from ICON is approximately 24 hours.
Example 3 Winsum - 10 houses in one day
Winsun from Shanghai became famous in 2014 by reaching the 3D printing milestone of 10 houses in just one day!
Winsun used large concrete 3D printers, 10 meters wide and 6.6 meters high. The company said that each 3D printed house costs $4,800, which is surprisingly low for 2014!
Although Winsun's 3D houses are not so exquisite, they have generated a lot of public interest. This project has definitely contributed to the increase in the number of houses made with 3D printers and the development of 3D printers themselves for their production.
Winsun is also known for producing one of the most advanced 3D printed buildings to date, which we will discuss in the next section.
..
Example 4 Office Building in Dubai in the world, printed on a 3D printer. What it is? Beautiful and futuristic office building in Dubai.
The entire 3D printing process took Winsun only 17 days. Up to this point, we have mentioned fairly cheap 3D printed houses, but this building was clearly more expensive - around $140,000. However, compared to what it would have cost had it not been 3D printed, the final price is impressively low.
Conclusions
As we mentioned above, it is difficult to give an exact price for 3D printing at home, since the price depends on the size and complexity of the design.
But keep in mind that these days you can 3D print a house for as little as $4,000. This price covers the frame of the house (base, walls, roof) and, in some cases, wiring.
As you may have noticed, the cost of an office building in Dubai is quite high compared to cheaper and smaller 3D printed houses. For high-tech concrete 3D printed projects, expect construction costs to be around $100,000, which is actually quite low compared to the cost of building the same building using traditional building techniques.
