3D printer for home construction

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.

*Category: some 3D printers are available for sale, others are working projects, and some are only available via a rental service.
**Type: construction 3D printers either use a gantry system (like oversized desktop 3D printers with X, Y, and Z axes) or a mechanical, robotic arm.

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).

Benefits of house 3D printing


3D printed houses can be built with organic, eco-friendly materials. Moreover, some house 3D printers use solar energy and generate low CO2 emissions.


House 3D printers can build affordable housing, being of great aid for people in poverty-stricken regions or after natural disasters.


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.


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.

Construction 3D printers: overview

We break down construction 3D printers into three categories: house 3D printers that are available for sale, concrete printer prototypes, and 3D concrete printing services.

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 (!).

Marketable Designs

We’ve been told that if the printer wasn’t any faster and wasn’t any cheaper to build with, it would still be the most significant tool ever, because it allows architects everywhere to begin offering designs that were cost prohibitive in the past.

Consumers are tired of the costs associated with conceptual designs. Traditional construction is limiting without astronomical costs. Architects have the ideas, but most consumers aren’t willing to pay for them. With a printer the cost between boring and amazing is the same.

How It Works


Concrete printing is possible with the construction of a large 3D printer capable of printing large scale structures, from spas and barbeques to homes and larger commercial buildings, without the need of traditional framing, forming or blocks. MudBots offers printers from 15' x 15' up to 100' x 100'.


There are hundreds of different mix formulas that closely resemble a mortar type mix. Each mix requires months of testing for different characteristics, such as fluidity, bonding, water impenetrability, Seismic resistance, as well as curing and strength. Mixes are designed for 1200 PSI up to 10,000 PSI, depending on the structure and engineered objectives.


First step is to decide what you want to print.


The next step is to conceptualize a 2D design using a CAD program, and then converting the design to a 3D model using any 3D software that can export an STL file.


Once the 3D model is ready, the STL file is imported into a slicing software, where the height of each printed pass is specified.

After slicing the model into individual print passes, the system exports the code which is interpreted into actual nozzle movement.


Electrical boxes and plumbing are added during the print leaving perfect finish without gaps.


The mix is batched on site after which, the liquid ingredients are added to the dry mixes and mixed for delivery to a computer-controlled pump, which works in unison with the printer to control nozzle speed, and the volume rate of material at the nozzle.


After printing the walls, windows and doors are cut out while the print is still green, leaving perfect openings for window/door casings.


The key to printing without stopping every 12" as seen by the rest of the world, is utilizing a batch plant that meters all the dry and liquid ingredients as the temperature, wind and humidity change. the mix formula being used at 5am is not the mix being used an hour later. MudBots provides a variety of mix formulas with differing strengths and cure times without being forced to buy proprietary mixes and paying 5 times as much when everything needed is already available at local batch plants.

Step 6

Add electrical boxes, rebar, and trowel walls while printing

Understanding What We Do & Don't Do

Here's how you can save.

Layout for Footings Dig

The first cost savings will be the elimination of 3 men, string lines, and marking paint. Simply add the airless attachment to the nozzle of the printer, and your entire layout for footing is done in minutes. Push the printer out of the way and start digging.

(The printer is able to print forms for footings)

Footing Forming

The layout and forming for footings and stem walls are very time-consuming. It takes a lot of lumber, diesel, stakes, and labor that is no longer necessary. Simply level the area, compact them, level the four corners of your printer, and PRINT.

(Forms do not need to be stripped when printed)

Footing Stripping

Perfect level and square forms are printed right from the computer. Grading is also easier, as the only real important level is the 4 corners of the printer. Printer can be set up for uneven grades.

(The printer can print the forms for slab)

Slab Forming

The slab layout and forming is critical to all other subs on the job. If a mistake is made at this point of the project, nothing else is square, and all other subs suffer. With the Concrete Printers, the house is square every time.

Slab Finishing

Not there yet, but our concrete printer will be finishing slabs within the next 6 to 12 months, and can be ordered as an option. If you’re waiting for all the options to be available before buying, you’ll never buy a printer, because we will never stop innovating. All upgrades will be available and are designed to be added to all of our printers.

(We can print basements)


Our printers easily print basement walls without the need of forming, backfilling, stripping forms, forming interior walls, drywall, insulation or taping. All of this is done by the printer.

(There is no need for the labor or time to do layout on slab)

Framing Layout

The printer knows where your wall is going to be. No chalk lines needed. Once the slab is poured, all you have to do is hit print.

(No need for framing)


No warped studs, better fire rating, no mildew. No matter how you look at it, printing a home is far better than framing a home. Concrete printing is faster, more accurate, just better all around.

(No need to drill studs for electrical)

Rough Electrical

This is not necessary as walls can be printed that are hollow. Depending on the mix that is used, there is also no need for rebar or solid pour exterior and bearing walls. We know the idea of exterior walls and bearing walls without rebar seems ridiculous, but it's time to learn something new. Look up 20,000 PSI concrete and geopolymer. It's real.

(No need to drill studs for plumbing)

Rough Plumbing

This isn’t necessary as walls can be printed hollow. Same as above. Your electrical and plumbing will be less expensive.

(Printed walls are finished without additive material during the print)


You will still need to hang the lid, but not the walls. This goes for the basement. Just trowel the printed wall and when done, it's as smooth as a 3-coat drywall. Most countries do not wood frame at all. They build with bricks and then send a crew of mason finishers, and when it’s done, it’s smooth as anything.

(No need for taping as the walls are troweled smooth during printing)


Some print finishes may not need to be finished if acceptable to the customer. Taping takes days for each coat to dry. This is not the case with mason finishing. Within 3 hours of the walls being printed, the walls are already finished.


If builders want to finish the smooth walls with a knock down broquet, orange peel or other finish, just come back the next day and spray with a hopper, top coat and trowel.

(Exterior walls are finished during the print)

Stucco / Siding

No paper, mesh or additive material is needed. This isn't a process that is done days after framing and sheeting. The finish is done real time as the wall is printing.

(Printers can be purchased with an insulation attatchment)


You can have any R Factor you want depending on the density and material. A solid concrete wall has an R9 Value. If you print a hollow wall and back fill with fiberglass, polystyrene or cellulose, you can achieve any R value you desire.

(Mudbots is working on a composite truss system that can be printed on site)


Additionally, house plans can be modified to allow for dome roofing, which can also eliminate trussing and sheeting costs. The truss system utilizes the same printer, but with the use of a different mixer/pumping system. As new advances become available, they will be bolt-on solutions with your existing printer.


More and more customers are starting to experiment with additional uses. Underground is definitely something worth considering. The cost is high for underground but can be significantly reduced by printing on site.

Landscape and Hardscape

The 3D Concrete Printer is a landscaper’s dream. Never before could you have offered products at a fraction the cost of your competition while still earning profits. It is basically unheard of. Developers will rethink their offerings when they realize how affordable the little extras are. The extras will set them apart from all the others.

Pool and Spa

By now, you may be realizing how significantly concrete printing is about to change so many industries. Pool and spa is just another market that will benefit. The cost for traditional pool construction is about to change. Homes can be sold with included water features at a fractional cost.


Very seldom do we see breathtaking signage. Everyone is looking for ways to stand out, but it keeps getting back to budgets. Imagine the development entries that are possible now. These printers like to print and with everything they can do, it would be foolish to have any down time.

Will It Pass Code?

First time callers don’t have any problem recognizing that concrete printing would be far faster and cheaper. They also don’t question the feasibility of learning the tech. The single most asked question relates to passing code. No fear of the tech, just fear of their building department.

Truth is concrete printers are already building homes and commercial buildings all around the world, so when considering the application in your backyard, here are a few things to consider.

ICF Construction

The best way to wrap your head around concrete printing is to start with the basics, and there is no better way than to liken 3D Concrete Printing, or 3DCP, to Insulated Concrete Block construction. ICF code is accepted everywhere yet a foam block has virtually no structural strength at all. So when you are considering how you would pass code, keep ICF in mind. For the most part, a concrete printer is doing nothing more than printing a hollow wall shell that can be filled with rebar and concrete. The only difference is foam has no strength at all, compared to what we print in most cases, which is twice the strength of cinderblock.

CMU Construction

Now with that in mind, let's look at the similarities with CMU (Cinderblock). No one questions the ability to build with cinderblock. While we don’t encourage it, take into consideration the fact that you can print walls that are the exact dimension and design as cinderblock yet twice as much the strength, and without grouted joints that are susceptible to seismic cracking.

The advantage of concrete printing is the ability to print hollow walls which reduced costs for electrical, plumbing and insulation. Additionally, hollow walls can be insulated to almost an R factor with ease with the absence obstructive studs.

The challenge isn’t whether or not it's possible, as it's already being done everywhere. The challenge is whether or not you can find a structural engineer that makes it possible. It's all about math. The code already exists, all you have to do is exceed the code, and to do that, you need to start with the mix.

Testing and Math

We have developed and tested a myriad of different mixes with different characteristics, such as PSI, tensile strength, water impenetrability, fire resistance, as well as cold weather mixes, hot weather mixes, accelerated mixes, and retarded mixes. We provide the formulas and the lab results that your engineer will need to determine what the wall designs will be. Once they have the testing results, they can design a wall that exceeds any code anywhere.

Some choose to stay close to traditional methods by printing walls that resemble ICF and CMU, but others, who have more confidence, take it all the way by utilizing stronger mixes, so that they can capitalize on ALL the cost-saving benefits.

Plans and Details

As for the other considerations, we have plenty of videos that address common questions about headers, attaching hurricane straps, installing electrical boxes, securing plumbing, mounting top plates for trussing and methods for tying the wall to the foundation. Although, most engineers want to see the methods being used by others first before reinventing the wheel, as they learn more and more until there isn’t a question that they can’t offer up to 4 or 5 solutions when asked. Most of this is common sense, nevertheless, we have the plan details and math to share.

As we’re saying this, bear in mind that every state, and sometimes even cities, have different building codes. What we will share is determined by specific code and conditions that are not specific to your state. Far too many factors come into play, such as mix characteristics, code, water table, frost level, annual snow loads, wind, seismic, soil compaction for starters. We do not provide structural engineering, but we can point you in the right direction.

What are your
Deal Breakers?

Everyone who is considering the use of concrete printing has a lot of work to do before they can commit to a purchase. There is no shortcut. The investment of time is inevitable. As you start down the path to making a decision, it’s easy to get confused as to what’s most important, and where you should spend your time, but as you consider the options presented to you, there will be some paths that obviously are a waste of time. Everyone needs to know what their deal breakers are. They will be different for each person, but from speaking with others, we have a pretty good idea of what most consider their deal breakers.


From the onset, our engineers understood the importance of creating a design that had all the same features but was also easily understood. A printer that is lightweight and easily assembled in the field. MudBots printers weigh 75% less than any printers in the industry, with an assembly time that is 80% faster. This is a printer that does it all, does it faster, and is half the price of anyone.

Basements and Second Story

In some parts of the world, the ability to print basements and a second story isn’t a big deal, but in North America, it’s essential. Look around and you will find that most printers in this marketplace don’t have the ability to do either without tremendous unnecessary excavation or back filling. If you’re going to invest in a printer, most agree that the ability to quickly set up for footings, basements and second story is a must.


Look at any other printer and you will recognize right off that assembly is going to be an expensive challenge. Imagine the worst IKEA assembly ever. That’s about what you get. Think about parts that are heavy to manage without forklifts and cranes, imagine hundreds of nuts and bolts. In some cases, needles cosmetic plastics that serve no function, waste hours of assembly, and will undoubtedly be broken and expensive to replace. Most printer designs make sense to the engineers that built them, but not so much to the contractors that will need to assemble it in the field. A 20' x 20' MudBots printer can be assembled with 2 workers in two hours without any mechanical lifting. MudBots can also be moved from one lot to another without disassembly by simply adding wheels. Additionally, the printer can print entire structures without being moved multiple times.

Proprietary Mixes

If you think your printer cartridges are expensive, wait until you have to buy and ship proprietary concrete mixes from halfway around the world or even the USA. MudBots is the only ones that provide the mix formulas for your printer and allow you to use any mix without voiding your warranty. This should be a deal breaker for everyone as they begin to realize what they will be paying for are mixes that are (mostly) available at their local hardware store, not to mention the cost of and any delay in shipping.

Customer Service

Does it feel like the others are sleeping on the job? There is far more to consider when thinking who to buy from than a few online videos and website. This is a significant purchase for most, but as you're out knocking on doors, the one thing you should consider the most is customer service. Start calling around and you’ll discover that there’s no one to talk to. Phone numbers are hidden, and emails go unanswered for weeks. You have to ask yourself, if no one will talk to you now when you have the money on hand, what’s it going to be like when you need support.


If you’ve been lucky enough to get this far with anyone, the first thing you will find is that MudBots isn’t just a little better in price. MudBots is 1/2 to 1/3 the price of other printers, with more features and options than anyone. Price is always a factor, as well as ROI. Do the numbers and you’ll find that within 60 days, you’ll have already paid for your printer in savings, and likely will be looking for your second purchase because of the advantages.


Most of our customers contact us because they are excited about the income possibilities that our printers will offer them, but for this very reason, the greater opportunity is in securing the exclusive distribution rights for their state. By merely owning and using our printers, our customers will undoubtedly generate tremendous excitement as they begin printing unbelievable designs at a third the cost and a third the time. It would be impossible to keep such a tool a secret. As news of this innovation begins making its way to the public, demand will become unimaginable. Since our customers are creating the exposure and excitement, it’s only right that they share in the success and residual income opportunity.


Most contracts start off with optimism and the best intentions, but if you’ve been doing this a while, you have learned that in the event of any legal actions, jurisdiction is an issue. If you’ve ever had to litigate outside your state, you recognize the challenges, but litigating outside the country is altogether different. We take a lot for granted in America, but that is not the case intentionally. Imagine trying to hire legal counsel abroad and trying to interpret international laws. This does not certainly offer home court advantage, and asking anyone who has tried, you’ll see that this is problematic at best. But even if you prevail, collecting on a judgement with corporate assets abroad is nearly impossible.

Master Dealer
  • We thought so!

  • Want more time with your family?

  • Want to earn over 100K a month?

  • Want to have your own company?

MudBots is looking for the best. If you have a background in construction, love new technology, and especially love business in general, you're in the right place. MudBots has developed the first line of 3D Concrete Printers available to the world. Media everywhere is saying that the new technology will change the construction industry forever. Seldom do opportunities come along with the huge market interest and untapped market. This is what business opportunist dream of.

Quality of Life

Success is measured in many ways, but true success is measured by the peace a person feels when they know they are doing something they love, their efforts are rewarded with increased gain, and they have the time to enjoy both with the ones they love. There are countless ways to make a living, but if you don’t enjoy what you’re doing or you don’t have the time to enjoy anything else, it’s hard to be satisfied. MudBots Master Dealers enjoy all three. They earn a remarkable living, they have the freedom to work when they want and because of their success, they get to focus on the more important things in life – their Family.

Job Description

The only way to manage a company that is growing as fast as MudBots is to have qualified individuals in every region of the country who can demonstrate products and serve their dealers. The Master Dealer program gives the company and its dealers the representation needed while offering a significant opportunity to those who embrace the call.

Exclusive Region

As an RMD, you will be given an exclusive license to represent and profit off of ALL the MudBots sales in your state/region. It is generally a full state, but in larger markets, a state may be divided to provide for better reachability and service.

Residual Income

There are many ways to profit as an RMD but the “residual commission” is by far the most enticing. Sell it once and continue earning for years to come. As an RMD you will earn up to 10% on every printer sold. With printers ranging from 284k to 1.3 million, it’s not hard to see how lucrative the venture can be. If RMDs sign up one new dealer every month who sells one printer a month within 12 months, depending on the profit sharing each RMD sets up with their dealers, earning after 12 months of work with 12 compliant dealers should be well over 100k a month. Why so much? Quite simply, we want to attract the best in the industry. An organization is only as good as its people. We want professionals, self-motivated individuals who are passionate about building their own business along ours.


One of the best thing about concrete printers is the recession-proof nature of products. If the economy slows, the need for faster and more affordable construction methods increases. Those trying to compete with traditional construction methods will quickly discover they can’t even come close, resulting in even more demand for MudBots products. Prospects can get on board now or wait until they are losing contracts without one.

3D printer for construction - the future or hype?

3D printing is one of the hottest technologies of the beginning of the century. Although the first primitive 3D printers appeared in the late 80s of the last century, only in the last 10-15 years have they become advanced (and cheap) enough to be widely used.

This technology is now used to print everything from plastic toys and mock-ups to complex parts of rockets and organs. The construction sector has not been ignored either: now dozens of companies are actively developing 3D printers for construction, some of which have already achieved considerable success and are using them in practice. And not only for creating benches and other street decor, but also for building houses.

Understanding what a construction 3D printer is - the future that has come, or a hype technology that will remain only in niche projects when interest subsides.

A 3D printer for construction is not much different from home devices on which children print plastic toys. But there are three significant differences: dimensions, consumables and, of course, price.

In fact, an industrial 3D printer for building houses is a CNC machine. Only instead of drilling holes or cutting metal with a laser, it applies a thin layer of consumable material along a given trajectory. Then another one is added on top of the first layer, and another, and another - and so on until the printer “prints” the three-dimensional model loaded into its memory layer by layer.

To do this, a 3D model, for example of a garden bench, is created in a CAD program. Then it is "cut" into thin layers, which in turn - from the bottom to the top - are sent to the "print".

The result is a design that is somewhat reminiscent of a layer cake. Only with large voids inside.

The principle of operation of a 3D printer for building a house is always the same:

  • applied a thin layer;
  • let it dry or gain the necessary strength;
  • applied the next coat;
  • and so on in a circle.

But the method of applying this layer and its composition are different. As well as the design of the printer itself, but more on that separately and a little lower.

So, when building with a 3D printer, consumables are usually applied in one of three ways: extrusion, powder method, or multi-jet modeling.


In this case, the finished mortar is extruded from the hopper through a special printhead that can move in three planes. The most common "printing" method for construction 3D printers.

Powder method

Two-stage 3D printing technology: powder mortar is applied first, and then special glue is applied. This allows you to get walls with a more even surface. In addition, the powder method is better adapted to field conditions - in particular, there is no risk of the building mixture solidifying in the nozzle in the event of a malfunction.

The technology is rather rare, since 3D construction printers for construction based on it are more complicated than extrusion devices.

Multi-Jet Modeling

A very rare 3D printing method used in just a few devices. This method is very similar to conventional inkjet printing: there are several hundred nozzles through which the mortar is squeezed out. The carriage, on which the nozzles are fixed, moves slowly and creates the desired pattern.

The main advantage of such a device is the speed of operation, which is several times or tens of times higher than that of an extruder printer.

There are actually more ways to print on construction 3D printers. After all, they are used not only for the construction of houses and the creation of decor, but also for the construction of complex metal structures, for example, bridges. But such machines are not the topic of this article - we are interested in private houses.

Most commonly used in construction 3D printers is modified concrete . But not ordinary, but special: with special additives, plasticizers, often with reinforcing elements. The result is a plastic mixture with a high degree of uniformity, which at the same time quickly hardens and gains strength.

Moreover, 3D concrete printers from different manufacturers use different mixtures for building a house. This is due to the fact that equipment developers select the composition of the building mixture so that it does not clog the nozzle, does not stick to it and comes out as a neat homogeneous mass without the formation of bubbles and other defects. And since extruders in general, and nozzles in particular, are unique for manufacturers, this also affects mixtures.

The second most popular type of building composition is various clay mixtures . They are used for two reasons: firstly, they are considered more environmentally friendly, and secondly, they are more affordable.

It does not really matter if the house is being built within the city limits or not far from the city. But the use of concrete mix severely limits the use of 3D printers in the construction of buildings located far from large cities, since many tons of consumables will then have to be transported along with the equipment. This is at least inconvenient and leads to additional costs. Not to mention the fact that mixing concrete for most construction 3D printers is possible only in factory or laboratory conditions, but not in the field.

Clay "seal" solves this problem for the most part - in this case, you only need to bring modifiers with you. This makes it possible, for example, to build houses with a 3D printer in remote areas of Russia.

In addition to clay, mixtures with earth, ash, straw are used for printing - this allows you to build houses actually from garbage and what you get on the site.

The least common 3D construction printers are inverted and use polyurethane foam insulating foam to build houses. That is, a 3D printer does not print walls, but a layer of insulation on them. At the same time, the operation of the device is stopped every 1-1.5 m of height and a concrete mixture is poured into the walls, using thermal insulation as a fixed formwork.

Such 3D construction printers are especially relevant in Russia, as they allow you to immediately solve the problem of home insulation. Moreover, among the heat-insulating materials used in private construction, polyurethane foam is the most effective.

There are four main types of construction 3D printers:

  1. Portal . Such 3D printers consist of at least two vertical stands and two horizontal rails between them. A carriage with an extruder attached to it moves along the resulting frame. This is a very robust design, but only objects that fit inside the frame can be "printed" with it.
  1. Compasses . Such a construction 3D printer is designed for the construction of large houses and structures at a distance from cities. It is a carriage that is put on a base that can rotate 360 ​​°.
  1. With arms. It's just a robotic "arm" that has been adapted for 3D printing. The most difficult to manage, but also the most flexible models.
  1. Delta . In this case, the extruder is suspended on three levers, which are fixed on racks. As a result, its position is determined by the position of the levers.

When building small houses using a 3D printer, portal models are usually used, less often circular ones. Delta devices are good for large or tall houses, and manipulators are good for creating small parts, for which positioning accuracy of the extruder is important.

The use of a 3D printer in construction is a new, but very promising technology. "Printed" houses:

  1. Cheap - "box" costs several thousand dollars.
  2. Can be built quickly - small houses can be completed in less than a day.
  3. Robust because they are virtually monolithic.
  4. They can be of almost any shape - the architect's imagination is limited only by the strength of the structure.
  5. Just like the picture - any CNC works with high precision, so the door and window openings will be exactly the same width as the project.

However, 3D printing is far from a magic wand. This technology has many disadvantages, and one of them makes it impossible to build with a 3D printer in Russia. Yes, and not only in it.

This disadvantage is standardization. In many countries of the world, technologies and requirements for building structures are strictly standardized. And Russia is one of the champions in this. At one time, the great Zaha Hadid was forced to change her Dominion Tower project in Moscow, because the concrete slab projections did not meet the standards. Whether it will be possible in Russia to put into operation a house that has not even been built, but printed on a construction 3D printer, is a rhetorical question.

Other minuses are also significant:

  • extremely expensive equipment;
  • finishing and other internal work, including the installation of engineering networks, still need to be done using traditional technologies;
  • need very skilled workers for quality control;
  • specific look that not everyone will like.

3D printing technology in construction is innovative and trendy, but so far has little to do with practice. Potentially, this is a way to quickly build incredibly cheap houses of any shape, even the most futuristic. In reality, this technology is still used sporadically, since even just buying a construction 3D printer is a huge investment. And the absence of references to this technology in the regulations makes it almost impossible to put such buildings into operation.

A 3D construction printer is a machine that can build houses by applying material (concrete) layer by layer. The paste type material used, in this case concrete or earth, is forced through the nozzle in layers to print buildings.
Concrete 3D printing in the construction industry saves time, effort and material when compared to traditional methods. However, it is important to note that 3D printers are not yet capable of creating a fully functional home, only the frame and walls can be created, other elements such as windows, electricity or plumbing must be installed separately. 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 the top 12 construction 3D printing solutions. Some of them are 3D printers already available for sale, while others are still in the prototype stage or provide 3D printing services for external structures.


Construction 3D printers use extrusion technology. Some construction 3D printers are similar to FFF/FDM desktop 3D printers, only larger (gantry style), while others consist of a rotating mechanical arm.
In both cases, paste-type components such as concrete are used as the filament. The material is ejected from a special nozzle to form layers. In simpler (very) extrusion of pasta is like using a bag to dispense frosting on a cake.
The printer builds foundations and walls layer by layer. The base is literally the printer's build plate. However, some concrete 3D printers are used to 3D print brick molds. Once molded, the bricks are stacked on top of each other manually (or with a robotic arm).
Benefits of building 3D printing
• Eco-friendliness : 3D printed houses can be built with sustainable materials. What's more, some construction 3D printers use solar energy and emit little CO2.
• Affordable: 3D construction printers can build affordable housing, providing great relief to people in poor areas or after natural disasters.
• Scalable: 3D construction printing reduces certain construction costs. For example, the cost of 1 square meter of wall using traditional construction methods is approximately $75, while for an Apis Cor house 3D printer it is only $27.
• Efficient: Because materials are 3D printed on demand, machines produce less waste. In addition, 3D construction printers can complete the foundation of a house in less than a few days, while traditional construction methods take weeks or even months.
• Design flexibility: Curved walls and unique facades can be easily created with a 3D printer
Disadvantages of 3D construction
• Expensive initial investment: These 3D printers can sometimes cost up to a million dollars.
• Partially built houses: only the frame houses are built. The 3D printing process is usually paused to manually install plumbing, wiring, and fittings.
• Rough appearance : The exterior of most 3D printed houses is not as smooth as traditional houses.
• Lack of Certification: Construction sites are regulated by law and there are important safety standards that must be met, which can be difficult with 3D printing methods (different repeatability, dimensional stability, etc.).


We divide construction 3D printers into three categories: house building 3D printers that you can buy, prototype concrete printers, and concrete 3D printing services.
