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 â a.k.a. âConstruction 4.0â â 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. Itâs 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 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 printerâs 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
- 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 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 homeâs foundations in less than a few days, while traditional construction methods take several weeks or even months.
- Design flexibility: with a 3D construction printer, itâs possible to easily create curved walls and unique facades. (Good thing itâs 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 homesâ 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.

Autodesk may or may not be working on a construction 3D printer that uses metal material. This 3D printer, which is more a pair of robotic arms than a printer, is able to make metal components for construction sites. We canât wait to hear more about this!

CONCR3DE Armadillo stone 3D printer
CONCR3DE is a Dutch company that manufactures stone 3D printers. They are able to 3D print stone thanks to a special binder jetting process. Their two 3D printers, Armadillo Black and Armadillo White, aren’t able to print a house but can 3D print stone decorations or molds.
Discontinued projects and printers
Many startups have come and gone in the construction 3D printing industry.
D-Shape construction 3D printer
The D-Shape 3D printer is a multifunctional construction 3D printer that can 3D print very large objects, including houses and prototypes. D-Shape seems to be inactive since 2015.
Winsun house 3D printer
The Winsun 3D printer is a house 3D printer that was in the spotlight a few years ago. In 2015, however, Contour Craftingâs CEO accused Winsun of stealing their patented technology. Winsunâs website has since been taken down.
Cazza X1 3D printer
Cazza was founded in 2016 with their X1 construction 3D printer. However, it seems that one of the co-founders stole the companyâs funding in 2018, and Cazza is now on standby.
HuaShang Tengda
HuaShang Tengda 3D printed a house capable of withstanding a base 8 earthquake on the Richter magnitude scale. Today, the company seems to be off the radar.
3D printed house time and cost
Construction 3D printing is faster and more affordable than traditional construction methods.
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 houseâs 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 Corâs small house cost less than $10,000 to produce, and ICONâs compact 3D printed home even cost less than $4,000.
COBODâs cost calculator is a great tool for those who have specific projects in mind and are looking for a ballpark number.
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 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 worldâs 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.
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 worldâs 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
NASAâs 3D-Printed Habitat Challenge has given life to a number of teams dedicated to bringing 3D printing to space. Apis Cor, namely, won top prize for one of this projectâs 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 Muskâs SpaceX. It is possible that we will see the first space house 3D printers in space sometime in the next couple of decades (!).
