Product Highlights : 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 printers 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 homes foundations in less than a few days, while traditional construction methods take several weeks or even months.
• Design flexibility: with a 3D construction printer, its possible to easily create curved walls and unique facades. (Good thing its 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.
