Ecological: 3D printed homes can be built with organic and environmentally friendly materials. In addition, some 3D concrete printers use solar energy and generate low CO2 emissions.
Affordable : 3D home printers can build inexpensive homes with organic materials, which holds great promise for regions of the world affected by poverty or natural disasters.
Economies of scale : 3D home printing reduces some construction costs. Thus, the price of a square meter of the wall is about $ 75 with traditional construction methods, while it can go down to $ 27 with the Apis Cor 3D printer.
Effective : Because the materials needed for 3D home printing are printed on demand, machines produce less waste. In addition, 3D construction printers can finish the foundations of a home in a few days, while traditional construction methods take weeks or even months.
Flexible : With a 3D concrete printer, it’s easy to create curved walls and unique façades. (Fortunately, it is possible to print furniture in 3D so that they are adapted to curves!)
Limitations of 3D building printing
Costly initial investment: The price of a home 3D printer can reach up to a million dollars.
Partial Construction: 3D home printers only build the building’s frame. The 3D printing process is usually interrupted to install plumbing, electricity, and rebar manually.
Uneven exterior surface: Most exterior surfaces of 3D printed houses are not as smooth as those of traditional homes.
Lack of certification: construction sites are regulated by law. There are many important safety standards to follow, which can be difficult with 3D printing techniques (variable repeatability, dimensional stability, etc.).
