In the Wolf Ranch community in Georgetown, Texas, 100 single-storey houses are being built using the Vulcan printer from ICON. This 3D printer builds the houses layer by layer from a special concrete mix that is robust and weather-resistant. The construction process saves time and labour while creating walls that can withstand extreme weather conditions.
Resilience and modern challenges
The solid concrete walls of the houses not only offer excellent protection against extreme weather conditions, but also provide excellent insulation. This construction proves particularly useful in hot summer months, as the interiors remain cool and the air conditioning systems are relieved. However, the thick walls also pose challenges: the signal strength of wireless networks is impaired, which is why many residents rely on meshed routers.
Building revolution
The Wolf Ranch homes, known as the “Genesis Collection”, are available for between 450,000 and 600,000 dollars, and a quarter of the units have already been sold. The project demonstrates the potential of 3D printing to change the construction industry for good. ICON already built its first 3D-printed house in Austin in 2018 and is even planning to use the technology on the moon as part of NASA’s Artemis programme in the future.
3D printing on the upswing worldwide
3D printing in the construction industry is also picking up speed in Germany. the first 3D-printed detached house was opened in Beckum in 2021, and further projects, such as the publicly subsidised apartment block in Lünen, are in the pipeline. These developments show that 3D printing is becoming increasingly important worldwide and will potentially shape the future of construction.
