The Era of Robot House-Building Has Arrived! American 3D Printed Homes Sold for 1.47 Million Ringgit

In the United States, where housing prices remain high and there is a severe housing shortage, an entirely new construction technology is drawing attention.

According to the New York Post, a California start-up has announced that they have completed the first batch of homes in the area built entirely with 3D printing technology. Thanks to significant savings in labor and construction time, these houses are selling at prices clearly lower than market rates, with the first home listed at only $375,000 (about 1.47 million ringgit).

Industry insiders believe this technology may mark a major shift in how houses are built in the US — making construction faster and cheaper in the future.

The house does not use traditional wood framing or large construction crews, but was instead built by layering concrete using industrial-grade 3D printing equipment. The entire process resembles that of a giant "printer," where an automated system stacks materials layer by layer according to design blueprints, ultimately forming the structure of the house walls.

The house is located in an experimental community in Yuba County, north of Sacramento, California. The developer plans to build a total of five 3D-printed homes in the area.

Lin Nan, founder of 4Dify, told CBS News that this home has an area of about 1,000 square feet (approximately 93 square meters), and it only took 24 days to print from start to finish. In comparison, building a traditional home in California often takes months or even years.

The developer points out that the biggest advantage of automated construction is the significant drop in costs.

3D printed buildings can greatly reduce labor needs, shorten construction periods, and cut down on material waste, which means the final home price is clearly lower than the local market. According to reports, this particular house has already been listed for sale at $375,000. In California, where housing prices often reach several hundred thousand or even millions of dollars, this price is considered highly attractive.

This technology was developed by SQ4D, whose core equipment is a 3D printing machine called ARCS (Automated Robotic Construction System).

The system can complete large-area concrete structure construction with minimal human labor.

The development team says that such houses are not only fast to build, but also offer multiple advantages. The concrete structure is stronger, offers better fire resistance, is mold and pest-proof, and is cheaper to maintain. Due to higher safety, it may even result in lower home insurance costs.

The development team notes that currently, the first house takes about 24 days to print, but as the technology matures, the construction period could be cut to just 10 days in the future.

High construction costs, expensive labor, and complex approval processes have long made it difficult for housing supply to keep up with demand. Some experts believe that if 3D printing construction technology can be widely adopted, it may become a new solution to the housing crisis in the future.
