Recently, we reported that Lennar was using 3D printing to build homes in Austin. In 2014, the BBC reported that China was printing up to 10 homes a day at the low cost of $5000 per home. This trend is making strides in the real estate market, even though there’s still a long way to go. In a move that should give the industry confidence in 3D printing, Indonesia’s Public Works and Public Housing (PUPR) Ministry announced that they are using concrete 3D printing to build homes in rural areas. Eventually, plans are in the works to construct schools.
Using 3D printing to build an infrastructure
Indonesia is the world’s fourth most populous country. As with most countries, housing expenses are climbing in both urban and rural areas. According to Habitat for Humanity, 11.3% of the population lives below the poverty line. For comparison, in September, the U.S. Census Bureau released information that the U.S poverty rate increased to 11.4%, one percentage point over the same time in 2020. Affordable housing is a problem in Indonesia.
“This technology really helps us, so we can build faster, more accurately, and with precision,’ explains Kusumastuti, Indonesia’s Director General of Human Settlements.” The PUPR reports that 3D printing reduces waste and improves construction quality. Considering that up to 70% of housing is built by individuals, not private developers or the government, using 3D printing under the PUPR Ministry is an upgrade in a country that deals with many types of economic disasters, due to its climate.
3D printing’s potential for real estate
As 3D printing is used in more construction projects, not only in the U.S. and China, it’s hoped that the real estate industry embraces the technology. Indonesia isn’t the only country that is trying out 3D printing. 14Trees constructed a school in Malawi using this method already, with the project taking around 18 hours. The company is undertaking more projects in Africa using this technology and more companies are building houses using 3D printing in the United States. It will be exciting to watch how this plays out in the various markets.
