A childcare center in Singapore had its exterior walls 3D printed in just two days, marking the latest case of the country promoting construction 3D printing technology.

The project was undertaken by Woh Hup, a well-known Singaporean construction company. Founded in 1927, the firm has participated in iconic projects such as Jewel Changi Airport and Gardens by the Bay. The building's first story was constructed using 3D printing, while the second story used traditional methods, as part of a condominium project in the Woodlands community.

According to The Straits Times, printing the first-story walls took two days, requiring only a six-person team to monitor sensors and inspect the process, totaling 170 man-hours. In contrast, traditional manual construction would have required nearly 400 man-hours and an 11-person team.

Du Hongjian from the National University of Singapore stated that 3D concrete printing can reduce manpower input, is more economical than traditional formwork, and offers architects greater design freedom. Additionally, construction can be carried out in the evenings, reducing noise pollution.

The structure underwent rigorous testing including compression and load-bearing to ensure safety. The research team is experimenting with incorporating 60% glass powder into the mix, which could reduce carbon dioxide emissions by half while maintaining the same strength. This provides a new solution to address the high cement content and carbon emissions associated with 3D printed concrete.
