This project is a 3-year research, development and production project to explore the potential adoption of 3D concrete printing for construction in Singapore. The project is a collaboration of Robin Village, Nanyang Technological University and Witteveen+Bos, and is assigned by the lead agency Housing Development Board.
As part of the project, Witteveen+Bos, developed the 3D Concrete Printing System (3DCPS) for the HDB in Singapore. This 3D concrete printer is capable of printing concrete components up to 9 m long, 3.5 m wide and 3.8 m tall.
With this project, the possibilities and benefits of 3D Concrete Printing (3DCP) technology for precast elements production are explored, to push for higher construction productivity in Singapore. With the project is aimed to reduce dependency on foreign labour and improve overall construction productivity with a high level of automation.
If proven successful, it will offer more design options for HDB developments, and expand the capabilities in the construction industry. In addition, it will raise construction productivity, and reduce the dependency on conventional precast fabrication workers, thus addressing potential labour shortages.
The 3D-printer and the first fabricated object were visited in September 2019 by the Minster of National Development Mr. Lawrence Wong and the CEO of HDB, Mrs. Cheong-Chua Koon Hean. They witnessed a room-sized printed component of about 11 m2 (3.6 m long x 3 m width x 2.75 m high) in 13 printing hours, which was a successful product of the printing trials.
