Full sized 3D printed concrete Prefabricated Bathroom Unit (PBU)

Researchers from the Building ​and Constru​ction programme have developed the capability to 3D print an unfurnished bathroom in about 9 hours. They have also discovered that this method of 3D printing builds prefabricated bathroom units (PBU) about 30% more quickly and 30% lighter than current PBUs.

This innovation was ​developed b​y a joint research team led by Professor Tan Ming Jen in partnership with Sembcorp Design and Construction, and Sembcorp Architects & Engineers.

This Proof-of-Concept aims to improve productivity for Singapore's building and construction industry through the use of digital and robotic fabrication methods to reduce skilled labour and manpower requirements. Moving forward, the team looks to getting the PBU certified by the Building and Construction Authority of Singapore (BCA), and to commercialise the technology.
