No one does big scale like the Chinese. A Shanghai tech company 3D-printed an entire six storey high apartment and mansions. Can you beat that!?

The large scale structures were produced, piece-by-piece, using an offsite machine measuring 7m tall, 10m wide and 40m long, and then put together at the Suzhou industrial park. A specially formulated ink made up of concrete, fiberglass, sand and a hardening agent, is used as it is flexible, self-insulating and is resistant to strong earthquakes. This efficient construction method saves 60% of the materials, 70% of the time and 80% of the labour needed when compared to building a typical home, and are aiming to establish many affordable homes across china, in the future.

I think HDB should start considering 3D printed public housing as a means of bringing down home prices in Singapore.
