A few examples of 3D printed houses & offices do exist, but 3D Construction is a long way from being the default technique of constructing houses or structures. 3D printers may also print or pre-fabricate parts of a building in a factory which can then be put together later at the construction site. 3D printing can help the Construction embrace the ‘lean’ concept of manufacturing. 3D printers on the other hand only use materials required to print the structure, drastically reducing cost & generating zero waste. The same applies to construction where buildings with unique architecture can be 3D printed, something traditional methods may find challenging. Although the idea of 3D printing houses or buildings sounds appealing, the technology is still at a nascent stage in the industry & wide-scale adoption remains mired with several hurdles.
