I came across an interesting article online about a house built by 3D printer. So, I would like to summarize and share some of the interesting points here.
An innovative technology, which we build a house with a printer, has recently been attracting a lot of attention in the construction industry. The house is called "3D printer houses" and it is said that the technology defies conventional wisdom. The start-up company in the United States built a house with 3D printer in Russia in 2017 and it was the world's first. The total floor area of the house was 38 square meters. It only took 24 hours to complete and only costed about 10 thousands dollars. The 3D printer was huge and installed directly in the construction site. It also only needed two operators. The way to build a house formed a shape by stacking concrete with layer by layer. As a side note, the roof and windows were set by people. That's why 3D printer house has some benefits as follows
1) A construction speed is extremely fast: Conventional construction takes a few months to complete a framework, but 3D printer houses only takes a day.
2) A cost is much cheaper: It can lower material costs and don't need much manpower.
3) Design is flexible: A printer allows construction to form complicated curve and free shape.
4) A house uses concrete materials and is durable : It is strong against fire, strong wing and torrential rain.
However, the artcle said a construction in Japan needs to follow the Japanese Building Standards Act. As of now, it's highly unlikely that a 3D printer house gets an approval. On top of that, Japan is prone to earthquakes and a 3D printer house needs further improvement for that in the future. I think the cost of many things including materials has drastically raise. That should be tough for young generation and is making hard to build a house. That's why I really hope this method will expand in Japan in the near future.
