節約成本 美國公司擬3D打印住宅

A pair of companies in the US are working on solving their model of quickly 3D-printing house.

美國兩家公司正在着手解決快速打印3D房屋的問題。

Eventually their goal is to bring the cost down significantly by using a mixture of economies of scale - buy concrete in bulk - and improvements to the 3D-printing machine, shutting the build time down to 12 and 24 hours.

這兩家公司的終極目標是大幅降低成本，利用大量購入混凝土的規模經濟同時改進3D打印機，令建造時間縮至12-24小時。

Although the focus for now is on those who need it most, the houses will not be a hand-out.

儘管目前該項目以最需要房屋的人羣爲重點，但公司不會免費供應這些房屋。

"The families agreed to a no-interest, no-profit mortgage that they will pay over about 10 years." according to Brett Hagler, who supervises the project. That works out to about $30 a month.

該項目負責人布萊特·哈格勒表示：“許多家庭同意以無利息、非盈利貸款的方式約分10年支付房款。”按此計算，其月供約爲30美元。

Later this year, the project will head to El Salvador to build some test homes, with the view to begin work on a community of 100 houses in 2019.

在今年晚些時候，這項計劃將在薩爾瓦多建造一些測試用房，目的是能在2019年開始建造100間3D打印房屋的社區。

"If it does work it could literally change how shelter is created," Hagler said.

哈格勒稱：“如果該項目能夠成功，將實實在在地改變避難所的建造方式。”
