Boat building is a long-winded and tedious business, even when what is going down the slipway is a small craft made from modern materials such as fibreglass, rather than something nailed together out of planks of wood. Construct a mould. Build up layers of resin and glass fibre inside that mould. Extract the completed structure and finish it. All told, it can take months.
That, though, may soon change. For researchers at the University of Maine are now in the process of testing an 8-metre (25-foot) patrol boat that took just 72 hours to make from scratch. Their trick was to build the vessel using a giant 3d printer. Since they appeared in commercial form in the 1990s, 3d printers have generally been employed in factories to make small things like prototype models, components of jet-engines and dental crowns.
To print the patrol boat, part of an American army project, the team in Maine linked up with Oak Ridge National Laboratory, in Tennessee, which helped develop the printing process, and Ingersoll Machine Tools, in Illinois, which built the printer itself. The university reckons that for boat building, a common trade in the state, large 3d printers of this sort will dramatically cut the cost and time required to produce new vessels.

造船是一項冗長乏味的工作，即使是用現代材料如玻璃纖維制成的小船，而不是用木板釘在一起的木船。構造一個模具，在模具內部堆積樹脂和玻璃纖維層，提取完成的結構并完成它?？偟膩碚f，這可能需要幾個月的時間。
不過，這種情況可能很快就會改變。緬因大學的研究人員目前正在測試一艘8米(25英尺)長的巡邏艇，這艘巡邏艇從無到有只用了72個小時。他們的訣竅是用一個巨大的3D打印機來建造這艘船。自20世紀90年代3D打印機以商業形式出現以來，它通常被工廠用來制造小物件，比如原型模型、噴氣發動機組件和牙冠。
為了打印巡邏艇，這是美軍項目的一部分，緬因州的團隊與田納西州的橡樹嶺國家實驗室進行了合作。橡樹嶺國家實驗室幫助開發打印過程，伊利諾斯州的英格索爾機床公司自己制造打印機。該大學認為，對于造船這一該州常見的行業而言，這種大型3D打印機將大幅削減制造新船的成本和時間。
