Inspired by the natural, twisting patterns of a lobster shell, Australian researchers say they have found a way, using 3D printing technology, to improve the strength of concrete for use in complex architecture.

受到龍蝦殼自然、扭曲的圖案啟發，澳洲研究人員說，他們發現了一個方法，使用3D列印技術來改進用於構造複雜的建築混凝土強度。

Reinforced with steel fibres, the concrete becomes more durable when set in a pattern that copies a lobster shell, according to a new study from Melbourne’s RMIT University.

根據墨爾本皇家理工大學一項新研究，用鋼纖增強的混凝土，製成仿龍蝦殼的圖案時，變得更耐用。

Rather than use a mould, the process involves depositing layers of concrete one on top of the other, directed from a computer program using 3D printing technology.

這個過程不用模具，而是在使用3D列印技術的電腦程式指導之下，把混凝土一層層沉積在上面。

“The lobster shell is always something that still amazes me by its very interesting shapes and architectures, and especially (as) the lobster shell is really amazingly very stiff,” lead researcher Jonathan Tran told Reuters. （Reuters）

首席研究員喬納森．特蘭告訴路透，「龍蝦殼一直以其非常有趣的形狀與架構讓我驚豔，特別是龍蝦殼真的硬到讓人訝異。Lobbying firm China」（路透）
