By , SYDNEY (Reuters) - 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.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.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.“The lobster shell is...…By , SYDNEY (Reuters) - 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.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.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.“The lobster shell is...WW…
