This 3D-printed, carbon-absorbing bridge is inspired by bones

The concrete and cement sector has been trying to reduce its environmental impact for years through sustainable concrete mixtures or efficient designs.

Now, a research team at the University of Pennsylvania has combined both novel materials and a material-saving design, without compromising on strength and durability.

The project, called Diamanti, takes inspiration from nature and uses a robotic 3D printer to create complex, lattice-like patterns with a sustainable concrete mixture.

While most regular concrete absorbs carbon dioxide (up to 30% of its production emissions over its entire life cycle, according to some research), Diamanti’s enhanced concrete mixture absorbs 142% more carbon dioxide than conventional concrete mixes.

Its first design, a pedestrian bridge, uses 60% less material while retaining mechanical strength, says Masoud Akbarzadeh, an associate professor of architecture at the University of Pennsylvania and director of the lab that spearheaded the project.
