3D Printing helps bring the underground Crossrail to London

Crossrail, a £14.8 billion project to expand London’s underground train network, is using 3D printing in the construction of its tunnels.

Competing alongside leading contractors including SKANSKA, BAM Nuttall and Balfour Beatty Civil Engineering, UK privately owned construction company Laing O’Rourke is using the technology to get the edge on tunnel building.

Europe’s largest construction project 

Spanning over 100km, and connecting 40 stations from east to west, Crossrail is the largest construction project in Europe. The new tunnel under construction is named The Elizabeth Line after the reigning Queen Elizabeth II.
