The 2 robots labored collectively, the primary making use of a layer of concrete and the second including a ring-shaped reinforcement each 20 centimetres. This permits the weather to behave as a shell and to bear hundreds.
The novel concrete combination included two components added simply earlier than it left the pressurised nozzle, making a droplet-like aid on the columns.
The tower took 5 months to print on the college’s Hönggerberg campus.
The elements had been assembled within the close by village of Savognin after which delivered to Mulegns for meeting.

The design was impressed by native confectionery: an ornate layered cake distinctive to the area. It additionally references Baroque builders in Switzerland’s Grisons area.
