Yes. I had involvement in multiple-storey projects as well. The maximum that we accomplished here in Canada was in Kingston, Ontario. It was a three-storey building. We printed the basement, the main floor and part of the second floor.
The technology right now.... There are a few printers available, and we have two different printers. One of them is able to print up to three storeys without needing to move the printer up. With just one position, you can print three storeys.
The other printer is a bit more flexible. We can print multiple storeys by moving the printer up. It's a very light printer. It's 2,500 kilograms. With a small crane, you can bring the printer to the next floor.
