Argentinian manufacturer Trideo makes a 3D printer so large, it comes on wheels.
The gigantic Big T has a build area of one meter square, making it large enough to print automobile rims, manufacturing jigs, foundry models for creating sandcasting molds of enormous parts, expansive cityscape models, a larger-than-life bust of Diego Maradona and more.
The huge build area would take forever to fill with a run-of-the-mill nozzle, so Trideo's developed the Typhoon, a high-flow nozzle "designed to extrude 2.85mm filament with a flow of up to 200mm³/s, almost 1kg/h," they write.
Here's a timelapse of the Big T printing a gigantic castle:

It's worth noting that even with the Typhoon nozzle, that thing took ten days to print.
