It's meant as a sort of satirical / funny image introducing to the question, as someone else pointed out because of the huge layer height.

I haven't bought anything yet, it's just a project for the future. The maximum nozzle diameter I found for the printer is 0.8mm. It's probably the maximum recommended nozzle diameter for the printer...

When asking GPT – as you say – it says you'll have to go under the diameter of your nozzle: "The maximum layer height is typically 75-80% of your nozzle diameter" That means I could print with a layer height of 0,64mm. Unfortunately I think that's still too small.

I'll have to check the performance of my printer and do additional research to tell how much my printer can extrude and if I can find or produce the right nozzle for my printer (maybe I can drill a hole with a larger diameter in the nozzle?).

Thank you!

That's cool. I now found a video of a 3mm nozzle in use: https://www.youtube.com/watch?v=NO1qNjNkl-E It really has a special look. Unfortunately I don't think it will be compatible with my printer.
