It’s 1.75mm filament going into 2mm layers. lol, wtf. Still looks great, though.
Interesting comparison with water gun, but that would be equivalent of extruding in the air (even then I see it possible if the nozzle is not way too big). Think about connecting water pipe to a bigger diameter pipe. Water would fill the whole volume and it would just move slower if flow is laminar. There is also filament infront of the nozzle while printing so that should provide resistance (plus friction in the nozzle) to allow pressure build up. Nozzle shape might be important here, but I guess they just drilled 2.4 mm hole all the way through.
I obviously don’t know much about this nozzle, I’m not trying to teach anyone, I’m just having fun brainstorming and hopefully learning something new

Exactly what I’m doing! Haha.
My problem with the “water into a larger diameter pipe” idea is that, while the filament is melted, it isn’t a free flowing liquid that expands quickly to fill it’s container; I’m trying to picture the balancing act that would be required to get the filament to expand by pushing against the build plate/ previous nozzle, but I can only see it ending in a nasty clog.
You’re probably right and it’s likely much more simple than I’m making it out to be. I still like my idea of a baffled nozzle, though. Haha
