It’s 1.75mm filament going into 2mm layers. lol, wtf. Still looks great, though.
Extrusion is a mix of temperature, feed rate, speed and pressure.
Basically the hotend temp could be high enough that the plastic melts but it still “pushes” just fast enough to build pressure to drive it. Not too much, otherwise the filament grinds and extruder skips, but at the right amount you can keep up with the feed.
The nozzle, lifted up a bit, moves slow enough that the filament comes out and spreads out from the pressure pushing on it. Making the line wide and tall.
The dance is keeping those in sync. Move too fast and the lines are thin, too slow and they’re too wide.
Nozzle too high and it doesn’t blend into the layer below as much as sit on top. Too low and the extra pressure pushes the filament around and it curls back up onto the nozzle.
