A quick question for 3d printing experts, when people say for instance the print speed was 50 millimeters a second, do they mean travel speed? 
No. That’s the fastest printing speed. So things like the inner walls and support material. Travel speeds are like 90-150mm/s as just moving doesn’t need to be accurate and faster speeds keep plastic from oozing out during a move.
I keep the infill speed at 40mm a second and first layer at 20 millimeters a second and the travel stays at 150 millimeters a second. Oh retraction at 1 millimeter, this was the result.

ugh, @Ailsa_Steven , nobody wants your garbage spam.
@Ailsa_Steven oh Alisa, you’re so hot that it makes me want to buy all your stuff. Please post more of it…
@Tom_L @Kevin_Danger_Powers sorry but you won’t be seeing her around here anymore 
@Griffin_Paquette welp, that was short lived. Lol.
I think thats the speed the extruder moves at when printing. Not how much filament yout spewing out per second. Because that would be ridiculous lol. Thou when printing with a .8mm nozzle at 1.2mm extrusion width 40mm/s is just about how fast that filament is being used up lol
And to answer the question: print speed refers to the speed with which the head moves as it is extruding plastic. Travel speed is a separate value.
Something to be aware of however:
Not all (in fact I don’t think any) machines print at their specified print speed all the time. In the machine’s firmware, acceleration and jerk values are configured to prevent the printer going from 0 to full velocity immediately. Because of this, the printer is constantly accelerating and decelerating.
