Speed is good, but there is a practical limit to how fast we can
print. Not sure what it is, but I doubt that the plastic will properly
bond at 2M/sec.

There isn't a minimum speed per se, but for some things, such as
bridging voids, printing faster yields noticeably better results. I
would say the minimum speed for good results is somewhere around
30-35mm/sec, and depending on your printer you can get good results up
to 200+mm/sec, possibly much faster.

The reason to go fast for hobby stuff is sanity. ;-) Imagine you were
milling a large void in an object, but you could only do it at .35mm
DOC and .5mm width... You can imagine that it would be a pretty
frustrating experience, even with CNC. Printing is the same way. You
don't have to print faster, but it certainly makes the process more
fun.
