Is it worth playing with the Print Speed, Travel Speed, Bottom Layer Speed, Infill Speed, Top/Bottom Speed, Outer Shell Speed, or Inner Shell Speed? Any one of these more helpful than others?
Are the Cura defaults already pushing the limit? Or does it pay to tweak?
If you’re printing mechanical parts, try going to a bigger nozzle. The jump from .35 with a .2 layer height to a .5 nozzle with .3 layer height seriously lowered print time.
