Is Manual Filament Tuning Still Worth It?

Hackaday reports on a perennial question among three-D printer enthusiasts: is manual filament tuning still worth doing? Modern consumer FDM printers offer automatic leveling, temperature regulation, and presets that satisfy casual users just fine. But according to a recent video by maker MandicReally, there's still a case for hands-on optimization. Testing showed that tuning settings like temperature, flow rate, retraction speed, and material shrinkage specifically to your printer's heating elements and nozzle can yield faster prints with better accuracy than generic presets. For hobby makers, auto-configuration is probably sufficient—but for production runs, that extra precision could mean real gains in speed and consistency.
