Stop blaming your 3D printer for slow prints, your slicer settings are sabotaging you

Slow 3D prints are often caused by poorly tuned slicer profiles rather than hardware limitations. Overbuilt settings like excessive wall count, high infill percentages, fine layer heights, and too many top/bottom layers add significant print time without meaningful benefit for most everyday parts. Adjusting these settings — such as dropping infill from 25% to 10% or reducing wall count — can dramatically cut print times. While hardware ceilings do exist, most users leave time on the table by never questioning default or overly cautious slicer profiles. Optimizing the slicer profile should come before considering hardware upgrades.
