Start with a standard PLA profile: extruder 200–220 °C, bed 50–60 °C.
Moderate print speed (40–60 mm/s) keeps transition zones clean and visually distinct.
Enable cooling for sharper transitions and better surface finish.
Because each spool has transitioning colours, aim to print pieces large enough to show those changes — small parts may stay mostly one shade.
For best visual effect, orient geometry so the gradient runs along visible surfaces or layers rather than hidden zones.
