What makes marble PLA different from standard PLA?
Marble PLA is a PLA base with a swirl pigment compounded into the strand, so light and darker veins appear inside the same filament. One extruder and one spool are all that is needed - no blending unit, no painting step. It prints with the normal PLA routine and asks nothing extra from the machine; the visual effect is a surface result, so it does not add mechanical strength.
