How does the veined effect work, and does the pattern repeat exactly?
The veining comes from pigments and surface behaviour inside the PLA strand, so the marble pattern is printed with the part and runs through the surface rather than sitting on top as a coating or a film. The material is PLA plastic, not stone, ceramic or a mineral-filled composite. Because the pattern comes from the strand, the veining falls differently on every part, so two vases from the same spool are never identical.
