What gives the stone texture, and what actually makes this filament consistent?
The stone look comes from pigments and a matte surface effect inside the PLA strand, so the veined texture prints with the part instead of sitting on it as a coating; the material remains PLA plastic, not stone or ceramic. Consistency comes from batch control: colours are run as separate controlled batches on one line, and the dimension is held on a 1.75mm round profile, so tone and printing behaviour stay in family between spools.
