Why are there two choices for black?
All 3D prints are made from the same raw Nylon materials. Black Natural Versatile Plastic is a print that comes straight out of the printer, cleaned and then is simply placed in a dye bath. Black Natural Versatile Plastic is not polished or surface finished in any manner. The result is a grainy/fuzzy surface texture. Professional plastic starts with colored raw material (either Gray and Black) resulting in more even and saturated color. Professional Plastic uses a newer process that results in a smooth semi-gloss finish. Professionsl Plastic is also produces a stronger print.
