Add a flash point on the transparent PLA filament to make the filament look bright. Different color filaments add different color flash points to get more color experience. We have six different colors, two sizes, one kilogram and 250 gram suits. 1kg single roll package, 250g * 4-roll package. It can be customized according to customers' preferences. Because the filament contains flash point, it is recommended to set the printing layer height to 0.3mm in the parameter setting during printing, which greatly improves the success rate of printing.
