This 1kg spool of SUNLU Silk PLA+ red copper filament is a type of polylactic acid (PLA/PLA+) filament that has a slight sheen or luster, reminiscent of silk fabric. It can be distinguished from glossy and matte PLAs by having an intermediate level of reflectiveness.
This Silk PLA is formulated with additives that provide a subtle sheen without appearing overly glossy. The additives create the characteristic silk-like shimmer. For printing silk PLA+, the print temperature of it is little high than normal PLA.
