This silk filament is really nice! The tricolor blend of blue, black, and purple creates a magical, color-shifting effect that looks incredible from different angles. My husband uses a Bambu X1 3D printer and this filament runs nicely with it. The diameter is consistent, runs smooth without clogging or tangles. The silk finish gives prints a glossy, polished look, making them stand out beautifully. It adheres well to the print bed and prints with strong layer bonding; while silk filament can sometimes be a bit more brittle than regular PLA, this one maintains a good balance of strength and flexibility.
