SUNLU PLA Filament Rainbow 1.75mm 1kg 3D Printer Filament

The SUNLU PLA Filament (Rainbow) 03 is a high-quality 3D printer filament that delivers vibrant multi-color gradient effects. Made from pure polylactic acid (PLA), this filament is biodegradable, odorless, and easy to print, making it ideal for both beginners and professionals. With a diameter of 1.75 mm and a net weight of 1 kg, it offers consistent extrusion and excellent layer adhesion.

Advantages

This rainbow PLA filament produces stunning color transitions without needing multiple extruders. It is 100% bubble-free, ensuring smooth prints with minimal clogging. The vacuum-sealed packaging with desiccant keeps the filament dry and ready to use. SUNLU's strict quality control guarantees a diameter tolerance of ±0.02 mm for reliable performance.
