SUNLU Silk PLA+ Rainbow 04 filament 1.75mm FDM PLA R 04

SUNLU Silk PLA+ Rainbow 04 is a 1.75 mm PLA filament for FDM 3D printers. The spool holds 1000 g of material, with a length of about 330 metres. The filament follows a rainbow colour sequence that shifts roughly every 8 metres, so printed objects show smooth colour transitions and a multicoloured look.

The material is designed for consistent extrusion, with a dimensional tolerance of ±0.02 mm and low shrinkage. According to the manufacturer, this supports stable print results and helps reduce problems such as clogging or air bubbles. The filament is stated to work with many common FDM printers, including models from Bambu Lab, Creality, Prusa and Anycubic.

It suits decorative pieces, toys and creative models where colour effect and fine detail matter.
