SUNLU Silk Dual Color PLA+ 1.75mm 1kg spool 🎨

This dual-colour silk PLA+ filament gives prints a glossy, shimmering finish that changes with the viewing angle, making it a good choice for decorative models, cosplay parts and display pieces. The SUNLU Silk Dual Color PLA Plus spool combines a black-to-purple silk effect with 360° colour shifts and a smooth surface, helping printed objects look polished without post-processing.

Key Points

The filament is made to offer a two-tone appearance in a single extrusion, so models show different hues when rotated or viewed from different directions. According to the manufacturer the PLA+ formula improves toughness and reduces brittle failures compared with standard PLA, which can be useful where parts need some impact resistance or slight flexibility. It is supplied on a neatly wound 1kg (2.2lbs) spool and vacuum packed with a desiccant to limit moisture and prevent bubbles during storage.

Practical Tips

Feed settings that favour steady extrusion help reveal the dual-colour effect more consistently. A nozzle temperature within the recommended range tends to produce glossy layers and good interlayer adhesion, while faster print speeds may reduce the sheen so adjust speed between 50 and 100 mm/s depending on the model complexity. For larger flat surfaces, a slower speed and modest cooling can reduce banding and enhance the silk finish.

Consider drying the filament before longer prints if it has been exposed to humid conditions, even though the spool arrives vacuum sealed. Small ornamental parts and visual prototypes benefit most from the silk texture, while functional parts that need high heat resistance may be better printed in a specialised engineering filament.

Advantages

The silk PLA+ eliminates much of the need for sanding or polishing when the aim is an attractive surface, and its smoother feel highlights fine details and contours. Winding quality is emphasised to reduce the risk of tangles and feeding interruptions during long prints. Compatibility with a wide range of FDM printers is noted for the 1.75 mm size, making it straightforward to integrate into common desktop setups.

A minor limitation to bear in mind is that the silk surface can make layer lines more visible in some lighting, and the dual-colour effect depends on part geometry and viewing angle rather than producing uniform colour gradients. For pieces intended mainly for mechanical load or high-temperature environments, check material properties against the project requirements according to the manufacturer.
