SUNLU Silk Dual Color PLA+ 1.75mm

A smooth, shiny finish is often what makes a 3D print look intentional, and the SUNLU Silk Dual Color PLA Plus filament is built for that effect. This 1.75mm PLA+ option combines a silk like texture with a dual colour look that changes from angle to angle, so your models can show varied tones without switching materials. It’s a practical choice for creators who want a polished surface appearance and eye catching colour shift in everyday prints 🎨

Key features

SUNLU’s silk dual colour filament uses one spool to produce a dual colour effect, using a 360° visual reveal to show different colour combinations depending on how the print is viewed. That means your finished pieces can display varied shades without you having to plan separate colour passes. The filament also focuses on a smooth, silky surface texture, with vibrant tones designed to look glossy and clear straight off the print.

If you enjoy experimenting with display models, decorative parts, or colour expressive prototypes, this kind of dual colour behaviour can make your work stand out more quickly. The silk surface approach is designed to reduce the need for extra polishing, so the print can be moved from build plate to display with less finishing time. Keep in mind that results will depend on your printer settings and how your specific model is oriented, since the visual effect is tied to viewing angles.

A further point is the PLA+ formulation. According to the manufacturer, the silk PLA+ is described as having higher hardness compared with standard PLA, while also keeping flexibility properties so it does not snap easily. It also claims impact resistance and strong compression resistance, which can matter for functional decorative components that you still want to handle or fit into a setup without being overly fragile. ✨

What to know

To help keep print quality consistent, the filament is described as carefully wound on a machine for organised spools. That packaging approach is intended to support neat feeding and reduce tangles during printing. The product also includes reusable vacuum storage bags, which are designed to help protect the filament from moisture and keep it in better condition over time. The packaging mentions using double protection with desiccants, which is especially helpful if your workspace has variable humidity.

When you’re planning projects with dual colour silk materials, orientation can make a visible difference because the colour reveal is linked to angle. If you want the most dramatic effect, it can help to think about how the object will be viewed in real life, whether it will be framed, displayed on a shelf, or used as a decorative insert. You may also prefer this filament when you’re aiming for a shiny look that reads clearly under normal room lighting, rather than a more matte aesthetic.

It’s also worth noting the practical handling details, since they affect whether you can print reliably from the start. The stated diameter is 1.75mm with precision of +/- 0.02mm, and the spool is 1KG. That combination supports compatibility with common setups that expect 1.75mm PLA+ filament, while giving you a substantial quantity for longer runs. 🛠️

Who it’s for

It’s a good fit if you want a silk like PLA+ filament that produces a shiny surface and a dual colour effect that reveals varied tones as you move the print. It also makes sense if you prefer less finishing work, because the smooth appearance is designed to reduce the need for polishing. You’ll likely appreciate it most for decorative models, creative displays, and colour expressive prototypes where visual impact matters.

It may not suit you if you need a strictly uniform colour across every viewing angle, since the whole point is the angle dependent dual colour behaviour. It might also be a less convenient choice if you store filament without any sealed storage routine, because the product itself emphasises moisture protection. Still, for makers who plan their prints and store supplies carefully, this SUNLU filament offers a strong balance of visual finish, PLA+ toughness claims, and day to day usability.
