ERYONE GUS-M4 Silk Tri-Colour PLA Filament, 1.75 mm, Red Blue Green, 1 kg

If you’re choosing filament for a clean, understated finish, standard PLA may suit the project, if colour and surface sheen are part of the design, ERYONE Silk Tri-Colour PLA brings both into the print itself. Its co-extruded red, blue and green strands create a distinctive multicolour effect. The silk surface adds a pearlescent shine, so decorative pieces can look finished without extra polishing.

Best use cases

Use this filament for display pieces, decorative models and other prints where colour and appearance matter alongside the shape. The three-colour effect can make a model more visually distinctive without adding a separate finishing step. Because the different colours can appear on opposite sides of a print, it’s a useful choice when a piece will be viewed from more than one angle.

For a practical project, consider a desk ornament or a small display model: the co-extruded colours and glossy surface give the finished object visual interest straight from the printer. It’s also suitable for 3D printing pens that accept 1.75 mm filament, offering a colourful material for hands-on projects.

Benefits

The silk finish gives prints a smooth, shiny appearance, while the red, blue and green combination creates variation within the same filament. This is a different design approach from choosing a single-colour filament and adding colour later: here, the colour effect is part of the material and the printed result. The PLA formulation is described as having strong layer adhesion, and the controlled 1.75 mm diameter is intended to support consistent feeding.

Buyers often highlight the vivid colour and shine, and some say the filament prints smoothly and produces pleasing results. Feedback is mixed on adhesion and smoothness, while some buyers report brittleness. These experiences are useful context when choosing a silk PLA for a particular project, the documented draw is its multicolour, pearlescent finish.

Worth noting

This is co-extruded silk PLA with a red, blue and green colour combination, supplied as 1 kg of filament on a cardboard spool. Its stated diameter is 1.75 mm, with a tolerance of +/- 0.03 mm. ERYONE describes it as compatible with 99% of FDM 3D printers and 3D pens. Match the 1.75 mm filament size to the equipment you plan to use.

As with other silk-effect materials, the surface appearance is a central part of the choice: it’s suited to prints where a glossy, colourful finish is welcome, rather than projects whose priority is a uniform, plain-colour look. The stated material is polylactic acid (PLA).

Questions before you buy

Which colours are in this filament? It combines red, blue and green in a tri-colour co-extruded filament. The colour effect can vary across the printed piece, with different colours appearing on opposite sides.

What filament size does it use? The diameter is 1.75 mm, with a stated tolerance of +/- 0.03 mm. Check that your printer or 3D pen accepts this filament size before loading it.

What kind of finish does it produce? It is designed for a shiny, pearlescent silk look. ERYONE says the finish does not require extra polishing, making it a practical option for decorative prints where the surface appearance is part of the design.

When it makes sense

Choose ERYONE GUS-M4 when you want a PLA filament to contribute colour and shine as the print takes shape, rather than relying on a plain finish or adding colour afterwards. Its 1 kg spool, 1.75 mm diameter and red-blue-green silk effect make it a considered fit for decorative models and display pieces printed on compatible FDM equipment.
