Tri-Colour Silk PLA 1.75mm 1kg | AMS Ready

Dynamic Colour for Every Angle

Triple the Colour, Triple the Impact with Tri-Colour Silk PLA

We are proud to offer 5 bold tri colour silk combinations, where three tones are co extruded into a single strand to create a shifting, high gloss finish. As the print moves, so does the colour, revealing new tones and transitions from every angle. With a silky surface, rich pigmentation, and effortless visual depth, each shade is designed to bring your prints to life without the need for multi material setups.

Triple Colour, Single Feed

Smooth Multi Colour Printing, No Extra Setup

Tri Colour Silk PLA is fully compatible with Bambu Lab AMS systems, allowing you to enjoy seamless multi colour printing without the need for manual filament changes. Because the three colours are co extruded within a single strand, you get dynamic colour shifting effects while using just one AMS slot, making it both efficient and visually impactful.

With reliable feeding, low warping, and consistent extrusion, Tri Colour Silk PLA delivers vibrant, high gloss results effortlessly across a wide range of AMS enabled setups.

Built for Visual Impact

Tripple Colour, One Continuous Feed

Three distinct colours are co extruded side by side within a single strand, creating a seamless tri colour effect throughout your print.
Unlike gradient filaments that shift over length, this structure delivers consistent colour variation across every layer, allowing each surface to reveal a different tone depending on orientation.
The result is a dynamic, multidimensional finish that adds depth and visual interest without any extra setup.

Silk Finish That Stands Out

Formulated for a smooth, high gloss surface, Tri Colour Silk PLA produces a silky, reflective finish straight off the build plate.
Light interacts with each colour differently, enhancing the shifting effect and giving prints a premium, almost metallic appearance.
This makes it ideal for decorative models, display pieces, and any design where visual impact matters just as much as form.

Easy Printing, Consistent Results

Built on a PLA base, Tri Colour Silk PLA remains easy to print with low warping, minimal odour, and reliable layer adhesion.
It feeds smoothly through most standard 3D printers and performs consistently across a wide range of settings, making it accessible for both beginners and experienced makers.
With strong print reliability and striking results, it’s a simple way to elevate your prints without adding complexity.

Understanding Tri-Colour Silk PLA at a Glance

Tri Colour Silk PLA is designed with visual impact in mind, prioritising finish and ease of use over mechanical strength.
It scores highly in ease of printing thanks to its PLA base, offering low warping and consistent, reliable results across a wide range of printers.
Durability and strength sit at a moderate level, making it suitable for decorative and light functional prints rather than high load applications.
With low heat resistance and moderate flexibility, it performs best in indoor environments where aesthetics are the priority.
Overall, it’s a well balanced filament for creating bold, high gloss prints with minimal effort.
