SUNLU Silk PLA+ Triple Colour 4kg filament

SUNLU Silk PLA+ Triple Colour filament is a silk-textured 3D printing material designed to give a distinctive shiny finish and a colour-changing look as your model rotates. With a 360° spin effect, the same filament can show varied colour combinations depending on angle, which makes it a popular choice for decorative prints and eye-catching prototypes. If you want a smoother surface appearance without extra sanding, this triple colour PLA+ option is built to help you get there in fewer steps.

The essentials

If you like prints that look polished straight off the bed, SUNLU 4KG Silk Triple Color PLA+ Filament is made for that visual impact. It uses a silk-like texture that produces a glossy, shiny surface appearance, so your finished parts can stand out even without heavy finishing work. The triple colour PLA+ design is also intended to reveal different colour tones as the model is viewed from different directions, adding depth to lettering, figures, and display pieces. 😊

This is also a practical choice for everyday FDM printing because it aims to feed smoothly and consistently. The filament is described as having minimal tolerance and low deformation, so it can help reduce feeding issues that lead to interrupted prints. There is a specific focus on avoiding nozzle blockages and extrusion problems, which matters when you are working on longer sessions or detailed models. The result is a filament that is intended to be straightforward to run, not a constant troubleshooting project.

A further point to keep in mind is that PLA materials are generally sensitive to temperature and build settings, so you will get the best outcomes when you follow the recommended nozzle and bed temperatures provided by the manufacturer. That way, the silk surface effect and print quality are more likely to match what you are expecting. 🙂

Key features

What you’ll notice most is the silk texture and the shiny appearance it delivers. The filament is described as smooth and silk-like, with vibrant and colourful tones designed to create a dazzling surface without the need for polishing. That makes it well suited to models where appearance matters, such as ornaments, cosplay accents, stand-out prototypes, and presentation-friendly parts. ✨

The triple colour aspect is built around a 360° spin reveal effect. In practical terms, the same printed piece can look like it has multiple colour combinations when viewed from different angles, rather than a single flat colour. This is a useful way to add visual interest without changing filament during the job. It is especially effective on curved shapes, spirals, layered designs, and anything that benefits from viewing from multiple sides.

It is also positioned as a PLA+ formulation with higher hardness than standard PLA, with the manufacturer stating it is 50 times harder. At the same time, the material is described as maintaining flexibility without snapping easily, which can be helpful for parts that need a bit of resilience. The packaging and handling details are meant to support consistent printing as well, including vacuum sealing and the inclusion of a desiccant pack to help protect the filament from moisture.

For printing convenience, the filament feed is described as smooth and consistent, designed to avoid blocking the nozzle or causing extrusion problems. The manufacturer also includes guidance on recommended temperatures and print speeds, plus notes about low shrinkage and good layer adhesion. If you are already running an FDM printer in the typical PLA+ range, these parameters give you a clear starting point for setting up profiles. 🤝

Tech specs

What’s included

The bundle includes four packs of SUNLU silk PLA+ triple colour filament, with a total stated capacity of 4KG. Each spool is listed as a 1KG reusable spool, which can be convenient for storage and handling between prints. The filament is vacuum sealed with a desiccant pack, which is intended to help protect against dust and moisture before you load the roll. There is also guidance on spool dimensions for 1KG reels, which can be helpful if your printer has a specific mounting setup.

Compatibility is described for 1.75 mm filament with most FDM 3D printers, and the reel size is presented as suitable for many FDM systems that support that spool format. The manufacturer also references a filament length figure per spool, stated as 330 m per 1KG spool, which can help you estimate how much material you might need for a job. If you print frequently and want consistent silk results across multiple sessions, a multi-pack bundle like this can be a straightforward way to plan ahead.

It suits you if

You’ll like this filament if you want a silk shiny finish and a triple colour look that changes as you view your print from different angles. It makes sense if you are producing decorative models, display items, or creative prototypes where the surface appearance matters as much as structural function. It may not suit you if your projects require a fully matte finish or if you prefer a simple single-colour filament with no visual angle effect. Worth considering if you want an easy-running PLA+ filament and are happy to follow the recommended temperature and speed guidance for best results.
