Silk Rainbow PLA Filament 1.75mm 4-Pack - Shiny Color Changing Set

In this review of the Silk Rainbow PLA Filament 1.75mm 4-Pack, the bottom line is simple: this kit is best for hobbyists and crafters who want glossy, multicolor prints without managing multiple spools. The set includes four 250g spools in distinct series (candy, forest, yellow and blue), and its standout feature is the fast color changing silk PLA that shifts roughly every 10m-12m, producing smooth, shiny gradients across larger prints. The review focuses on real-world printing behavior, ease of use, and how reliably the filament delivers the promised glossy finish.

Key Features

• 4-Color 1kg Pack: Four 250g spools provide a variety of silk color options so a single purchase covers multiple projects without swapping filaments constantly.
• Fast Color Changes: Color shifts every 10m-12m make the filament ideal for larger objects where visible multicolor gradients are desired.
• Silky Gloss Finish: The upgraded PLA raw material yields a glossy, smooth surface that highlights curves and detail in decorative prints.
• Vacuum Sealed and Dried: Each spool is dried 24 hours and vacuum packed with desiccant, reducing moisture-related bubbles and improving extrusion stability.
• Tight Diameter Control: CCD measurement and adaptive control keep the diameter within +/-0.02 mm for consistent layer bonding and better bridging.
• Wide Compatibility: Works with most 1.75mm FDM printers and prints well in the recommended 190C-230C nozzle range and 50C-60C bed range.

Who It's For

This pack is aimed at makers, artists, and beginners who want eye-catching, multicolor finishes without changing spools while printing larger models. The silk surface suits decorative items, props, and display pieces where surface sheen and color flow are priorities.

Those who need exact, frequent color stops or very small, highly detailed mechanical parts may want a filament with deliberate, shorter color segments or a single-color engineering filament. Users with printers that have persistent adhesion or feeding issues should test a single spool first, since experiences with adhesion and clogging can vary by machine.

Pros & Cons

Pros

• Attractive glossy finish gives prints a polished, professional look without post-processing.
• Four distinct silk colors in one kit offer creative variety for scene building and multi-object runs.
• Vacuum packaging and drying reduce moisture-related printing problems and bubbles.
• Consistent diameter tolerance improves layer adhesion and print stability across long prints.

Cons

• Color variation and the gradual color transition are mixed among users, so exact color placement is not guaranteed.
• Some printers report adhesion or rare feeding issues, so calibration and test prints are advisable before a long run.

Our Verdict

The Silk Rainbow PLA Filament 1.75mm 4-Pack is a good value for makers who prioritize surface sheen and colorful gradients in decorative prints. It combines vacuum-sealed spools, reliable diameter control, and striking silk finishes to produce attractive results; just allow for some variability in exact color changes and verify printer setup for adhesion before long prints.

Frequently Asked Questions

Will this filament work with my 1.75mm FDM printer?
Yes; the filament is designed for most 1.75mm FDM printers and prints well in the recommended 190C-230C nozzle range.

How quickly does the color change along the filament?
Color shifts occur roughly every 10m-12m, which creates smooth gradients best seen on larger prints.

Do the spools arrive ready to print?
Yes; each spool is dried for 24 hours and vacuum sealed with desiccant to reduce moisture and bubbles.
