SUNLU 3D Printer Filament Bundle, Silk Filament Multicolor, Individually Vacuum Packed, Dual Color*5, Triple Color *3, 2kg in Total

I picked up this 4-kilogram SUNLU Silk PLA filament bundle (Silver, Light Gold, Silk Dual Color Red-Gold, and Silk Triple Color Blue-Green-Purple) to execute a large-scale run of display models, artistic sculptures, and detailed cosmetic containers. Aesthetic filaments can often be a gamble because the chemical additives used to generate the high-gloss shine can compromise structural layer bonding. This collection completely hit the mark, delivering pristine manufacturing quality and breathtaking metallic brilliance across all four specialized spools. Why this multi-format silk bundle is an absolute masterpiece: Spectacular Mirror-Like Sheen: The surface reflection on the solid Silver and Light Gold spools is phenomenal. The gold looks deeply rich and metallic, while the silver mimics a polished aluminum look, doing an incredible job of naturally diffusing light to mask layer lines completely. Flawless Coextrusion Trajectories: The Dual Color (Red-Gold) and Triple Color (Blue-Green-Purple) spools are beautifully manufactured. The distinct color strands are split evenly down the cross-section of the 1.75mm line without twisting. This ensures that as the model prints, the colors shift dynamically depending on the angle you view it from, giving parts a jaw-dropping iridescent finish. Impeccable ±0.02mm Dimensional Control: I measured the line diameter at multiple random points across the roll using digital calipers, and it stayed highly consistent. This precise uniformity completely prevents under-extrusion gaps or sudden over-extrusion z-banding on flat surfaces. Neat Tangle-Free Spool Winding: The mechanical layering is tight and orderly from the inner core to the outer rim. It unspools seamlessly into the feed lines with zero overlapping loops, which completely eliminates the risk of mid-print tension snags ruining an unattended overnight run. Makerspace Setup & Printing Calibration Tips: Bump Up the Heat for Maximum Shine: Silk PLA requires a bit more thermal energy to unlock its full gloss potential. If you print it too cold, it will turn out dull and matte. I found the sweet spot for a flawless, high-shine finish was running a 220°C nozzle temperature, which is roughly 10°C hotter than my standard PLA profile. Keep Cooling High for Crisp Overhangs: Because silk blends tend to retain heat slightly longer than standard raw PLA, ensure your part cooling fans are running at 100% to keep sharp geometries and overhanging structures crisp and warp-free. My Settings: Achieved flawless results running a 220°C nozzle temperature, a 55°C bed temperature on a smooth plate, and a conservative printing speed of 60–100 mm/s to ensure the best possible surface reflection. Is it worth it? SUNLU has delivered a spectacular variety bundle that offers a massive amount of premium visual flair for an unbeatable bulk price point. It flows reliably, handles complex geometric patterns cleanly, and provides unique color transitions that make every model exciting to watch on the build plate. It is an absolute home run for any maker looking to elevate the overall visual quality of their cosmetic models.

I've really enjoyed using this filament. The filament prints beautifully with a smooth, shiny silk finish and excellent layer consistency. The dual-color effect looks great on finished prints and makes details stand out. I also had no issues with bed adhesion or clogging during printing. My only criticism is that the product photos are a little misleading. I expected the filament to lean more pink based on the pictures, but in person the colors are definitely more orange-toned than anticipated. The color is still lovely, just different from what I expected when ordering. Overall, this is a high-quality filament that produces gorgeous prints, and I would absolutely buy it again!

The SUNLU Shiny Silk PLA 4-pack delivers excellent color quality and prints beautiful trophies, making it a reliable choice for awards and multi-color projects. These colors look absolutely great! I bought this 4-pack specifically to print out 1st, 2nd, and 3rd place trophies. The gold, silver, and copper filaments are perfect for the podium spots, and the trophies turned out looking amazing. I did not need the weathered bronze for this specific project, but it looks like a nice color and I will definitely find a use for it eventually. The prints came out clean and shiny, and I cannot wait to hand them out on awards day. Another solid product from SUNLU!

I’ve used a lot of PLA+ over the years, and SUNLU’s Silk Four‑Color PLA+ (1.75mm) is one of the more impressive specialty filaments I’ve tested. It delivers the eye‑catching shine you expect from silk PLA, but with better consistency and fewer print headaches than many other multi‑color blends. Print Quality: The finish is gorgeous — smooth, glossy, and reflective without looking overly artificial. The color transitions are clean and gradual, which makes decorative prints, vases, and display pieces look premium right off the bed. Layer lines are noticeably minimized thanks to the silk formulation. Performance & Reliability: SUNLU advertises ±0.02mm dimensional accuracy, and it shows. Filament diameter is consistent, extrusion is smooth, and I didn’t experience any clogging or under‑extrusion on a Prusa MK4 or an Ender‑3. Bed adhesion was solid at standard PLA temps, and warping was basically nonexistent. Color & Aesthetic: The four‑color blend is the real star. Depending on the model orientation, you get beautiful gradients or bold color shifts. It’s perfect for artistic prints, gifts, and anything meant to stand out on a shelf. What I Liked: Beautiful silk shine with rich, vibrant color transitions Very consistent extrusion and dimensional accuracy Great for decorative and display‑grade prints Minimal stringing compared to other silk filaments What Could Be Better: Not ideal for functional parts (typical of silk PLA) Color transitions vary depending on spool section — not a flaw, just something to plan for Bottom Line: If you want a filament that prints reliably and looks stunning right off the printer, SUNLU’s Silk PLA+ is a fantastic choice. It’s one of the easiest silk blends I’ve worked with, and the four‑color gradient adds a premium look to any project.

I was very impressed with the print quality of this filament. It prints consistently, produces clean, detailed results, and has worked flawlessly in my Creality printers. I haven't experienced any clogging issues, and it's very reasonably priced for the quality you get. The silk PLA finish has an outstanding shine that really makes finished prints stand out, giving them a smooth, premium appearance. I would definitely purchase it again and recommend it to anyone looking for reliable, high-quality filament.

Love the multicolor filament. Prints out beautifully. Nice to use in single color machines to give your products some oomph! Definitely will buy again.

Filament printed just fine out of my bamboo x1c. Colors aren't quite as vibrant as the picture makes out and we're definitely matte. Other than that, good quality filament with a much quicker color change than some of the other gradated filament I've used.

This filament is a great option. At $45 (purchased on sale) for 4 spools you can’t beat the price. It prints consistently and looks very visually appealing with the color changes in it. I had no issues with my machine or clogging (bambu printer).

Love this filament. Works great in my Bambu A1 printer. Colour is more rainbow than what is pictured.

Bellissimo colore… si stampa bene ed ha un ottima finitura

Kanonfina utskrifter! Kul med färgskiftningar och blank yta. Skriver man ut en kub så kan man få olika färger på olika sidor. Modeller med mjukare former (som ödlorna i bilden och filmen nedan) har inte lika tydliga gränser. Där blir övergångarna mjukare. Har fått några misslyckade utskrifter, men inte värre än andra fabrikat. Notera att det krävs lite mer värme en vanlig PLA.

Me gusta esta marca por que el color me parece bonito y trabaja bien, casi no he tenido problemas con este filamento

Me gustó mucho la calidad, tiene buen brillo una vez la pieza impresa, he probado otras marcas y esta resultó de las mejores, no se atasca, no se pierde color, bastante bien, recomiendo al 100 la marca
