About this item

Fast Color Change: SUNLU Silk Rainbow filament changes color every 8 meters. Faster color changes and more color variations can be seen in 3d prints
Shiny Silk PLA Filament: Compared to regular PLA 3D printer filament, Silk PLA 3D filament has a glossy, smooth, silky surface
Note: The colors may change with each roll of Silk Rainbow Filament, so the initial color of each roll may differ from the image, but the overall color composition remains consistent
Filament Spool Dimensions: 1KG Spool Diameter: 195mm(7.68 inches), Spool Width: 57mm(2.24 inches), Spool Hub Hole Diameter: 63mm(2.48 inches)
Recommended Settings: For optimal results with Silk Rainbow Filament, we recommend a nozzle temperature of 205-235°C, a bed temperature of 50-60°C, and a print speed of 50-200mm/s
Neatly Wound Filament: SUNLU introduces the first PLA filament with a neatly wound design. The consistent winding ensures there will be no tangling, or clogging during the printing process
Printing Tips: Silk 3D printer filament has great color and shine, higher printing temperatures and lower speeds for a glossier finish, making it ideal for printing arts and crafts
Vacuum Packaging: SUNLU 3D printer filaments are sealed in airtight vacuum packaging to ensure they stay moisture-free
Silk Rainbow Filament 1.75mm: SUNLU 3D printer filament offers a dimensional accuracy of +/- 0.02mm, making it compatible with nearly all 1.75mm FDM 3D printers
SUNLU's Main 3D Products: SUNLU offers a variety of high-quality 3D printing products, including 3D printer filament, filament dryer, filament connector, 3D printer resin, and other accessories

    Sunlight is very reliable. I can start a print and leave it. Most reliable filament I’ve found. No tangles, great color and wonderful prints every time. Creality K1C printer loves it!

    This filament works very well on my Bambu X1C no stringing and have had very good results on all the prints I have completed with it. I will likely buy again.

    4.0 out of 5 stars Prints great, but needs to be babysat
    Reviewed in the United States on December 14, 2024
    Print quality with my Bambu A1 (no AMS) is wonderful. The shimmering silver is a gorgeous color, and I'm happy with my results. However, while printing, the spool likes to unwind itself and wrap around the spool holder. I can't be anywhere else while the print is ongoing, or else it jams. Something's not right with the way the filament is wound in the spool, and it's incredibly frustrating.

    5.0 out of 5 stars Cotton Candy Goodness
    Reviewed in the United States on December 10, 2024
    The color is silky and perfectly pink. As far as print quality, I was surprised since it was PLA+ and the last 3 rolls I've had were eSun and always had issues. Sunlu had no stringing and the prints look like cotton candy or bubble gum. I only post a review because I have only had a good experience with Sunlu filament.

    0.4mm nozzle
    65c bed
    220 nozzle (could have reduced by 5 and been okay)
    0.16 layer height
    Creality CR-6 SE

    No jams, clogs, neatly wound and I have yet to refill the spool, but a reusable spool is a great idea!
    No, I did not receive anything for the review, I just like Sunlu (I use their filament dryer to print from too).

    Overall, this is a very well priced product. It is very strong works great for a multitude of prints, including functional and aesthetic. flow is super easy through the printer and has good bed adhesion.

    1.0 out of 5 stars 4-pack of "shiny" silver is dull, bad batch?
    Reviewed in the United States on October 8, 2024
    I've already used a couple spools of Sunlu's PLA+ Silk Silver, and loved the results. I'm working on a big project that will use 8 KG of silk silver, so I was happy to find Sunlu sold a 4-pack at a discount. I was mid print, finishing up a spool from batch 02140503A, when the spool ran out, so I opened the 4-pack and grabbed a spool to finish the print.

    I noticed 3 thing in the process of loading the filament. First, the vacuum on the bag seemed weak compared to normal, and 2nd the spool was the newer Sunlu spool, different from the single spool I had bought just the week before - all 4 spools were identical. Third, during loading and purging the filament, I head the telltale pops that indicate moisture is present, so I figured the filament wasn't dry anymore. I let it print for a while anyway, and after 1-2mm I realized that the filament did not look good, the result was very hazy. Instead of a shiny silk, I had a normal gray filament.

    So I paused the print, dried the filament for 3+ hours at 131C, and then resumed the print. If anything, the filament looked even worse now.

    So it seems I've received a bad batch, ID 02840428A. This is bad enough that I can't use it at all, and since all 4 are from the same batch, I assume all 4 are bad.
