Color: 1kg Pla Plus Olive Green
Size: 1 kg
Sunlu filament is one of my favorites to use on my Bambu X1C. The print quality with the built-in Sunlu profile is top-notch. Bed adhesion on both PEI, Cold Plate, and BiQu Cryo plates is flawless. I did not experience any clogging, stringing, or other issues. I always dry the filament before use, given the high humidity in my location, to avoid issues, but it is probably not necessary, as Sunlu filament is well packed with a desiccant. On some other brands, vacuum packing is lost during shipment. Sunlu has been consistently great, with every pack vacuum sealed and holding a vacuum on delivery. It loaded and ran easily in my AMS 2 Pro unit.

Color: 2kg Pla Plus Grey+grey
Size: 2 kg
ve had consistently excellent results using SUNLU filament, and it has become one of my go-to brands for everyday and professional prints. Right out of the box, the filament is well-spooled, clean, and free of tangles, which immediately inspires confidence before a print even starts. In terms of print quality, SUNLU filament delivers smooth, reliable extrusion with very consistent diameter throughout the spool. This consistency translates directly into clean layer lines, strong layer adhesion, and a noticeably smooth surface finish on completed prints. I’ve experienced minimal stringing and very few failed prints, even on longer or more detailed jobs. Another standout aspect is how forgiving the filament is across a range of temperatures. It prints predictably and adheres well to the build plate without excessive warping, making it suitable for both beginners and experienced users. Color quality is also impressive—vibrant, even, and true to what’s advertised, with a professional-looking finish every time. Overall, SUNLU filament offers an excellent balance of quality, reliability, and value. Whether printing functional parts, decorative items, or prototypes, it consistently produces dependable results. I highly recommend it to anyone looking for filament they can trust print after print.

Perfect pack to have for anyone with a 3d printer. Sunlu pla will always be my go to filament and this pack worked great when i would randomly need a little bit of a specific color. each spool is 1/4 the size of a traditional spool. they are wound nicely to prevent tangles. All my prints come out crystal clear and smooth. Absolutely a steal for the price.

Color: 16 Color Bundle
Size: 4 kg
This 16-color PLA Plus filament bundle has been really fun to use for my 3D printing projects. The colors are bright and pretty true to the pictures, and having so many options makes it easy to mix and match without running out mid-project 🎉💡. It prints smoothly and sticks well to the bed, which matters when you want crisp details and clean finishes. Some spools are smaller than standard, so they run out a bit faster if you’re printing large items, but for colorful minis, gifts, and creative ideas this set is awesome. If you’re a hobbyist or just love having a rainbow of options at your fingertips, this is a great value and really makes printing feel more exciting 🎨✨.

Good Quality. Nice large roll for making large prints using my Ender 5 Max. Had to make up some rollers to hold the reel since it was so heavy, but filament works great with no issues in the prints.

Color: 4kg Pla Plus White+white+white+white
Size: 4 kg
Neatly and tightly spun, no tangles. Works for what I need it for, which is 250g+ prints. One downside regarding flexibility that I noticed is that when it is exposed to air, it becomes slightly more brittle than the PLA that I am used to working with, and it would snap a little bit easier while attempting to feed it into my printer's nozzle. Other than that, works great. Prints fast, the finish is flat and smooth.
