SUNLU 4KG 3D Printer Filament PLA Plus 1.75mm, 1kg Spool, 4 Packs, White+Red+Green+Blue

I’ve ordered and used multiple spools of filmaent from SUNLU and it has quickly become one of my go to filaments. The print quality is consistently excellent, always has smooth layers, strong adhesion, and I have noticed it has an improved strength compared to standard PLA. The filament is very consistent, I have experienced no clogs and no surprises. It feeds smoothly through the printer and prints cleanly even on longer jobs. Tthe results look great right off the build plate. Another big plus is how easy it is to work with. It prints at typical PLA temperatures, has minimal warping, and doesn’t require a heated enclosure. Bed adhesion is solid, and the finished prints have a nice surface finish with strong layer bonding. The spool is neatly wound, vacuum sealed, and arrives dry no tangles, no headaches. For the price, the quality is hard to beat. I really like this shade of pink as it isn't too bold, it's a nice subtle pink which is great for Easter decorations.

I’ve been using SUNLU PLA filament for a while now, and I’m really impressed with its consistency and performance. The filament comes well-spooled with minimal tangles, and it feeds perfectly through my printer every time. It prints smoothly, with excellent layer adhesion, and very little stringing or warping compared to other PLA brands I’ve tried. The finish on prints is clean and slightly glossy, which makes models and decorative pieces look professional. I’ve printed both detailed models and larger pieces, and it handles both equally well. Dimensional accuracy is reliable, so parts fit together as expected without post-processing adjustments. Another big plus is how easy PLA is to work with, and SUNLU’s quality makes it even better—strong enough for functional parts, but still easy to sand and paint if needed. Overall, SUNLU PLA is a top-notch filament that combines ease of use, excellent print quality, and reliable consistency. Definitely one I’ll keep stocked.

I've tried a lot of different PLA brands, and SUNLU consistently delivers the best results. The filament is well-packaged, neatly wound, and the diameter is extremely consistent — no tangles, no clogs, and no unexpected surprises. Print quality is excellent straight out of the box. It has great layer adhesion, minimal stringing, and produces smooth, clean finishes even on detailed prints. I especially appreciate how reliable it is across long print jobs — perfect for both functional and decorative parts. The color is vibrant, the material prints beautifully, and for the price, it’s hard to beat. I’ve had zero print failures with SUNLU PLA, which saves time, money, and frustration. If you’re looking for affordable, high-performance PLA you can rely on — this is it. Highly recommend for both beginners and experienced makers!

Why did you choose this product over others?: I have tried many different brands of filament and this one has not yet let me down, I have not yet had a failed print with Sunlu PLA Plus. It adheres to the bed well but not too well, it is neatly wound on the spool. The prints are accurate with little or no warping. The colour range is good and vibrant apart from the green which is a little insipid. What can I say, it ticks all the boxes. It isn't the cheapest filament but buying cheap doesn't often get you the best results. EDIT :- 28th June 2025. There has been one blemish on Sunlu's perfect record, one roll of filament was too thin and didn't feed properly. The filament is supposed to be 1.75mm but when I checked it this spool varied between 1.33 and 0.9mm. I sent it back. This was not a big problem because the fault was obvious and Amazon are good at returns if there is a problem. I am still going to use Sunlu PLA+ filament because almost all of the spools are good.

great quality, great price

It is okay but I can't use it for prints with a lot of details

I've been mostly using this colour to print out Heroquest furniture, because it has a similar chocolatey colour to the original. Doesn't seem to handle overhang as well as the other PLA+ I've used (Creality PLA+ Black) as you can see from my Benchy boat test, but I was able to get a better result with some temp adjustments. I recommend a 205⁰ nozzle to reduce overhang and a 60⁰ heated plate to prevent base-warping. I ran my first few prints on 45⁰ plate, as is standard with my generic PLA preset on my printer but minor warping occured. 60⁰ held the base firmly in place.
