SUNLU PLA Plus 3D Printer Filament, Upgraded PLA+ 3D Filament 1.75mm, Neatly Wound PLAPro, Strong and Toughness, Dimensional Accuracy +/- 0.02 mm, 1KG Spool (Black)

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!

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.

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.

The SUNLU PLA Plus 3D Printer Filament is a solid choice for FDM 3D printing, offering excellent value and reliable performance. The filament prints beautifully, producing strong, smooth, and consistent results with minimal warping. It's especially great for beginners and experienced users alike, as it’s easy to work with and doesn’t require a lot of tweaking to get good prints. One standout feature is the filament’s strength—it feels sturdier than standard PLA, making it ideal for projects requiring a bit more durability. The consistent diameter (1.75mm) ensures smooth feeding, and it works well with a variety of 3D printers. However, the reason I’m giving it 4 stars instead of 5 is that it can be slightly sensitive to humidity. If not stored properly, it tends to absorb moisture, which can lead to stringing or rougher finishes. A filament dryer or good storage practices solve this issue, but it’s something to be aware of. Overall, this is a fantastic filament for everyday use and even more demanding projects. It’s affordable, versatile, and delivers excellent results when handled with care. Highly recommended for anyone looking for quality PLA+!

Filamenty drukują się dobrze, nie łamią, kolory żywe.

Das SUNLU PLA+ Filament überzeugt durch seine gute Qualität und Maßhaltigkeit. Mit 1,75 mm Durchmesser und einer Toleranz von ±0,02 mm läuft es gleichmäßig durch den Extruder und sorgt für saubere Drucke ohne Verstopfungen. Die Druckergebnisse sind stabil und belastbar – deutlich robuster als normales PLA. Die Oberflächen wirken glatt, die Schichten haften zuverlässig und auch bei größeren Projekten bleibt die Qualität konstant. Besonders positiv ist die saubere Wicklung der Spule, wodurch es keine Knoten oder Verhedderungen gibt. Die Verarbeitung ist insgesamt sehr zuverlässig, und das Material lässt sich leicht handhaben. Auch Anfänger kommen gut damit zurecht, während erfahrene Nutzer die höhere Belastbarkeit schätzen. Ein kleiner Hinweis: Wie bei allen PLA-Filamenten sollte man es trocken lagern, da Feuchtigkeit die Druckqualität beeinträchtigen kann. Fazit: Ein starkes, präzises PLA+ Filament mit sauberem Druckbild und hoher Belastbarkeit – ideal für Alltag und anspruchsvollere Projekte. ⭐⭐⭐⭐⭐ (5 von 5 Sternen)

Compatible con mi Bambu Lab A1 AMS Impresión a 4 colores, me gusta la calidad del filamento y acabado de impresión

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.
