SUNLU PLA 3D Printer Filament, Black, 1KG

This black PLA has performed so well that it has quickly become my new go-to filament for black prints. The quality has been excellent, with consistent extrusion and very reliable printability from the first print onward. I’ve also had great bed adhesion, with prints staying firmly in place without issues. The black color is deep and consistent, and the finished prints have a clean, professional appearance with good detail. All four spools have fed smoothly, and I haven’t experienced any tangling or knots, which is a big plus when running longer prints. The 4-pack is also a great value for the money, especially considering how consistently this filament has performed. After using all four spools, I’m comfortable saying this has become the black PLA I reach for first. I’ll definitely be buying more when I run out.

This filament runs flawlessly on the Bambu Lab A1 straight out of the package. Bed adhesion is spot-on, extrusion is remarkably consistent, and layer lines are virtually invisible even at high print speeds. I’ve had zero issues with tangles, clogs, or stringing. Dimensional accuracy is right where it needs to be, which makes tight tolerances and functional parts fit together without hassle. The color is rich and uniform across long prints, and the surface finish comes out crisp every single time. It has quickly become my go-to choice for both detailed decorative prints and durable mechanical pieces. Highly recommended for anyone looking for reliable, high-speed performance.

I love this brand of filament for my Bambu Lab A1 printer. I have had no issues with it at all. No feeding issues, no clogging issues. It prints perfect every time. Highly recommend Sunlu PLA 3D Printer filament.

I was looking for a less expensive option for filament to use with my BL P2S. This is my first printer, so I was kind of nervous about venturing away from BL filament. After doing a lot of research and reading on FB groups, I made up my mind to try Sunlu out. I'm glad I did! It is a great filament and prints just like BL's filaments, for a lot less $ (especially when you catch it on sales). The colors are great with a wide verity to select from. I've never had an issue with it coming loose or bending off of the bed while printing. I haven't really printed anything that requires much heat resistance, so I really can't give my opinion on that. But if you are looking for a great filament at a cheaper price, don't hesitate to order some Sunlu.

Bang for the buck it works great. I use it for my test models and it does just what I need. Maybe with some experimentation I could eliminate the only noticeable issue, that would be warping at the edges as it cools and lifts off the plate. Not horrible, but it does happen. Don't know if it's enclosure, plate or head temp that is needs tweaking, but I've never have any such issue on my CORE ONE+ using Joseph's genuine filaments. Bottom line, if I'm going to burn a bunch PLA mocking up a prototype this does the job. I give it a solid 4 out of 5 stars. Now that I'm looking at the picture I'm posting I also see some signs of stringing, very minimal though. Then some layer imperfections all at locations where internal features begin and end. They all have to do with my printers settings, I'm sure they could be worked out if I had the time or a Filament Profile. I just checked and PrusaSlicer, they have 3 Sunlu profiles(PETG, PLA & PLA+ 2.0). I'll take a look at the profile and see what settings have been modified. Hunch is that it will fix all my problems with this product. If it does, I'll come back and give it 5 stars. Happy Printing!

One of My go to filament. Love this brand. Never have problems and the prints come out looking great. Also they have a great variety of colors and filament types.

A lot of black filament prints closer to dark grey. This one is actually dark - a true black that stays black on the finished part, which matters when you're not painting afterward. It printed well for me and the price is hard to argue with. Easy repeat buy.

I'm using a Prusa I3. It's been a good printer so far, but I've been feeding it filament from Prusa. Recently I switched to this SUNLU black PLA, and I've seen issues. One is definitely the manufacturer's fault. The spool it comes on is a typical plastic bobbin. They put a small hole in the bobbin to thread the filament into, to hold the end in place while they wind it. Unfortunately the hole is on the inside of the cylinder instead of on the side, which means there's a tiny nub of filament sticking through the bobbin's inner ring - the thing it rotates on as filament gets drawn by the printer. Once a revolution, this tends to get caught on the printer's support rod, and the filament stepper motor then has to pull against the weight of the whole spool to get the next inch of PLA. I can't be sure because I wasn't watching it, but I think that's why a 10 hour print job failed partway through - the tension caused something to get misaligned and the printed model got knocked over. I tried cutting off the nub, but it's about impossible to get it all, so my workaround involves electrical tape over the nub, an extra tube between the support and the bobbin, and lithium grease. So far I think it's working, but witchcraft involving lithium grease shouldn't be necessary The other issue is that this stuff seems fussy about temperature. Printed at 215, it was messy and stringy. At 210 it's still prone to leaving threads all over the print job, but it's better. I never had this threads problem with Prusa's filament. Maybe it's a matter of tuning and experimenting but I can't say i'm satisfied. I'll note I also got some PETG translucent from SUNLU and it didn't have this stringing problem, but then PETG isn't PLA. Bottom line, I think I'll stick to Prusa's more expensive PLA in future, and do more with PETG, as it doesn't seem harder to print and seems to come out a bit better. I think I can finish my current project with this PLA, but I don't quite trust it. For people concerned about color, though, this is a nice rich deep black, with some gloss (where it doesn't string). Addendum: I had ongoing adhesion problems with this stuff. A model that printed fine with Prusa's house PLA filament would routinely come off the platter during printing with this stuff, and in the end I had to add extra material to the model's base, and print with a brim, to get it to work. I got a usable print in the end but it took half the spool to figure out how, after trying realigning the printer, cleaning the platter with acetone and alcohol before each attempt, etc. The loss of time is what decided it for me - there's not much more annoying than having a 6 hour print job fail after 3 hours, except for when it happens 3 times in a row.

I recommended with my all heart I would like to thank The seller for that product Great shape great color , work perfectly and 200C No bubble , It is a perfect choice

خمس مرات ينكسر علي الفلمنت وقت الطباعة وينحشر في المجرى الشركة كويسة بس واضح ان التخزين سئ جداجدا

It breaks every time between print to print and sometimes mid print I'm not buying this fillement again

Al principio costó encontrar las temperaturas idóneas para una buena impresión, pero una vez resuelto, la calidad de las impresiones son muy buenas.

جودة الطباعة جيدة لايوجد فيها مشاكل ولكن لا يكاد يمر علي قطعة أطبعها إلا وينقطع الفلمنت في منتصفها أي حركة صغيرة ينقطع وأكون قد تركت المنزل وتركت الطابعة تكمل عملها لأعود وأرى أن الطابعة متوقفة بسبب انقطاع الفلمنت ولا أوصي باللون الأسود إلا للحاجة له لأنه يخفي جمال التفاصيل بالنسبة للبائع فهو بائع جيد والبضاعة وصلت بأقل من أسبوع
