SUNLU High Speed PLA Filament 1.75mm, 3D Printer Filament 1.75mm ±0.02mm for Fast Printing, Fit Most FDM 3D Printer, 1KG Cardboard Spool. (Black)

Very good price and I have had no issues printing

Feeds great. No issues when printing. Adheres to plate for initial layer. Not too much stringing even tho I kind of expect it until I get the printer dialed in.

I believe these are second chance rolls that have been returned, unwound, and then recoiled on a new cardboard spool. Good value for the price. I picked up two of these and put it into my filament dryer for 12 hours at 50° c and it worked fine in my Bambu P1S.

I have bought a lot of products from Sunlu because I was very happy with the quality and value.I even have 2 dryers from Sunlu.I have been printing for 10 years. I have 173 spools of filament in stock today.I was happy with Sunlu, that is until I made this purchase.I bought 4 rolls of black PLA+. Absolutely the worst filament that I have ever used. The spools were crooked (didn't work in the AMS, filament was tangle so bad that when I respooled them each roll stop the respooler because it was so tangled. They are off my qualified vendor list.

I am very happy with this. I actually didn't know (qty 4) of 2.2lbs or 1kg spools were gonna show up for that low price. I was shocked and happy. Now, how does it print. Really good. The bandwidth of hotend temp range is kinda narrow, like 5°C and anything out side of that, stringing and adhesion issues, but once dialed in on test parts, I have 4 spools to rock and roll with. I will buy more soon. I hope they offer the 4 pack value deal in most base colors, as I will do that in one large purchase. Fast shipping too.

I really like this filament. It is strong and has a nice low gloss finish to it. Pretty easy to print with it and a nice low price. The main issue with this filament is clogging of the extruder. I have 3 brand new Flashforge 5M Pro printers and this is the only filament so far that causes clogs. It seems that every 1.5 spools I get a bad clog. And most of the time it is not cleared by the standard procedure, I have to disassemble the extruder and clean filament gunk inside of the gear mechanism. On the positive side, this has made me an expert in taking the extruder assembly apart. Due to this maintenance situation, I would not recommend this filament. The manufacturer states that this filament should be used within 6 months, so I believe the clogging issue is due to the shelf life of the filament. I don't have filament laying around for more than a couple of weeks, so I would assume that keeping it longer will make the clogging issue worse. For this filament to be an awesome filament they need to make it more stable and consistent in my opinion.

I am very new to 3-D printing. So new that I just finished the filament roll that came with my new Flashforge Adventurer 5m Pro and put in a roll of Sunlu PLA black.The rolls came quickly, packaged well, tightly wound. Seems perfect to me. As for the printing, the smaller prints seemed good, on larger prints (for me that’s about an hour) a few attempts failed, a couple looked questionable and are likely re-do’s. There is some stringing, and some areas on the print that don’t seem quite right.I say the jury is still out cause I really don’t know if it is the fault of the filament or if it’s operator error. There just may be a large dose of operator error involved if I didn’t set the machine up correctly.I will continue to do some tweaking and will let you know. If you have been used to using one brand and try another, be aware that you may have to make adjustments.

Good product for a good price enough to print a bunch of stuff
