SUNLUHigh Speed PLA Filament 1.75mm, 30mm/s - 600mm/s Print Range, High Flow Speedy 3D Printer PLA Filament, Designed for Fast Printing, Good for Fast Printing, 1KG White

I've been really impressed with SUNLU High-Speed PLA! It prints beautifully even at higher speeds, with smooth extrusion and minimal stringing. The filament flows consistently, adheres well to the bed, and produces strong, detailed prints. No clogs or brittleness—just reliable performance from start to finish.If you're looking for a filament that can keep up with faster print settings without sacrificing quality, this is a great choice. I'll definitely be ordering more!

This is high quality filament! It adheres nicely to the print bed with a little heat, without me ever having to pick up a glue stick. Prints end up coming out very nicely, and quite accurate even at high speeds. Since I have a flexible build plate, I haven't had any issues removing prints once they're finished. Printing as low as 200 degrees Celsius is not an issue at high speeds (200mm/s or higher) from what I've seen on my Creality K1 SE, and I haven't had any extruder clogs so far, after using almost half the roll. The color is a nice even cool white, coming out slightly glossy.

This filament prints great and the color is perfect. The Spool opening is a bit loose for my ams lite, but an adapter helped with that. I will definitely be buying more of this one!

I tried the Sunlu filament as an alternative to the more expensive types my printer manufacturers wanted me to use. I was a tad "gunshy" of using it at first as it was "cheaper". Loaded it in my printer and was very surprised with the ease of use. Spools seem to be wound correctly as Ive never had an issue with it being tangled, yet! Time will tell if I get one of those spools. Color selection is fairly good, and has become my go to filament. At 40.99 for four spools its a GREAT deal.

Sunlu filament is a reliable choice for 3D printing, offering consistent quality that makes it easy to work with. Its performance is impressive, with smooth extrusion and minimal issues like clogging or tangling. The filament’s even thickness ensures precise prints, resulting in excellent layer adhesion and detail. Whether you’re printing detailed models or functional parts, Sunlu filament consistently delivers great results, making it a solid option for both beginners and experienced users.

I have been using this product, elegoo rapid and overture turbo for a while now. This has been a solid filament with zero issues until this last delivery. One of the spools was not completely vacuum sealed and the filament was loose and unwound to the point that this spool is unable. Not sure what happened but since it has a had a good track record I still have faith in it, just not sure what happened.

When it is good, it does the job. Load the 3kg spool and fire off functional prints. I've been working on storage project and being able to run through multiple 700g prints without having the filament run out is a blessing. I've gone through 20kg of black SUNLU HS PLA filament in the last 3 months. And the price per KG is neigh onto impossible to beat at the retail level for a HS PLA per KG.But, the niggle here is consistency.I had a 3KG spool have a section of filament that was oversized and jammed the feed tube into the printer twice on the same spool. So, two failed prints and a wasted weekend since neither of the prints were small prints. The failures were such that the filament jammed in the feed tube and then stripped out at the extruder gears right before the hot end. So, no filament out error but also no spaghetti. Just the printer making air prints until the run ends / I manually catch it.So that roll gets returned as defective and gets replaced.If you are hunting for cheap / and decent quality and this isn't a time sensitive print, a great choice.If you make your money 3d printing and failed prints eat into time and add to overhead... You might not save as much money as your would think by choosing the cheapest over a higher cost filament with better quality control.

I must say, out of all the filament I have used for mass production of parts, this has got to be the best for the money. It prints outstanding on all of my Bambu printers. For those of you with Bambu hardware, you can use the Bambu PLA profile and it will work fine. I would suggest a smooth build plate because this stuff has really good adhesion but you should not have a problem with a textured PEI.
