I bought a four spool refill pack. So far the first spool was great. The second spool has clogged twice on a 6hr and 8hr print. I’m hoping the other spools are not like the second spool.Edit: I’m not sure if the clog caused this or this is why it clogged but one of the planetary gears in my extruder broke a tooth. I have replaced the gear and will see if it happens again. So far all of the other Sunlu filament spools I’ve bought have been great.

Great value we use a lot of white and I have lots of reusable spools. The quality is great so is the color.

Love this filament! The white Elegoo PLA+ used to be my go to (which is also good), but I much prefer the color and finish of this matte white. Packaging was neat and I haven't noticed any tangles yet. It prints pretty good with the default settings on my A1, but after calibrating it, it's even better!

If I could give zero stars, I would. This is by far the worst filament I’ve ever used. Every print with this filament has either failed to adhere to the bed, failed to adhere to itself, or is overall terrible print quality when a print actually does work. We have attempted to dry the filament, change print speeds, adjust nozzle and bed temps, nothing fixes it. It also regularly has random layer shifts even after printer calibration? No other filament I have used has had these problems.

One of the filament spool was wounded badly and it's causing 'sticking' error on my 3D printer. Need better QC inspection.

Love the refills. This is my primary filament, and I have printed many spools of it. Nice finish, re-using the spools is satisfying. I hope Sunlu expands their "refill" offerings.Haven't had a tangle yet (that wasn't clearly my fault.)

Update: This isn't a one off issue as it happened the same way on a couple other rolls. Keep in mind this isn't happening all the time. Unless the frequency increases significantly I can live with it because of the great prices. I wouldn't recommend this filament if I was running a business as any downtime dealing with this issue at scale would probably cost you more money in wasted productivity.--------This is my 3rd spool of Sunlu PLA matte filament used with my Bambul Lab P2S. Up until now I've had zero issues, and this is after going through 2 full 1kg spools of the same filament. As I'm approaching the halfway point with my 3rd spool, I've been running into filament loading errors with my AMS 2 Pro. After a closer look, I'm seeing multiple sections where the filament looks crimped as shown in the screenshots. Each time the filament is loaded I would get an AMS error that it was slipping during the loading process. The only way I could get around the issue was to find the crimped section and cut it off, then reload it. So far this has happened a few times, luckily none of these issues occurred mid-print, only at the start. The fix is easy enough but it's a bit annoying to deal with, not to mention the wasted filament. Hopefully this is just a fluke with a partially bad spool of filament.

What can I say, cheap filament that just does the job well. No tangles so far and print quality has been great.

Buen color mate, costo bajo, aunque a veces el filamento con bobina cuesta igual y casi nunca hay existencia de este formato...
