2KG PLA 3D Printer Filament Bundle - 1.75Mm Dimensional Accuracy +/- 0.02Mm, Reusable MasterSpool, Black+Grey Review

The Sunlu name comes up often when recommendations for FDM material are asked for. Recently, I picked up some PETG and this PLA. The master spool thing was also something I wanted to check out. Disappointing. Sealed up as it was, the material should have been dry. Nope. Lots of pops and sizzles and artifacts in my prints. Ran it through several cycles in a Sunlu dryer, and while this did improve things, the roll was still not dry. :(

OK, I get the idea. If you use a lot of filament those spools wind up in the trash. Only so many can be used for Christmas lights and extension cords. But the spool I have is so-so. First of all, the filament and the spool - there's a 1" gap. That means that when the spool starts to get about half used you'll get tangles. Next, it had a bunch of dist and white particles. I use a filament cleaner to remove contaminants as the filament feeds, but without that these particles would definitely…

The filament roll that came on the master spool was wound correctly. However, the second spool was tangled before even opening the spool up and adding it onto the master. Originally wanted to stop the excess plastic from additional spools, but will likely not buy from this again

When I tried to mount the second roll of filament the spool kept coming apart and filament unraveled, creating a huge mess. Maybe just operator error, but I'll stick to spools that don't come apart.

The filament prints just as good as some of the more known names but with less waste since you can order refills instead of getting a new spool every single time.

the filament on the roll ran ok. the problem came with the extra filament . the refill roll wasnt sealed great and when placed on the roll it was obvious that the roll was tangled. not runnable at all. after running it thru a impromptu jig i was able to hand roll it onto another roll and use it. not a purchase ill make again
