SUNLU filaments are always great quality from my experience. I've used these on some printed spool holders I made a while back, and they fit great. Print quality has always seemed to be good on my Bambulab A1, and i haven't noticed any issues with adhesion, stringing, etc. that wasn't on my part. Definitely a good deal for the bundle of four.

Easy to reload the spools I saved using this filament. The product is very consistent and prints beautifully. Sunlu products have always done well for me and I print with 6 different printers simultaneously and have never experienced and issue with their products.

The SUNLU reusable spools that c9me on their other rolls of fillament will not fit these directly. They are not wide enough and the inner spool is much smaller (see pictures). However, you can take 2 spools apart and 3d print a new inner barrel and then It fits perfect. Quality seems good and the price is right!

Hands down the best filament on the market. I have tried almost every brand, but always come back because the print quality is unmatched.

First off, this filament prints very nicely. I haven’t had any problems with adhesion or in the quality of print. I did have one of four spools arrive in a bag that either wasn’t vacuumed well or had a small hole. It did print just fine without having to dry so no big deal. The only real problem was on my second spool. This was the only time I have ever had problems with a spool getting tangled. I frequently use refill spools from Bambu with no issues. Hopefully the other two spools are fine, I’ll update if there are any further issues. Either way, it’s a great price for good filament but their quality control could use some improvement.

I've used Sunlu for a long time but was very disappointed with the quality recently. The filament produced very uneven layers and had some in pretty severe production defects that caused some failed prints. Narrow sections caused the filament to stop feeding correctly. That being said, the actual white color was nice and opaque and not semi-translucent like many filaments.

Love this idea, wished they had more colors and in PETG. Specifically PETG burnt titanium. Would definitely buy a 4 pack of these. ;)

Not a lot of companies make matte black for PETG, Sunlu being one of the few. The quality and finish of this filament is amazing. Layers are smooth and adhesion is great, maybe too great since it sticks to the build plate too well sometimes. Easy to use on my P2S and very strong.
