Great Colors for Functional Prints
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.

Sunlu spools do not fit, but can with a printed insert
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!

Love this filament
Been doing a marathon of 3d printing for the last month and a half. I’ve primarily used SUNLU filaments because when I previously 3d printed I grew tired of all the plastic waste of the empty spools. So I initially got SUNLU filaments because of the promise of reusable spools. Even though at the time I purchased these refills they cost pretty much exactly the same price as if I would have got the spools I love having the option as I my current projects are large easily taking 3-5 spools for each project. As far as printing I’ve experienced zero problems with any of the prints. I’m extremely happy with all my SUNLU filaments purchases.Note when buying additional filaments and you are attempting to color match make sure all the description match. The PLA 2.0 / Plus / matte all might have a slightly different shade of color due to the additives that give that filament the properties characteristic of the type of filament.I will continue to use SUNLU when possible.

No adhesion issues. Always prints good quality models. I will continue to buy from this seller.

Good filament at affordable price. QC needs improvement.
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.

Sunlu fix the refill spool winding
I actually enjoy Sunlu High Speed filament. THe matte color is some of the best of the PETGs. Once dialed in, it prints very well. But these refill spools are absolutely terrible. They designed to go onto the spool very well, but the winding is awful. I’ve lost days of print time due to the spools locking up from the winding embedding deep into the spool. This does not happen on their prefilled spools. After dozens of kg of Sunlu PETG refills I can longer purchase or endorce the product. Buy the full spool or look to another brand.ProsGreat mattePrints well once dialed inConsRefill spools are wound terribly. Completely worthless and should be rewound if you’re going to use. Buy the full spools or don’t purchase until Sunlu can get this fixed.

Good filament at a great price

Neon colors… forever!
The colors are so much fun and the filament prints extremely well (at least on my Bambu labs). It’s only the refills, spool is NOT included. They come with a bunch of transparent stripes to re-attach the spool (I guess). Orange and pink are more muted, yellow and green are very bright!

No es tan bueno como dice el fabricante, hice pruebas y otros filamentos PLA sencillos son mas resistentes

Benutze so gut wie nur noch Sunlu Filament, da mir die Haftung und die Farben sehr gefallen. Allerdings muss ich das Filament bei meinen Drucker mit 220°C Extruder- und 60-63°C Betttemperatur drucken. Ansonsten passt das Filament für meine Druckobjekte sehr gut.
