SUNLU3D Printer Filament, Toughness PETG Filaments for 3D Printing, Neatly Wound Filament, High Strength, Better Flow of SUNLU No Clogging PETG Filament 1.75 +/- 0.02 mm, 2KG Spool, Black+Black

This Review is for the White+Black combo pack.TL;DR: This filament is good, but the white is milky translucent. Getting the right temperatures for your printer with PETG is a must. I'll buy it again.Printer: Prusa i3 Mk3s.Nozzle: .4Nozzle Temp: 235Bed Temp: 90Extrusion Multiplier 1.05Print Speed: 50mm/sFan speed: 100% after layer 3Bed type: Textured Spring SteelI read all the reviews and spent a considerable amount of time getting the profile just right so that I could print successfully. The results of the prints have all been good with minimal stringing and only minor shrinkage/warping on large parts. Sliced 153mm disk at 3mm thickness with a 5mm hole. After the part cooled, I was left with 151x2.85mm disk and a 4.8mm central hole. This amount of shrink can be controlled for, and honestly the fault may not be with the filament, but with my slicing. Fortunately this part really only needs to be good enough.I will happily recommend this filament with only a few caveats. The first of which is, not the white color. It is less white than it is just colorless. It is a milky translucent, and the fill lines are easily discerned in the disk, even with the 3 bottom and 4 top solid fill layers. If you are looking for white, this isn't your filament. Fortunately, what I will be using this particular spool for are parts whose color doesn't matter at all. If color doesn't matter buy the white, it prints very well.Second, print with a brim. I printed some taller parts that did curl at the edges on the bed. The curl was really only noticeable when I tried to join the two edges together, but a bit of sanding on a flat sheet of glass quickly solved that problem. With the textured sheet, that is a requirement for a flat join.Third, if you are using a textured sheet, it has to be clean. Not just eat off of it clean, surgeons scalpel clean. anywhere that I accidentally touched the bed, I lost adhesion. In the first layer you could literally make out the swipe of my finger on the bed where I removed a string of nozzle drool that dropped to the bed during the preheating stage in the first layer. Give the bed another wipedown with IPA before you preheat, and don't be clumsy clearing the drool like me. After the bed cooled, the part popped itself off, the skirt did not.Do the temp tower on your computer. At 230 and below, terrible bridging and minor stringing. At 240 terrible bridging and stringing. Walking in the settings really paid off for me.

I compared Sunlu, Overture, Inland and GIANTARM PETG Filaments for a large batter box project. Of the four filaments Sunlu was the best over all.Sunlu Summary -Pros:-Warping is controllable with tabs.-Almost no strings-Good Adhesion at lower bed temps-Great Print Quality (including overhangs)-Low CostCons:-Bed adhesion at high bed temperatures (say 90) causes damage to glass bed when removing prints. very solvable use 75c.-Limited color availability.When I started out with Inland and Overture, but had trouble with bed adhesion and stringing. I was finally able to get decent adhesion with Suave hairspray at 95c while printing at 245c. The prints were very stringy and warping was a problem; I never found a hot end/bed temperature that worked well. I tried Sunlu and found that the bed temperatures that a 95c bed was too hot for Sunlu. I damaged my glass bed while removing the first print. I backed down to 75c which provided good adhesion for printing and easy removal when cold. I was able to print at slightly lower temperatures than the others (235c).Later I needed more red and Sunlu was not available, so I tried GIANTARM at the same settings with OK results except for warping. Overture and Inland prints also warped no matter the combinations of bed temp, hot end setting or tabs that I tried. GIANTARM is my second choice behind Sunlu.Other information: Parts were 190mm long (x-axis), 10mm thin (y-axis) and 338mm tall (z-axis), which probably exacerbated the warping. Printed with (mostly stock) Creality CR10S Pro V2 printers with 0.6mm nozzle and 0.4 layer (0.2 first layer for better adhesion) .

Sunlu makes really great petg and is my current go-to petg. I print on a Bambu X1C with AMS and have tried many brands of petg. Sunlu is consistently good at a great price. The print quality is fantastic and it requires almost no tweaking at all. It just works over and over again, spool after spool, producing clean quality prints.

Once calibrated, and dried, this is great and consistent filament to print with. Very, very nice for a PETG filament and easy to print with.

Czerwony to tak naprawdę taka landrynka, bardzo blady. Kompletnie inny, niż na zdjęciu.

I ordered RED!!! When printed it is just pink. It's nice and red on the site, but not at home!

Strong than PLA i love it!
