Polymaker PolyT PLA Bioplastic Based 3D Printing Filament, Matte PLA Filament, 2.85mm Filament Cotton White 1000g(2.2lb), Fit Most FDM Printer

It prints very well on our Ultimaker S5.Layer and bed adhesion is great and parts come out very sturdy.The matt finish makes it look really good.If you're in need of a 2.85mm filament, but it, it's great.

The filament is too soft before printing (easy to get grinded) and after - parts are very fragile and layers disconnect (print temp 210 degC). Horribly strong adhesion to glass bed - difficult to remove flat prints. Will not buy again.

I was worried that it might clog or jam my Ultimaker but I’m pleased to say it was great! I’ll be buying more.

Of the half dozen PLA filaments I have used, this PolyTerra filament is my favorite. I have the Ender 3 V2 and as long as the filament is kept dry, like most, is prints great. I got a 2 roll package of the Black PolyTerra and one of the bags had lost its vacuum. I tried printing with that one first and gave up after 3 attempts. It was not adhering to the plate, stringing like crazy and just made a mess. I opened the other roll and it printed perfect. After baking the first roll at 120F for about 5 hours then sitting on the shelf a few days, it printed just as well as the roll which did not lose its vacuum so good as new.In addition to a great filament, the rolls come in resealable bags which none of the others I have tried do. The rolls are also on recycled cardboard, another plus. Not to mention a planted tree with each roll (gimmicky but hey, still nice). Final plus: the single roll orders contain larger desiccant pouches than most. Unfortunately, the double roll packages did not. They just had the tiny ones.

I was shocked at how pliable this filament is right out of the package. It was bendable to nearly 90 degrees without any snapping which....I guess is not bad? At least it's not brittle. But it also means it's incredibly finicky. I tried the default PLA setting on cura and got all sorts of popping and crackling, inconsistent layers and even some burnt areas.I have a lulzbot mini and it has been extremely reliable and prints regular PLA like a dream. I've tried about 15 prints with this filament and no matter what setting I tweak, every print has some glaring issue whether it be weak layer adhesion on only a couple layers that causes the print to snap in half, insane spider webbing regardless of temp, or bed adhesion issues on small parts.The filament seems to be soft enough to come out of the extruder a little all on its own even at temps of 170-1755C, far below its suggested melt point of 190C and I have to sit there and babysit the auto level process to make sure some little bit of filament hasn't escaped and messed with the contact.I was excited for the carboard spools but if I have to mess with the settings this much every time I print, I really don't feel like it's worth it.People in drier climates might have more luck, but here in humid Florida, I'd say this stuff is a no-go. I will be returning the second unopened spool I bought and exchange it for the regular polylite PLA which I've had no issues with.
