Polymaker 5kg PETG Filament 1.75mm, Strong PETG 3D Printer Filament Grey - PolyLite PETG 3D Printing Filament, Cost Effective Large Roll PETG 3D Printing Filament for Big Projects

Over the course of seven months, I could not get this filament to print correctly. I tried a gazillion profiles and dried them for 48 hours straight. Two 5kg spools and one 1kg spool—all three are garbage. I also tried a different printer. In conclusion, this stuff is garbage. DO NOT BUY!! ******************* UPDATE 1/22/2025 ********************** I got excellent prints after calibrating Flow Dynamics for this filament; it was a user error. If you are getting poor bed adhesion and under extrusion, calibrate Flow Dynamics. Please see the updated pics

Very stringy and zits when it arrived dried for 6 hours as i usually do with Petg and it's still totally unusable. Tried printing a few thing and was about to return it and figured I would try to dry again due to it seeming like it was still wet due to the way it was printing. Finally dried for 12 hours and now it prints about average but the stringing and zits are almost completely gone. Luckily i can dry this because I have a very large dehydrator that fits the 5kg roll. Petg is dried at 65°C (149°F) and my oven doesn't go that low.

I don’t know who is rolling these 5 KG spools at Polylite, but it’s not the quality I’ve come to expect. I’ve had three tangles so far with a fresh spool, which have failed prints part way through. I highly recommend printing a respooler and respooling it yourself for safety. Disappointing.

I can confirm what a previous reviewer said. It did have a ton of strings and zits.
