Polymaker PLA Filament 1.75mm Steel Grey PLA Filament, 1kg High Rigidity Steel Grey Filament - PolyLite PLA Steel Grey 3D Printer Filament 1.75mm, Print with Most 3D Printers Using 3D Filament

See bottom for most recent update - 1st review - First point- excellent material. I used my micrometer and got exactly 1.75mm. Print quality was amazing. And for the 1st 20 percent of the roll I had no issues. But the spool material (recycled cardboard) caused me some pain. I noticed it was pulling hard to spin the rolll and would even make a squeak when the roll moved a few degrees on my spool holder. 1/2 way through a 48 hour print the filament got stuck on the edge of the spool and caused my extruded to stop being fed. Woke up to the attached picture. I live in Arizona so we are the furthest thing from a humid climate. Not sure if I’m the only one with this issue but if you have a complex long print, I wish you luck. Again, great material. Just spoiled too tight. - 2nd review Update - looks like it is user error here and no fault of the manufacturer. i must have looped the pla through one of its own strands on initial instillation. seems to be printing fine now without squeaking and im expecting a good print. changed to 5 stars.

Pronts great in my K2 Plus!! Will definitely use Polymaker PLA again!

Excelente filamento, solo que es necesario secarlo mínimo unas 5 horas antes de usarlo cuando está nuevo.

Very good filament! Printing on a Prusa Core One with zero issues. Keep it dry!

Absolutely fantastic filament. All Polylite PLA is superb, but this particular color is extremely attractive for items that require dark grey filament. This will be one of the bulk purchases Iwill make in my next wholesale order from Polymaker. Highly recommended! This filament is consistent between batches. the following photos has filament from 4 different spools.
