Let customers speak for us
from 144 reviewsWorked out great.
I’ve bought several rolls of filament of this color over the last few years, the filament is excellent. Color seems consistent between the rolls and prints very nicely. Have had zero issues.
Great value and great filament. Used it to print 300 toys for toys for tots. Went smoothly no issues at all with any of the rolls.
Great filament prints well in my Prusa MK3S+ like it a lot..
PLA arrived quickly and was used for some little pumpkin place-settings which will be used for Thanksgiving dinner.
Love it. No issues whatsoever. Excellent color.
color was on point for my nephews project that I 3D printed for him!
Very happy with the COEX PLA. Prints very well on Bambu P1S
I am a hobbyist with 3 printers and at least one runs 3 or 4 days a week. I have been a customer of COEX for about 5 or 6 years. I have always preferred buying American made products, but find it more difficult in this day and time. During the time I have been a customer, with only one exception, I have been totally satisfied with the product, as well as the delivery. The one exception involved a wrong product delivered. One phone call and the problem was immediately acknowledged. The correct product was shipped and return shipping paid for. A few days later I received an email from the OWNER of COEX. He further explained that the error was his and that his employee responsible for shipping was on vacation and he was filling in. All of this is to simply say "You can't beat American Made Products and American Service." By the way, I am 80 yrs. old and been 3D printing for 9 years. Old dogs can learn new tricks.
The clock photo is done in your Green Bay Green and Green Bay Yellow.
I was using Prusament White PETG for some prints that needed to be visually perfect. With Prusament I woudl get these black, burned blobs of filament falling off occiasionally, ruining my prints.
I switched to COEX, printed with the same profile, and it was great. less stringing and no more burned blobs.

Coex filament is always top notch. Prints come out fantastic. Never any jams or goofy things with the filament, even though it’s a transition!
