Let customers speak for us
from 97 reviews![White PLA](https://cdn.shopify.com/s/files/1/0603/1795/8327/files/White-PLA-coex3d-87084456_70x70.jpg?v=1719436493)
Have a big multi day print project using black and white. I have used COEX PLA since the early days of my 3D printing hobby. (It's made in the US). Printed 38 pieces using the a 5lb spool. Came out great!

My people are loving the color. Prints great.
![Translucent Blood Red PLA Prime](https://cdn.shopify.com/s/files/1/0603/1795/8327/files/Translucent-Blood-Red-PLA-Prime-coex3d-87089254_70x70.jpg?v=1719436331)
This PLA prints very nicely. Would buy again
![Transition "Mystery" Color PETG](https://cdn.shopify.com/s/files/1/0603/1795/8327/files/Transition-_Mystery_-Color-PETG-coex3d-87087577_70x70.webp?v=1719436239)
I bought this because I do a lot of stuff where color doesn't matter. This roll started out jet black and is getting lighter. Truthfully, I see it in the filament but not the final prints. I'm glad Coex offers this rather than reprocessing or wasting or whatever is done with it.
![Stone Gray PLA](https://cdn.shopify.com/s/files/1/0603/1795/8327/files/Stone-Gray-PLA-coex3d-87085644_70x70.jpg?v=1719435982)
Very happy with my recent purchase of Coex pla. It is great to know I can get a good American made product from so local to me, here in Wisconsin. Keep up the good work!
![Metallic Gunmetal Silver PLA](https://cdn.shopify.com/s/files/1/0603/1795/8327/files/Metallic-Gunmetal-Silver-PLA-COEX-3D-87108131_70x70.jpg?v=1719434196)
Nice color and prints great. Love this brand.
![Navy Blue PLA](https://cdn.shopify.com/s/files/1/0603/1795/8327/files/Navy-Blue-PLA-coex3d-176848274_70x70.jpg?v=1719435090)
Love the deep blue color unique. Just
Like the other Coex product this stuff prints great!
![Rust Orange PETG](https://cdn.shopify.com/s/files/1/0603/1795/8327/files/Rust-Orange-PETG-coex3d-87110957_70x70.jpg?v=1719435456)
I highly recommend it for anything functional that needs to survive outside and be highly visible like these Electric Fence Cutout switches we make with it.

![Transition "Mystery" Color ASA](https://cdn.shopify.com/s/files/1/0603/1795/8327/files/Transition-_Mystery_-Color-ASA-coex3d-87131689_70x70.webp?v=1719436124)
Same great quality as the regular Coex ASA Prime colors, just significantly less cost. This is my go to filament when I'm prototyping designs. It does no good to prototype with a different material or manufacturer. This saves me money and I don't have to worry about running out of my final design colors when I'm testing things. Yeah, I've had a few spools with some pretty ugly colors - not a fan of transition pink, blech ;-) - but who cares? It's not like I was looking for repeatable colors for production prints. Also had spools with very interesting and cool looking colors. Luck of the draw on colors, but the filament is great.
![Black ABS](https://cdn.shopify.com/s/files/1/0603/1795/8327/files/Black-ABS-coex3d-87102522_70x70.jpg?v=1719427471)
I have been using COEX ABS exclusively for over three years. It works well in all my machines, is American made and always available. Multiple times I have order ten rolls or more. Great communication. Highly recommended. Thanks!!

Great quality and perfect color for functional parts prints
![Gamer Green (Chartreuse) PLA](https://cdn.shopify.com/s/files/1/0603/1795/8327/files/Gamer-Green-_Chartreuse_-PLA-coex3d-87105950_70x70.jpg?v=1719433285)
I love this color. I bought it just because I thought "gamer green" just sounded funny but my goodness to I love using this stuff. From cthulhu figures to dumb little toys this stuff gets the job done.

Love the stuff! If you can make it to their shop, you can dig around and find a similar color to what you were looking for. I also love the colors that have the super subtle metal flake in it. Works perfect for my classroom projects! Keep it up COEX!

Perfect color for perfect print.
