Coex 3D Transition "Mystery" Color filament is the same high-quality PLA that our customers trust but in "mystery colors". We sell 1kg of Mystery filament for the same price as our 500g spools, so it's a great way to give our filament a test drive!
These varying colors are the result of our changeovers from one of our standard colors to another during the production of our filament and cannot be reproduced. While supplies last. Items are not returnable or refundable due to color. "Mystery" color filament is limited to availability as we make changeovers. If you cannot add it to your cart, we are sorry, but we are out of stock.
Note: These are not a rainbow filament. The color change in each spool will vary and be very gradual.
Coex 3D Mystery PLA - The most environment-friendly 3D filament solution. Because of its low toxicity and ease of printing, PLA (Polylactic Acid) filament is a very popular choice in the 3D printing community. It looks great, is extremely easy to print with, and has generally good mechanical properties. It's perfect for prototypes and decorative models. We provide filament that gives excellent-looking and strong prints.
Coex's PLA is made with Virgin NatureWorks Ingeo 4043D resin, high-quality colorant only, and no fillers.
All of Coex 3D's filament is made in our production facility located in Wisconsin, USA.
As good or better than most competitors + or prime.
Important! This temperature range may seem hotter than you're used to for other PLA filaments. Using 100% virgin resin causes our PLA to require slightly higher printing temperatures.
Tolerance: At Coex 3D, we use multi axis laser measuring heads to ensure a tolerance of ±.03mm.
Quality: All Coex 3D printer filament is manufactured in our Green Bay, WI production facility. This allows us to ensure consistent quality for every spool through control of every aspect of the manufacturing process.
Packaging: Every spool of Coex 3D filament is thoroughly dried in our industrial dryer before being sealed. Spools are sealed with desiccant in a 4mil thick vacuum bag.
Tested: Coex 3D doesn't just sell filament, we use it on a daily basis. Our 50+ 3D printers are constantly running with our filament. We rely on our quality as much as our customers do.
Awesome Filament at a Bargain Price - Interesting Colors - Great for Prototypes or One-offs
I've been using COEX filament for many years and have visited their plant twice. Very friendly and welcoming. The quality has always been consistent and reliable. The Mystery PLA spools are a great bargain. Sometimes interesting colors, sometimes bland but useful for prototypes. Grab these especially when they are on sale - you will not be disappointed.

I only use Coex.
I've tried other filaments in the past and Coex is the only one I found that's 100% consistent and never fails.

Sadly disappointed.
I bought 3 spools of the "Mystery" colors. One regular PLA, one PLA Prime, and one PLA Silk. The description makes it sound like the spool transitions colors throughout. So far, this has not been the case. ALL THREE SPOOLS appear to be just white all the way through. I am about halfway through the regular PLA and still just white. I would have even been happier if I got 3 different color spools but no, all. White.
Quality wise, it seems decent enough after getting the temp/speed down, (did have to slow down a bit and raise the temp about 8 degrees).
Probably will try another company next time, unless the PLA Prime is absolutely phenomenal.
