What is "Mystery" color?

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.

Recommended Print Settings

  • Hotend Temperature: 215 °C - 235 °C
    • 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.
  • Bed Temperature: 0 °C - 60 °C
  • Recommended Build Surfaces/Adhesives: Glass, PEI Build Surface, Magigoo, Painter's Tape, Glue Stick

    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.

    Great quality and perfect color for functional parts prints

    In with the Mystery

    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!


    Not quite what I expected color wise, but printed well.


    Great looking product and exactly as described

    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.
