Transition "Mystery" Color PETG

What is "Mystery" color?

Coex 3D Transition "Mystery" Color filament is the same high-quality PETG that our customers trust but in "mystery colors". 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.

PETG (PolyEthylene Terephthalate plus Glycol) is a co-polyester used in 3D printing for its durability, impact resistance, and temperature resistance. PETG is the second most popular 3D printing filament behind the ubiquitous PLA. It has qualities comparable to ABS but can be printed without an enclosure or fume handling requirements. Unlike ABS, however, PETG cannot be vapor smoothed using acetone.

All of Coex's filament is made in our production facility located in Wisconsin, USA. Coex 3D uses industrial-grade extruders and laser measuring quality control to ensure quality, consistency, and a 1.75±0.03mm diameter specification with every spool. We provide filament that gives excellent-looking and strong prints.
