Scarlet Red PETG 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. Coex 3D Scarlet Red PETG is made with Virgin resin and high quality colorant only, with no fillers. 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. 750. 03mm diameter specification with every spool. We provide filament that gives excellent looking and strong prints.
