COEX 3D

COEX 3D makes 3D printer filament at our facility in Green Bay, Wisconsin, USA. We have been in business since 1996 and are employee-owned. Our range covers PLA, PETG, PCTG, ABS, ASA, nylon and COEXFlex flexible filaments, plus COEXNext recycled filament. Advanced extrusion equipment and laser micrometers keep every spool consistent, and we make our filament to a ±0.03 mm diameter tolerance. We use prime virgin resins, colorants and processing additives, and we publish a technical data sheet for each material.

As a 3D printer filament manufacturer, COEX 3D knows that 3D printing innovation is constant. That’s why we invest in polymer science research to advance 3D printer materials. Our team takes on custom projects and works directly with customers on troubleshooting and new product development.
