As manufacturers across Northeast Wisconsin continue looking for ways to improve efficiency, reduce lead times, and accelerate product development, 3D printing has evolved from a prototyping tool into a valuable production resource. The success of any 3D printing application, however, starts with one critical factor: material quality.
At COEX 3D, we are proud to manufacture engineering-grade 3D printing materials right here in Green Bay, Wisconsin. Using high-quality virgin resins, advanced extrusion technology, and strict quality control processes, our mission is simple: provide industrial users with reliable materials they can trust for functional, repeatable results.
Unlike many imported filaments that prioritize low cost over consistency, COEX 3D focuses on performance. Every spool is manufactured with tight dimensional control, monitored with laser measurement systems, and produced from carefully selected materials designed to meet the demands of engineers, manufacturers, and product developers.
Why Local Manufacturing Matters
When your production schedule is on the line, waiting weeks for materials is not an option.
Because COEX 3D manufactures filament in Green Bay, local businesses benefit from faster access to materials, responsive technical support, and direct collaboration with a team that understands the needs of Wisconsin manufacturers. Whether you’re developing prototypes, creating assembly fixtures, printing replacement parts, or supporting low-volume production runs, having a local material partner can significantly shorten development cycles and reduce risk.
Our team regularly works with manufacturers throughout the Midwest to identify the best material solution for specific applications, helping customers move from concept to production quickly and confidently.
Protect Electronics with ESD-Safe PETG
One engineering material seeing increasing demand is ESD-safe PETG.
Electrostatic discharge (ESD) may be invisible, but it can create significant problems in environments where sensitive electronics are handled. A small static discharge can damage circuit boards, sensors, semiconductors, communication devices, and other electronic components before a product ever reaches the end user.
Many companies are already familiar with ESD-safe workstations and flooring. However, they often overlook the fixtures, trays, housings, and tooling being produced with standard plastic materials. Traditional 3D printing plastics act as electrical insulators, allowing static charges to build up and potentially discharge into sensitive components.
COEX 3D’s ESD-safe PETG was developed specifically to address this challenge. Manufactured in Green Bay using premium virgin resins, the material provides static-dissipative properties while maintaining the ease of printing, toughness, and chemical resistance that have made PETG one of the most popular engineering materials in additive manufacturing.
Typical Applications for ESD-Safe PETG
- Electronics assembly fixtures
- PCB handling trays
- Test equipment housings
- Robotic end-of-arm tooling
- Semiconductor manufacturing components
- Sensor protection enclosures
- Production line workholders
- Custom packaging for sensitive electronics
For companies involved in electronics manufacturing, automation, controls, robotics, telecommunications, or medical device production, ESD-safe materials can help reduce failures, improve product reliability, and support quality control initiatives.
