Description
This high-performance PEI filament is manufactured from premium polyetherimide resin, offering an exceptional combination of high mechanical strength, dimensional stability, and heat resistance. It is inherently flame retardant and classified UL94-V0, making it an excellent choice for demanding applications.
Raw Material Approvals
- Aerospace FAR25.853
Our filaments are produced from high-quality raw materials with close tolerances (+/- 0.05 mm), allowing for precise and failure-free 3D printing. They are low emission, odor-free, shrinkage-free, and provide good layer adhesion. Compatible with all standard 3D printers, each spool is carefully packed in resealable zip bags for easy use.
