PEEK OPTIMA™ LT1 (Filament 1.75mm NAT)

PEEK-OPTIMA™ LT1 FIL 1.75mm NAT

High performance thermoplastic material, PolyEtherEtherKetone (PEEK), semi crystalline, filament for Additive Manufacture by filament fusion and other melt extrusion 3D printing processes. Colour natural/beige.

Typical Application Areas
Filament Fusion Additive Manufacture of printed parts. Suitable for use in the 3D printing of long-term implantable medical devices. Excellent sterilisation resistance. Product supplied vacuum packed and dry when produced. As PEEK is hygroscopic, drying before use is recommended. This product is based on PEEK-OPTIMA™ LT1.
