Technical information:

Polyether Imide (PEI) Ultem 9085 is an amorphous, high performance thermoplastics with a glass transition temperature (Tg) of 186 °C. This material features superior mechanical performance, flame retardancy (UL 94-VO rated) and strength-to-weight ratio. 

The 3D4MAKERS PEI Filament has unique properties because it does not come into contact with water during the production process and is directly packaged in a vacuum packaging. These properties make the 3D4MAKERS PEI Filament particularly suitable for usage in FDM and FFF 3D printers.

To get the best results while printing we advise you to keep the 3D printer in a room where there is hardly any draft and/or temperature fluctuations. We recommend to use a closed system.

When the 3D printer is not being used it is important to keep the 3D4MAKERS PEI Filament in a bag and stored in a cool, dry and dark place until it is used again.
