PEI also known as Ultem is a high performance thermoplastic filament designed for engineering and industrial applications that demand strength, flame resistance, and thermal stability. With excellent mechanical properties and inherent flame retardance, PEI is commonly used in aerospace electrical and automotive industries where regulatory compliance and durability are critical.

FormFutura PEI filament is made for high temperature FDM 3D printers with all metal hotends and heated build chambers. It provides excellent dimensional stability with high strength to weight ratio and resistance to high temperatures and chemicals. PEI also offers naturally low smoke generation and is ideal for producing functional end use parts and advanced prototypes.

Choose PEI filament if you are looking for:

• Strong and lightweight prints with thermal and flame resistance
• Reliable mechanical properties across a wide temperature range
• Ideal material for regulated applications in aerospace and automotive
• Suitable for functional high performance components

Print with confidence using FormFutura PEI filament for demanding technical parts that require heat resistance structural strength and compliance with strict safety standards.
