Product Description:

[Good printing behaviour]
PEI  filament offers significant advantages for printed parts. It is a good choice for demanding environments when PEI 9085 has reached its limit of performance.

[Lower  cost than PEEK &PEKK]3D printing PEI filament could be an alternative to PEEK or PEKK filaments if costs savings are required. This is why you will find PEI material in industries like aerospace, automotive and transportation.

[Technical support available] – we can support on how to use our material on your printer. Technical support available via E-mail:

Why PEI?
In regards of mechanical properties, flame retardance and smoke emission both Ultem filaments (Ultem 1000 and Ultem 9085 filament) are quite similar. Compared to PEI Ultem 9085, PEI filament in 1000 series has a few advantages.

In terms of heat deflection temperature Ultem 3D printer filament 1000 series shows a significant higher resistance than Ultem 9085. Although both materials are chemically resistant, Ultem 1000 series is able to resist a broader range of chemicals.
Why Yousu?

I, True manufacturer - 8+ years in 3D filament business over the world.
II, Tangle free winding to assure you high success rate of 3d printing. When you buy the roll, you can expect continuous printing without tangle issue.
