FormFutura PPSU (Polyphenylsulfone) is an amorphous ultra-performance 3D printing filament
based on sulfone polymer from Solvay. PPSU has a glass transition temperature of 220°C and
3D printed parts with PPSU filament can operate in temperatures up to 180°C. This makes PPSU
extremely suitable for automotive applications around the engine and cylinder block as PPSU is
resistant against most common automotive fluids. PPSU filament is also perfect for 3D printing
medical applications as 3D printed parts with PPSU filament are qualified for unlimited steam
sterilization through among others  EtO gas, radiation, steam autoclaving, plasma, dry heat and
cold sterilization. FormFutura PPSU meets the  ISO10993 standards for medical applications.
PPSU offers a better impact resistance and chemical resistance compared to PEI and is inherently
flame retardant to UL 94 V-0 standards with low smoke evolution and low smoke toxicity.

General printing guidelines *

*) Above displayed settings are meant as guidance to find your optimal print settings.
These ranges in settings should work for most printers, but please do feel free to experiment
outside these parameters if you think it is suitable for your printer. There are a lot of different
type of printers, hot-ends and printer offset that it is extremely difficult to give an overall one-size-fits-all setting.
