PPSU (Polyphenylsulfone) is an amorphous ultra-performance filament based on sulfone polymer from Solvay. PPSU has a glass transition temperature of 220°C. Parts printed with PPSU filament can operate in temperatures up to 180°C. It is resistant against most common automotive fluids. It also is designed to meet the UL 94 V-0 standards with low smoke evolution and low smoke toxicity, making the filament extremely suitable for automotive applications.

The material is qualified for unlimited steam sterilization through EtO gas, radiation, steam autoclaving, plasma, dry heat and cold sterilization. These are ideal characteristics for usage in the medical industry. The material also meets the  ISO10993 standards for medical applications.

PPSU offers a better impact resistance and chemical resistance compared to regular PEI filaments.

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.
