FormFutura® PPSU

About The Materials 

PPSU is an ultra-performance 3D printer filament that can be used to 3D print parts for demanding applications that are chemical resistant and can operate in temperatures up to 180°C.

Materials Documentations

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.

*) 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
