PPSF for Fortus 3D Production Systems

ppsf materialPPSF/PPSU (polyphenylsulfone) material has the greatest heat and chemical resistance of all Fortus materials – ideal for aerospace, automotive and medical applications. PPSF parts manufactured on Fortus® 3D Production Systems are not only mechanically superior, but also dimensionally accurate, to better predict end-product performance. Users can also sterilize PPSF via steam autoclave, EtO sterilization, plasma sterilization, chemical sterilization and radiation*. PPSF gives you the ability to manufacture Real PartsTM direct from digital files that are ideal for conceptual modeling, functional prototyping, manufacturing tools, and end-use-parts.

The information presented are typical values intended for reference and comparison purposes only. They should not be used for design specifications or quality control purposes. End-use material performance can be impacted (+/-) by, but not limited to, part design, end-use conditions, test conditions, color etc. Actual values will vary with build conditions. Product specifications are subject to change without notice.

1 Build orientation is on side long edge.
2 Literature value unless otherwise noted.
3 Due to amorphous nature, material does not display a melting point.
4 All Electrical Property values were generated from the average of test plaques built with default part density (sparse). Test plaques were 4.0 x 4.0 x 0.1 inches (102 x 102 x 2.5 mm) and were built both in the flat and vertical orientation.
5 Test results based on Stress Crack Resistance (24-hour immersion @ 23°C and @ 100°C).
6 0.013 inch (0.330 mm) layer thickness not available on Fortus 900mc.
