PSU Filament

Polysulfone

B
Also known as:Polysulfone
Family:PSU

Why Use PSU?

  • Very high heat resistance (Tg ~187C) and retains strength near that range
  • Resists water/radiation/chemicals; can be sterilized
  • Enables 'citizen science' type projects

Things to Consider

  • Often nylon is a better overall choice unless you need the heat/sterilization envelope
