PSU Filament

Polysulfone (PSU) is an amorphous high-temp polymer that offer exceptional thermal and chemical resistance.  PSU has a Tg of 185°C, which makes it one of the highest thermally stable materials in the 3D industry.  

High-Temp Reels:  We use reels made using PC/ABS and PC for our high-temp materials.  This allows you to dry them out at higher temps once the filament absorbs moisture (which will happen to everyone eventually).  The 250g and 500g reel are made using Polycarbonate (PC) and can be dried at 135°C if the filament gets wet.  The 1kg reel is made using PC/ABS and can be safely dried at 115°C when it becomes necessary.
