Firewire® PPSF (PPSU) 3D Printing Filament
Polyphenylsulfone (PPSF or PPSU) is a high-temperature aromatic sulfone polymer. Long considered to be one of the highest performance polymers in the plastics world. PPSF has excellent thermal and chemical resistance, making it well suited for demanding applications in automotive, aerospace, electronics, defense, industrial, medical, semi-con applications. Previously only available to Stratasys® customers - now you can print with this ultra performance polymer.
Firewire® is 3DXTECH's brand of high-temperature polymers designed specifically for 3D printing the highest performance parts possible. PPSU is sold using names such as Solvay's Radel R and BASF's Ultrason P.
Attributes of Firewire® Polyphenylsulfone PPSF (PPSU) include:
- Very high thermal properties with a Tg of 220°C and HDT of 205°C
- Excellent hydrolytic resistance
- High Environmental Stress Crack Resistance (ESCR)

Annealing Printed Parts: If needed, PPSF parts printed on an open source / desktop 3D printer may be annealed in a hot-air oven to reduce any printed-in stresses that may be present in the part. Printed-in stresses may occur in any plastic and may result in lower than expected mechanical properties. If this is an issue with your part, then you can follow the simple 5-step ramp up/down process for annealing your parts.
Step 1: Place printed parts in cool, room-temp oven.
Step 2. Set temp to 300°F and allow to stabilize for 1 hour.
Step 2: After 1 hour at 300°F, increase oven temp to 400°F and allow to stabilize 1 additional hour.
Step 3: After 1 hour at 400°F, reduce heat back to 300°F and allow to stabilize for 30 minutes.
Step 4: After 30 minutes, turn off oven heat and allow printed parts to return to room temp inside the oven as it cools.
