3D printing filament for railway parts

Zortrax says that its 3D printing process is now able to process a flame-retardant filament to make parts for railway applications.

The company’s Endureal 3D printer is now compatible with BASF’s Ultrafuse polyphenylsulfone (PPSU) filament, which is reportedly resistance to chemicals and performs well in extreme thermal conditions.

According to Zortrax, the filament complies with the European EN 45545-2 standard and has been approved for use in the manufacture of rail vehicles operating on the surface and underground. The material also complies with the UL 94 flammability standard and has a V0 flammability rating.
