Ultrafuse 17-4 PH

High mechanical strength/ hardened/ corrosion resistance


Ultrafuse 17-4PH is an FFF 3D printing filament composed of 90% by weight of sinterable 17-4PH steel powder and 10% binder polymers, developed specifically to facilitate the extrusion of this material. This steel can be hardened through precipitation to achieve superior strength and hardness. Compared to 316L steel, it has higher mechanical properties at the cost of lower corrosion resistance.

Stainless Steel 17-4 PH® provides an outstanding combination of high strength, good corrosion resistance, good mechanical properties at temperatures up to 316°C, and good toughness in both base metal and welds. Quick, low-temperature heat treatments minimize distortion and scaling. This alloy is widely used in the aerospace, biomedical tools, chemical, petrochemical, food processing, paper, and general metalworking industries.

Bed adhesion:

To ensure good bed adhesion use Magigoo.


  • Only compatible with BCN3D Epsilon when paired with the Hotend M.
  • Feed it cautiously into the machine.
  • Once the part is printed, remove carefully the piece to avoid chipping the part. The removal of the object is easier if you just apply water on the glass.
