How to print with Ultrafuse 17-4 PH

A stainless steel solution for high mechanical stress and corrosive applications






Note: To use 17-4 PH filament you will have to install the Hotend M. Printing Ultrafuse 316L and 17-4 PH with a standard nozzle will seriously damage the hotend.

Ultrafuse 17-4 PH is a filament of hardened stainless steel composite with chromium-copper martensitic precipitation. It's magnetic and fully heat treatable to get high levels of strength and hardness, maintaining its mechanical and corrosion resistance at temperatures up to 315°C.

Parts printed with Ultrafuse 17-4 PH filament obtain their final full metal properties via a debinding and sintering process.

Example Applications:

  • Tooling
  • Jigs and fixtures
  • Series production
  • Functional parts and prototypes

17-4 PH parts are ideal for the Petrochemical, Aerospace, Automotive, and Medical industries. 

You can purchase 17-4 PH from our online store: Ultrafuse 17-4 PH.

Note: BCN3D Lab develops specific configurations for each material and printer. Make sure to use the last BCN3D Stratos version.

Build plate adhesion

Clean the glass before printing and apply a fine and even layer of Magigoo Pro Metal glue to achieve good adhesion between the 3D printed part and the printing surface of your 3D printer in order to keep the part fixed.

It is best to apply Magigoo when the printing bed is cool.

Use the Mesh Mapping to ensure that the model is properly attached to the build plate, to get the best result on the debinding and sintering process.



This filament doesn't absorb humidity from the air. However if the material is not in use for extended periods of time, it is recommended to keep the 17-4 PH spools in a box or airtight container.

Filament Storage

17-4 PH emits low levels of fumes and particles when printed. We recommend printing it in a well-ventilated area to ensure a healthy environment.
