Ultrafuse® 17-4 PH
The Filament Enabling Stainless Steel Parts for Applications that Require High Hardness and Mechanical Strength
Ultrafuse® 17-4 PH is a filament for the production of metal components in 17-4 stainless steel on standard Fused Filament Fabrication (FFF) printers.

Description
This stainless steel can be fully heat treated to high levels of strength and hardness. It is therefore ideal for Petrochemistry, Aerospace, and the Automotive. Parts printed with our metal-polymer composite filament Ultrafuse® 17-4 PH obtain their final properties through a catalytic debinding and sintering process known from traditional Metal Injection Molding.

Process at a Glance

PRINTING
Following our Print Preparation Checklist, Recommended Printer Parameters, and 3D Modelling Guidelines ensures your FFF printer extrudes Ultrafuse® Metal Filament and Support Layer accurately, laying the foundation for successful metal parts.
GREEN PART
3D prints made with Ultrafuse® 316L and Ultrafuse® 17-4 PH are known as “green parts,” consisting of metallic powder and polymeric binder.
DEBINDING
Debinding is a crucial post-processing step that removes the polymer binder from green parts. This prevents deformation during sintering and improves sintering efficiency.
BROWN PART
After debinding, the parts are referred to as “brown parts.” At this stage, the polymer binder has been completely removed, leaving a porous structure of metallic powder.
SINTERING
Sintering, the final step, fuses the metallic particles together, resulting in a fully metallic part known as a “white part.”
METAL PART
The all-metal “white part” can then be post-processed just like any conventional metal part, offering the flexibility to meet various application requirements.
