Description

Ultrafuse® 316L is engineered for seamless use on conventional Fused Filament Fabrication (FFF) 3D printers, offering a cost-effective and straightforward solution for creating high-quality metal parts. This advanced filament combines design freedom with a lower total cost of ownership, making metal 3D printing faster, easier, and more affordable.

The final properties of printed parts, including hardness and strength, are achieved through a catalytic debinding and sintering process. This industry-standard process, initially developed and introduced by BASF, enables superior results while meeting Metal Injection Molding (MIM) standards.

Ultrafuse® 316L is designed to support a wide range of applications, such as tooling, jigs, fixtures, small series production, functional parts, prototypes, and even jewelry. The filament is a state-of-the-art metal-polymer composite containing approximately 90% highly-refined metal particles, combined with thermoplastic binders to ensure ease of handling.

Thanks to its non-slip surface, Ultrafuse® 316L is compatible with most Bowden or direct-drive extruders and can navigate complex filament paths with ease. Its high flexibility eliminates the need for additional drying, and the composite avoids the safety risks associated with handling fine metallic powders, ensuring an affordable, straightforward, and safe printing experience.

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.
