We have developed Ultrafuse® 316L to realise high-quality metal parts and high throughput. This state-of-the-art metal filament is suitable for use with any conventional Fused Filament Fabrication (FFF) printer. Following the print, the final properties of the part are then achieved through a debinding and sintering process developed by BASF, which has emerged as the industry standard.
Ultrafuse® 316L is cost-effective, easy to process and meets the MIM industry standard for catalytic debinding and sintering. This innovative industry-grade metal-polymer composite supports a broad range of applications, including tooling, jigs and fixtures, small series production, functional parts, prototypes, and even jewellery.
Ultrafuse® 316L formulates thermoplastic binders with 90 mass percent of highly-refined metal particles. Our filament has a non-slip surface allowing it to be applied in most Bowden or direct-drive extruders. Thanks to its high flexibility, it can be fed through complex idler pulleys and multiple filament transportation systems in printers – no extra drying required. As a filament, the metal-polymer composite comes with none of the occupational and safety hazards associated with the handling of fine metallic powders, making 3D printing of stainless-steel parts affordable, straightforward, and safe.

Designed for secure and easy handling on conventional, open-material Fused Filament Fabrication (FFF) printers, Ultrafuse® 316L comes with a wide processing window. To help you succeed in 3D printing metal parts we provide printer processing guidelines including Ultrafuse® 316L parameter sets. In addition, consultancy and on-site support are available to help ensure the material performs on your printer.
