BASFUltrafuse® 316L

Stainless Steel Composite Metal Filament for 3D Printers

Ultrafuse® 316L is an innovative filament to produce 316L grade stainless steel parts.

Easy and cost effective 3D printing of metal parts with Ultrafuse® 316L

BASF 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.
