It is designed for ultimate ease of handling on conventional Fused Filament Fabrication 3D printers. BASF Ultrafuse® 316L combines greater freedom of design with a lower total cost of ownership – printing metal parts easier, faster and affordable. Parts printed with Ultrafuse® 316L obtain their final properties, including hardness and strength, through the catalytic debinding and sintering process. The catalytic debinding technology was developed and introduced by BASF and has emerged as the industry standard.

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

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 around 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.

Which 3D printers should I use with Ultrafuse® 316L?

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.
