Through its Zetamix brand, Nanoe, headquartered in Ballainvilliers, France, has announced a new stainless steel 316L filament for the metal Additive Manufacturing market. An update on its previous version, the new filament is said to have an improved formulation with a much simpler post-processing method.

The filament is currently undergoing beta testing with the Royal Dutch Navy, which is using it for helmet supports, and precision parts manufacturer MGB, which is testing industrial lubrication nozzles.

“Our philosophy is to offer a user friendly system that sets us apart from the expensive and complicated options available in the market,” stated Guillaume de Calan, CEO. “Unlike other solutions that require post-processing by a service provider, our system enables users to easily print stainless steel in house.”

The new filament is said to enable users achieve greater dimensional accuracy, allowing the additive manufacturing of larger parts and parts with more overhangs. Unlike the previous 316L stainless steel formulation – which required sintering under pure hydrogen in a specific type of furnace – this new filament can be sintered under a wide variety of furnaces, including the Zetasinter furnace distributed by the Zetamix brand.

To achieve a density greater than 90%, this new filament must be chemically debound and sintered in a 2.5% hydrogenated argon atmosphere, allowing it to be processed in a wider variety of furnaces, including Zetamix’s Zetasinter.

This development makes the filament more accessible to all laboratories and industries in need of 316L parts, and makes it directly usable by the various laboratories, companies, and institutions equipped with a suitable furnace.
