How does metal FFF 3D printing work?

Metal FFF printing extrudes filament loaded with metal powder in a polymer binder, producing a green part that is then debound and sintered in a furnace to become a solid metal component.

Is metal FFF cheaper than traditional metal 3D printing?

Metal FFF systems, such as those from Markforged, are generally more affordable to buy and operate than powder-bed metal printers, though they typically require a secondary furnace.

What metals can be printed with metal FFF?

Common metal FFF materials include stainless steel, tool steel and copper, with the choice depending on the mechanical, thermal or conductive properties the part needs.

What is the shrinkage rate for metal FFF parts?

Sintered metal FFF parts typically shrink by around 15 to 20 percent from the printed green part, and this is accounted for automatically in the printer's software during file preparation.

It’s a simple, accessible path to producing strong, functional stainless-steel parts without compromising on precision or durability. Perfect for prototyping, tooling and short-run production, these filaments bring metal capabilities to your desktop or production floor.
