Stainless Steel filament
Metal parts with FDM: 316L stainless steel.

What is Stainless Steel?
Ultrafuse® 316L is a stainless steel composite filament developed by BASF. Grade 316L is preferred in industrial applications and prototyping for its durability, corrosion resistance and mechanical properties. It makes it possible to produce complex metal parts with FDM.
Debinding and sintering are required after printing. TAİ Robotik takes on the 3D printing stage of the work.
- Metal
- Chemical resistant
