MetalFil -  is a metal-filled PLA-based filament with approximately 80% of gravimetric copper filling. This incredible high filling with copper powders enables every FDM 3D printer user to 3D print copper objects which are almost indistinguishable from genuine copper casted objects. 
MetalFil is easy to print and can be printed on full metal, PEEK, and PFTE hotends and can perfectly be printed with ≥ 0.4mm nozzles with retraction settings enabled on both direct drive extruders, as well as on Bowden style extruders, which is a truly unique feature for a metal-filled filament. MetalFil printed objects can very easily be post-processed allowing one to create amazing copper objects with various patina effects.
