Nadir is pleased to announce the new line of filaments NaMEX for 3D printing intended for indirect metal additive manufacturing by Material Extrusion Additive Manufacturing of Metal (Metal-MEX). This is an emerging technology to manufacture full-metal object alternative to direct metal AM methods like powder bed fusion (PBF) and direct energy deposition (DED) or other indirect approaches like binder jet printing (BJP).
The main advantages of this approach to metal additive manufacturing are that it requires low tech equipment (FDM printer and debinding-sintering station) and it does not employ free flowing metallic powder.
Two products are now available containing soft iron (NaMEX-Fe) and copper (NaMEX-Cu) respectively, compounded with a proprietary binder formulation able to overcome the brittleness of filaments containing high level of powder (more than 50 % v/v) removing the risk of print failure due to filament break during the extruder feeding. In addition to these products, Nadir could use this technology to produce custom filaments using metallic powder selected on the basis of customer requirements.
NaMEX-Fe filament has been used by researchers of University of Pisa to manufacture a soft ferromagnetic component for Hall thruster magnetic circuit to be used as space propulsion, read the article here.
