Development of technological basis of 3D printing with highly filled metal-poly-dimensional compositions for manufacture of metal products of complex shape

Abstract

This article discusses the possibilities of obtaining “green” parts by the FDM (Fused deposition modeling) method from ready-made polymer-metal compositions used in the MIM (Metal Injection Molding) technology and the technology of obtaining functional metal products of complex shape and structure. The influence of technological parameters of 3D printing on the quality of parts (presence of defects) obtained by highly filled polymers has been established. Thermogravimetric analysis was carried out to determine the melting point without changing the composition of the material. A filament was fabricated from granular feedstock material catamold 316L using the FDM technique.
