Magnetohydrodynamic Principle of 3D Printing for Non-Ferrous Metal Melts

Abstract

In this paper, we propose a new principle of high-performance 3D printing for non-ferrous metal melts. The crystallization temperature may increase in the lower part of the tapering jet of liquid metal due to the pressure produced by the Ampere forces caused by a specially applied current. The fundamental possibility of this crystallization with regard to additional heating produced by this current was studied. The introduction of ferromagnetic additives was found to allow creating a range of parameters in which such crystallization is possible.
