Magnetohydrodynamic principle of 3$D$-printing for non-ferrous metal melts

The new principle of high-effective 3D-printing for liquid non-ferrous metals has been suggested. Electric current applies to the flow of liquid metal creates Ampere's forces that increases pressure in the lowest part of this flow. Increased pressure causes raising of crystallisation temperature. The principal possibility of this process with regard to additional heating caused by this electric current has been investigated. It has been found that addition of ferromagnetic supplements could create parameters range wherein crystallization process is possible.
