Abstract
The main problems of the development of 3D printers for machine engineering are related to low rate of printing and low quality of fabricated items. The problems can be solved using a new principle of high-efficiency 3D printing for steel melt based on the compression of the melt jet by magnetic field of flowing current and an increase in the crystallization temperature. Under certain conditions, the heat liberation of current can be compensated for using alternative processes. Ranges of parameters at which the effect can be implemented are determined.

Notes
Strictly speaking, the distribution of the current density over the cross section of the jet is determined from the condition for energy minimization. However, the corresponding estimation leads to a correction by a constant factor of about unity.
