Abstract
Combined 3D printing technology including a combination of additive (layer-by-layer) surfacing with electrodynamic treatment of deposited layer was considered. On the basis of mathematical modeling with the use of the Prandtl-Reiss ratio, on the example of aluminium-magnesium AMg6 alloy, the influence of the shape of the indenter for electrodynamic treatment on the distribution of basic parameters and components of the stress-strained state, in particular, the size of the zone of plastic deformations and stresses, depth and width of the contact interaction zone in a metal layer interacting with a roller-indenter moving along the normal to a layer at a speed of 1, 5 and 10 m/s across the thickness of the deposited layer was studied. It was established that the use of a roller with a contact surface, having a shape of a semi-circle, leads to an almost uniform distribution of compression stresses components in the deposited layer, the values of which can reach the yield strength of AMg6 alloy. The results of mathematical modeling give reasons to recommend the use of an electrode in the form of a semicircle (EC) for the development of combined technologies of 3D printing of volumetric metal products, which consist in combination of additive surfacing (WAAM, plasma, microplasma surfacing, etc.) of a volumetric metal product with electrodynamic treatment of each deposited layer. 14 Ref., 4 Tabl., 7 Fig.
