Layer-by-layer forming of metal structures and elements of various-purpose mechanisms is a promising venue of development of high technologies. Broad possibilities for optimization of technology parameters and accuracy of positioning the forming layers allow manufacturing thin-wall products of different geometry. Moreover, dissimilar structures can be produced by changing the filler material. Such a technological process requires thorough optimization of the respective technology cycle to guarantee the required quality of the dissimilar structure, depending on product shape, materials and features of a specific technology. This work is a study of the features of the kinetics of temperature field and stress-strain state of dissimilar structures during multilayer surfacing in the case of T-beam structures, made by xBeam 3D Metal Printer technology. 12 Ref., 6 Fig.
Keywords: layer-by-layer forming, dissimilar structure, temperature field, stress-strain state, mathematical modeling
