Multi-material 3D Printing: The Role of Substrate-based Synthesis
DOI: 10.22184/1993-7296.FRos.2025.19.6.428.442
Multimaterial 3D printing by the substrate-based synthesis (SBS) method is a promising approach to obtain the products with the locally variable properties. However, the processing limits associated with various differences in the physicochemical properties of the materials being combined and the lack of a systematic classification hinder the development of this area. A new classification of multi-materials for SBS has been developed that includes three groups: homogeneous alloys (based on a single metal), dissimilar weldable alloys, and dissimilar non-weldable alloys. The features of transition zones for seven systems (VT6/VT1-0, AlSi10Mg/Al-Si-Mg-Cu, 316L/FeNi36, VZh159/BrKhTsrT V, Ti6Al4V/Inconel 718, 316L/NiTi) have been studied. It has been established that the number of defects, microstructure, and phase composition of the transition zone are determined by the type of alloy combination. The developed classification allows us to systematize the research works, optimize printing parameters, including of the laser tools, and predict any possible problems occurred when developing new multi-material systems.
