This article discusses the different forms of powder bed fusion (PBF) techniques, namely laser powder bed fusion (LPBF), electron beam powder bed fusion (EB-PBF) and large-area pulsed laser powder bed fusion (L-APBF). The challenges faced in multimetal additive manufacturing, including material compatibility, porosity, cracks, loss of alloying elements and oxide inclusions, have been extensively discussed. Solutions proposed to overcome these challenges include the optimization of printing parameters, the use of support structures, and post-processing techniques. Future research on metal composites, functionally graded materials, multi-alloy structures and materials with tailored properties are needed to address these challenges and improve the quality and reliability of the final product. The advancement of multimetal additive manufacturing can offer significant benefits for various industries.

“…[11][12][13] Most of the titanium alloys with functional gradients are prepared based on differences in materials compositions, rather than on microstructural features such as grain size. [14][15][16][17][18] However, it should be noted that due to the poor solubility of titanium in other metallic elements, it is prone to forming thermodynamically stable intermetallic phases that can affect the mechanical properties of the alloy. In this regard, a new method of preparing functional gradient structures based on the inherent microstructural differences in the material itself has been proposed.…”

“…Most existing publications have focused on the macroscopic mechanical properties of the printed multi-material parts, such as the interfacial characteristics [31,32], tensile or compressive behavior [33], and fracture toughness [27]; meanwhile, at the microscopic level, issues such as metallographic organization and element precession have also been covered [34][35][36]. Attempts are being made to clarify the scientific aspects of DED forming-'material-process (parameter)-property.'…”

Additive manufacturing provides achievability for the fabrication of bimetallic and multi-material structures; however, the material compatibility and bondability directly affect the parts’ formability and final quality. It is essential to understand the underlying printability of different material combinations based on an adapted process. Here, the printability disparities of two common and attractive material combinations (nickel- and iron-based alloys) are evaluated at the macro and micro levels via laser directed energy deposition (DED). The deposition processes were captured using in situ high-speed imaging, and the dissimilarities in melt pool features and track morphology were quantitatively investigated within specific process windows. Moreover, the microstructure diversity of the tracks and blocks processed with varied material pairs was comparatively elaborated and, complemented with the informative multi-physics modeling, the presented non-uniformity in mechanical properties (microhardness) among the heterogeneous material pairs was rationalized. The differences in melt flow induced by the unlike thermophysical properties of the material pairs and the resulting element intermixing and localized re-alloying during solidification dominate the presented dissimilarity in printability among the material combinations. This work provides an in-depth understanding of the phenomenological differences in the deposition of dissimilar materials and aims to guide more reliable DED forming of bimetallic parts.
