“…Mussatto 18 has developed a dual powder box selective powder dispersion device and successfully applied it to SLM additive manufacturing process for heterogeneous material parts. The working principle of this device is based on the use of a point by point controlled micro airflow to attract powder particles onto a cylindrical sieve, which forms the same powder pattern as the model slice.…”

In order to manufacture non-ferromagnetic heterogeneous material by Selective Laser Melting (SLM), it is necessary to solve the separation problem of non-ferromagnetic mixed powders after SLM forming. This research presents how to resolve this problem using TiNi/Ta mixed powders by ultrasonic vibration screening method and the analysis of SLM manufacturing experiment for non-ferromagnetic heterogeneous material. The purity of TiNi and Ta powders after separation could reach 99.7087%wt% and 98.8501wt% respectively, which both reached a relatively high purity. A TiNi alloy sample with Ta coating and TiNi/Ta gradient transition was manufactured successfully by SLM. The material interface of the sample achieves metallurgical bonding, and the color of the sample profile shows a gradient transition. The EDS analysis shows that the material composition changes from Ta ->Ta/TiNi gradient ->TiNi from surface to inside of the sample. The Ta coating contains over 92.5wt% Ta, and the TiNi matrix contains over 98.69wt% TiNi. Along the powder laying direction, it is difficult to clean the small powder near the solid-powder or solid-solid interfaces made of two different materials, which causes micro polluted areas near the interfaces. This study also provides a new method for integrated manufacturing of TiNi alloy part with Ta coating.

“…Laser-Powder Bed Fusion (L-PBF) is an additive manufacturing process that is advancing in the production of multi-material metallic structures with complex geometries [4,5]. However, the fabrication of multi-material parts using L-PBF is a challenging task because it requires the deposition of two or more powders in a layer-by-layer fashion [6][7][8][9][10]. This can be achieved using machines specifically designed to process powders of different materials while processing the same layer [4,9,11].…”

In this work, a systematic study was conducted on the fabrication of multi-material components obtained employing Laser-Powder Bed Fusion (L-PBF) technology. The idea of making multi-material components is a winning capability of additive technologies because it allows the fabrication of Functionally Graded Materials (FGMs) with the customization of parts according to different required properties. The transition from one material to another was achieved gradually and continuously within the same layer using ad-hoc equipment designed for L-PBF systems with a powder spreading technique based on coaters or rollers. The influence of the relative position of the different materials within the powder chamber and the geometry of the developed equipment on the metallurgical and mechanical properties of the manufactured samples was evaluated. The performed tests involved the use of two materials, a nickel-based superalloy, and a stainless steel, having different chemical, physical and mechanical properties to obtain gradual properties variation in the manufactured samples. Based on the results of post-process characterization obtained through metallographic, chemical, and mechanical analysis, the relative positions of the materials and the geometry of the developed equipment have a limited effect on the sample’s manufactured properties. The characteristics of the FGM zone depend on the nature of the employed powders, and its extent coincides with that defined during the design of the divider.

“…However, due to recent advances in PBF-LB equipment technology, it is now possible to process different materials in one component [17]. Powder Bed Fusion by Laser Beam using Multi-materials (PBF-LB/MM) expands the degrees of freedom of AM by another dimension and enables the ideal adaptation of the shape to application-specific requirements, but also offers the possibility of locally using the material with the ideal material parameters for the intended application [5].…”

“…The conventional deposition, in which a single blade or brush is used to distribute the powder over the substrate plate, is not suitable for 3D MM applications. Different concepts were compared by Schneck [18] and Mussatto [17]. They are based on vibrating nozzles [19][20][21], a suction operation between different material coatings [18,22], the use of multiple powder hoppers [23,24], pressurized patterning drums [25] and an electrophotographic powder deposition [26,27].…”
