| Abstract Scope |
In this study, a novel multi-material powder binning method was implemented in laser powder bed fusion (L-PBF) machine. This innovative approach involves dividing the powder material into discrete regions that remain separated during the powder spreading process. Thus, by using this technique, it is possible to rapidly screen various combinations of material composition with additive manufacturing (AM) suitable deposition parameters. Furthermore, this method allows for the creation of spatially graded structures or components with multi-material interfaces. The effectiveness of this approach was demonstrated using an EOS M290 L-PBF machine to print range of materials including Steel (1018, 316, 17-4), Cobalt-Chrome (Co-Cr), and Nickel-based (Ni) alloys. Further, validation of above-mentioned concept on Cu-based alloys was established using Alpha 140 PBF platform. Tensile testing of multi-material interfaces was also carried out to relate deposition conditions to interfacial strength. Lastly, proof-of-concept parts for target applications using the multi-material binning approach are provided. |
