Design of dissimilar material joint for defect-free multi-material additive manufacturing via laser-directed energy deposition Summary: • This study aims to optimize the shape of interface geometry between the dissimilar materials, ensuring a defect free joint, and develop functional designs that mechanically interlock 2 dissimilar materials through InssTek's MX-Lab. • In this study, AISI 316L stainless steel and Inconel 625 (Nickel alloy) were joined into various structures using the LDED. •And tensile test was chosen to evaluate the performance of the various designs. This test is conducted to assess the structural characteristics and performance of both the V-type and anchor joints. • The results indicate that the specimens demonstrate varied mechanical properties due to the influence of lamination direction and order, which affect the formation of critical cracks and pores. •It is expected that the same improvement can be obtained when the developed strategy is applied on other joints which connect other alloys combinations.

Summary: • This study highlights the advanced capabilities of AM with InssTek's DED Technology, and explores key factors influencing the joint quality of multi-material components for various applications. • Combination of IN718 and SS316L, various deposition angles for material interfaces, ranging from horizontal to vertical directions, were explored. In the combination of IN625 and 42C steel, horizontal deposition with varying sequences of material deposition was employed. And Metallographic as well as mechanical properties investigations were carried out. • The research demonstrates that factors like deposition order, interface orientation, and surface quality significantly influence the structural integrity and mechanical properties of materials. • In many industrial applications, single-material components struggle to meet all operational demands, necessitating the development of multi-material components. This allows for simple and safe assembly.

Test Result of C103(Nb Alloy) Powder Recycling for LP-DED

Following the introduction of our conference presentation ( https://lnkd.in/gRZRQAFv ), We are sharing the test results for C103 Powder Recycling. C103 is attracting attention in various industries such as aerospace and energy for its excellent mechanical properties, but its use was limited due to its high price. InssTek is researching powder recycling to reduce costs and broaden its industrial applications. Powder - The analysis of powder recycling results indicates that powders recovered in an argon environment can be reused in LP-DED process. - However, prior to reuse, a sieving process is deemed essential. LP-DEDed Specimen - 3D printed specimens using recycled powder confirm that powders recovered and recycled in an argon atmosphere exhibit performance comparable to that of virgin powder, meeting ASTM standards and thereby validating their potential for reuse. - Although recycling environment is important, test results show that printing environment is more critical factor affecting mechanical properties.
