Multi-material additive manufacturing

Abstract

A framework consisting of thermodynamic and kinetic microstructure modeling, finite element process modeling, arc melter experiments, and 𝐃𝐄𝐃 𝐞𝐱𝐩𝐞𝐫𝐢𝐦𝐞𝐧𝐭𝐬 has been developed to assist material design and process optimization. The framework is demonstrated on multi-material structures produced using the Meltio DED system at SINTEF Manufacturing, with examples of joining dissimilar metals (stainless steel 316LSi, Inconel 625, and aluminum alloy AA4043).
In addition to describing the tools in the framework, the presentation will include microstructures of the achieved multi-material interfaces, and 𝐡𝐨𝐰 𝐭𝐨 𝐢𝐦𝐩𝐥𝐞𝐦𝐞𝐧𝐭 𝐭𝐡𝐞 𝐭𝐨𝐨𝐥𝐬 𝐢𝐧 𝐚𝐧 𝐢𝐧𝐝𝐮𝐬𝐭𝐫𝐢𝐚𝐥 𝐬𝐞𝐭𝐭𝐢𝐧𝐠
