Additive Manufacturing: Alloy Design and Process Innovations

摘要

Additive Manufacturing (AM) is an emerging manufacturing technique of immense engineering and scientific importance and is also regarded as the technique of the future. AM can fabricate any kind of materials including metals, polymers, ceramics, composites, etc. It also offers several advantages, like added functionality, offering intricacy for free, near-net-shape fabrication with minimal or no post-processing, shorter lead time, etc. AM has been used in several industrial sectors like aerospace, automobile, oil refinery, marine, construction, food industry, jewelry, etc. However, the several shortcomings in the field of AM are (a) alloy development that suits the AM processes (b) pre-mature failure of materials, even though improved properties are observed (c) process development and innovation (d) structure-property correlation, etc.
