Abstract

Additive Manufacturing (AM) is a rapid prototyping technique extensively used to build complex structures and intricate shapes without the necessity of post process machining. This process exists for two decades and still needs to attain its growth in order to meet the commercial requirements. In this article, Laser Metal Deposition (LMD) and Selective Laser Melting (SLM) of alpha-beta titanium alloys and CP-Ti are reviewed. The reported investigations are categorized into 2 major classifications, namely:(i) Micro and macro structure and resulting mechanical properties of alpha-beta Ti and CP-Ti, (ii) Effect of process parameters. Scholarly publications on SLM and LMD of alpha-beta Ti alloys and CP-Ti are surveyed. The limitations of this emerging but promising method of manufacture are discussed.
