Additive manufacturing of titanium components: An up-date

This paper is an up-date of a paper published in Metal Powder Report almost two years ago (Dutta and (Sam) Froes, 2017). The present paper presents the various methods which have been developed for the production of AM components, emphasizing those which have been used for titanium parts. This is followed by a presentation of recently developed processes for the production of spherical powder feed-stock for Additive Manufacturing including an innovative low cost non-melt approach. Consideration is then given to the effects of surface roughness and defects of AM parts. A summary of some of the titanium parts which have been fabricated by AM in the past few years in a variety of segments of the economy is then discussed.
