Special Issue Information
Dear Colleagues,
Additive manufacturing (AM) and three-dimensional (3D) printing, based on the innovational principle of the incremental addition of a material to build a part directly in its final or near-final geometry, have been accelerating the development of advanced manufacturing technologies. Metal AM has seen great industrial adoption and maturation, especially in the aerospace and medical fields. Currently, metal AM methods are mainly divided into laser-based, electron beam-based, and arc-based AM technologies according to the heat source type. High-energy beam-based AM, due to its high energy density and rapid heating/cooling nature, can produce an ultrahigh temperature gradient within a mesoscale molten pool and a huge solidification rate. As a result, a non-equilibrium metastable microstructure and attendant unique physical or chemical properties can be formed. In recent years, after the long-term contribution of metal AM research in improving component densification and forming quality, it has entered a new stage of development where more attention is being paid to the enhancement and breakthrough of mechanical properties and the functionalization of components. At present, this work has gradually developed several prominent research hotspots including the multi-scale modeling and in situ monitoring of AM process, AM of nanoparticle-reinforced metal matrix composites, AM of graded functional materials, innovation design and the AM of function-driven porous structures, etc.
In this Special Issue, we welcome articles that focus on the novel designs, metallurgical process controls, property characterizations and particular applications of additive manufactured metals. High-performance functional materials developed using metal AM methods are of special interest, with a high implementation potential in functionality programming that allows the production of highly adaptable functional metal parts.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.
