Arc-based Additive Manufacturing

Dear Colleagues,

Over the past few years, additive manufacturing has gained enormous attention in terms of research, and also from industry. Metallic structures, especially beam-based processes, have been extensively investigated and validated, machinery has been developed, and in many cases implemented in industrial production.

On the other hand, a large variety of arc-based processes has been used for decades to join and generate structures of various metals. Already, in the past, arc welding has been used to create components consisting either partly or entirely of weld metal, for example in the repair or tooling industries. Under the rise of additive manufacturing, several newly-named processes, based on arc welding such as Wire+Arc Additive Manufacturing (WAAM) or 3D Plasma-Metal-Deposition (3DPMD), have been introduced.

This Special Issue of Metals is devoted to the science of all arc-based additive manufacturing processes and their generated structures. These shall include wire-, strip- and powder-based variants and include topics such as design strategies, manufacturing-related issues, metallurgical details, tailored microstructures, functionally-graded structures or the investigation of properties of AM structures.

Each manuscript that contributes to form a deeper understanding of process–structure–property relationships in arc-based additive manufacturing is welcome, and we are looking forward to receiving your contributions.

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 250 words) can be sent to the Editorial Office for assessment.

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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
