Additive Layer Manufacturing using Metal Deposition

Dear Colleagues,

Among the additive layer manufacturing techniques for metals, metal deposition techniques, including Laser Metal Deposition (LMD) (with powder or wire) and Wire Arc Additive Manufacturing (WAAM), are known as versatile, efficient, and robust processes dedicated to the fabrication of low to average complexity parts, with a higher built volume per hour than powder bed techniques. Although the LMD process is derived from the usual laser cladding techniques, it is still the object of a large number of research activities due to the increasing industrial demand for this attractive laser-based technique. Moreover, the WAAM process is currently the object of growing industrial interest.

For this reason, a Special Issue on additive layer metal deposition is proposed, including the most recent scientific developments on various topics involving novel process developments, the manufacturing of new materials, and up-to-date numerical works on the employed processes.

More in detail, this Special Issue aims to address: (1) new LMD or WAAM procedures (new wavelengths, pulsed laser regimes, dedicated instrumentations, or process controls) and the resulting effects on surface finish, microstructures, and mechanical properties; (2) the additive manufacturing of innovative metals and graded materials; (3) the mechanical (static, fatigue, wear) or corrosion behaviour of built parts; and (4) the analytical or numerical modeling of WAAM or LMD (such as the numerical optimization of powder streams and nozzles, multiphysic modeling, melt-pool hydrodynamics, and the reduction of models to address large or complex parts).

We are looking forward to receiving your most recent works on all of these topics, which render this Special Issue a highly valuable scientific contribution to the current conversation.

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.
