Special Issue Information
Dear Colleagues,
Additive manufacturing processes by laser micro-fusion on a powder bed now open the door to new degrees of freedom, both in terms of part design and in terms of reducing tooling costs or choosing materials. With the starting material being metal powder atomized with gas, its origin and its size are parameters to be taken into account in relation to the conditions of implementation on the machines. For identical operating parameters, this study aims to compare the characteristics of parts produced with two different powder granulometries coming from two different manufacturers. At the same time, the results obtained with two different laser micro-fusion machines will also be presented.
The characterization of the parts will be done from the control samples serving as a reference. The properties measured will be: the roughness, the metallographic structure showing the metallurgical health of the parts as well as the porosity rate. Finally, the development of standardized tensile specimens will complete this study. Based on the literature, a comparison will of course be made with the same similar alloy but transformed on other machines. Finally, a comparison will be made with the properties of the same material produced with conventional processes.

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.
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.
