Special Issue Information
Dear Colleagues,
Additive manufacturing (AM) techniques, and, in particular, the additive manufacturing of metals and alloys, are now widely studied and used, allowing for the production of highly complex mechanical parts. Additive manufacturing is playing an increasingly central role in industrial production, particularly in certain fields such as automotive, biomedical, aerospace, and electronics, thanks to the possibility of customizing the shape and mechanical properties of the component. However, AM processes are affected by high variability in the mechanical properties obtained, which are strictly related to the process parameters and the printing technologies.
In fact, depending on the process parameters, the component can be affected by poor surface quality and numerous defects (such as porosity, inclusions, and failed fusion defects). The microstructure is equally influenced by the manufacturing process, which leads to inhomogeneous and anisotropic characteristics. All these aspects influence the mechanical properties of the final component, especially the fatigue resistance, which is strongly dependent on the presence of defects in the material.
To overcome these challenges, research and development in AM materials is essential. Innovations such as new binders, improvements in post-processing techniques, and the development of advanced materials could help mitigate many of these problems, broadening applications and improving the quality of products made with additive manufacturing.
This Special Issue aims to collect original studies on the mechanical characterization of AM metals and alloys, presenting experimental results of mechanical and physical properties in relation to process parameters and microstructural defects. Articles that compare the mechanical properties of AM metals and alloys obtained with different parameters and printing technologies are highly appreciated.

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. Materials is an international peer-reviewed open access semimonthly 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.
