Metal-Based Additive Manufacturing: Processes, Characterization and Applications

Dear Colleagues,

Additive Manufacturing (AM) represents a paradigm shift in how metallic, ceramic, and polymeric materials are designed, processed, and applied across industrial sectors. This Special Issue aims to gather high-quality contributions that deepen the understanding of AM process–structure–property relationships and promote the integration of AM technologies into functional and optimized designs. Topics include process parameter optimization, defect formation and control, microstructural and mechanical characterization, and advanced testing of AM components. The role of Design for Additive Manufacturing (DfAM) is highlighted as a key enabler for exploiting AM’s geometric freedom, enabling lightweight structures, internal cooling channels, and topology-optimized components. Emphasis is placed on both melting and sintering-based AM routes, hybrid processes combining additive and subtractive manufacturing, and novel material systems such as high-entropy alloys, metal–ceramic composites, and functionally graded materials. Studies involving simulation, digital twins, or in situ monitoring for process prediction and control are particularly welcome. The objective is to foster a multidisciplinary discussion that supports the transition of AM from laboratory research to industrial-scale production, sustainable design, and digital manufacturing.

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.
