Metal additive manufacturing (AM), also known as 3D printing (3DP), has emerged as a transformative technology that revolutionizes traditional manufacturing processes. By enabling the direct fabrication of complex metal parts from digital designs, additive manufacturing offers unprecedented freedom in design and manufacturing flexibility. In this Special Issue, we seek to present a comprehensive collection of research articles, reviews, and case studies that highlight the state-of-the-art techniques, novel materials, in/ex situ materials characterization, process optimization, modelling and simulation, and applications in metal AM, with a specific focus on achieving high-performance outcomes for strategic sectors, including the aerospace, marine, automotive and energy industries. We encourage submissions that cover a wide range of topics, including, but not limited to, the following:

• Design methodologies for high-performance metal parts using AM techniques.
• Advanced metal powders and alloys tailored for AM, specifically metal matrix composites and smart alloys.
• Process optimization and control strategies to enhance mechanical, chemical and physical properties and surface finish of additively manufactured parts.
• Novel post-processing techniques for improving the performance of additively manufactured metal components, particularly in extreme environments.
• Real-world applications of high-performance metal AM in diverse sectors.

By assembling this collection of contributions, we aim to foster collaboration, knowledge exchange, and advancements in metal additive manufacturing. I invite researchers from academia and industry to share their expertise, innovative ideas, and exciting developments in this exciting field. Together, we can push the boundaries of high-performance metal additive manufacturing and pave the way for its widespread adoption.

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. Journal of Manufacturing and Materials Processing 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 1600 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.
