Metal Additive Manufacturing Technologies

Dear Colleagues,

At present, the global manufacturing industry is undergoing profound changes. Additive manufacturing (3D printing) technology has developed into a core technology for improving the design and manufacture of high-performance complex components, with constantly advancing engineering applications in aerospace, biomedical, energy, transportation, national defense and other fields. At present, the innovative development of metal additive manufacturing technology integrates new materials, innovative structure design, integral component manufacturing, multifunctional integration, additive manufacturing process synthesis and intelligent printing. Opportunities and challenges coexist. In the process of innovation and leapfrog development of metal additive manufacturing technology, there are many key scientific and technical problems that require further research and breakthroughs. These problems include, but are not limited to, material design and interface control problems in the transition from single-material printing to multi-material printing and from simple structure printing to multi-functional complex overall structure printing; structural design and print quality control problems; traditional trial-and-error process development and precise process control problem intelligent printing. Progress in the innovative development, technological progress and large-scale industrial application of metal additive manufacturing technology necessitates a series of new principles, methods, materials, processes and technologies.

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.
