Recent Advances in Multi-Material Metal Additive Manufacturing

Dear Colleagues,

As the Guest Editor for the Journal of Manufacturing and Materials Processing, I am pleased to announce a Special Issue on the Recent Advances in Multi-Material Metal Additive Manufacturing (AM). Over the past 30 years, metal AM has evolved rapidly in various aspects, e.g., productivity and part quality. Many industrial sectors have started to adopt AM due to the unique capabilities that AM can offer. But almost with no exception, the application space of the metal AM technologies has been limited to single-material components. On the one hand, it is the technical difficulties, e.g., deposition method and material compatibility, that have slowed down the advancement of multi-material AM; on the other hand, the lack of known applications resulted in less investments. This problem will be solved as multi-material AM becomes more accessible and the meso-scale design starts to be incorporated into the design philosophy.

For this Special Issue, researchers are encouraged to submit their novel studies which address the challenges specifically in multi-material metal AM, including but not limited to:

1. Design optimization;
2. Feedstock delivery methods;
3. Machine and laser control;
4. Scan strategy optimization;
5. Printing parameter optimization;
6. Process monitoring;
7. Characteristics of the multi-material interface;
8. Defect formation mechanisms;
9. Material compatibility;
10. Alloy discovery;
11. Post-processing treatments;
12. Microstructural characteristics;
13. Mechanical performance;
14. Novel multi-material testing methods.

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 1800 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.
