Special Issue Information
Dear Colleagues,
Wire Arc Additive Manufacturing (WAAM), also called Wire Arc Directed Energy Deposition (WA-DED), is an emerging alternative to traditional forging and casting methods for producing large metallic components. With its ability to achieve high deposition rates and utilize cost-effective feedstock, WA-DED offers an efficient solution for large-scale manufacturing. We invite researchers to contribute articles focusing on the following topics:
- Comparisons of arc processes, in situ enhancements, and defect reduction techniques.
- Strategies for material efficiency and advanced control systems to improve precision and mechanical performance.
- Microstructural heterogeneity, anisotropy with build height, and tensile properties at various locations.
- Mechanical testing under aerospace-relevant conditions.
- Economic and lifecycle assessments of WA-DED tools and processes.
- Insights into defect distribution and customized equipment design for WA-DED.
We welcome innovative research that advances WA-DED technologies and applications for large-scale manufacturing.
Prof. Dr. Paul Kah

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 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 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.
