Recent Progress on Powder Materials for Additive Manufacturing

Dear Colleagues,

Additive manufacturing (AM) has rapidly emerged as a transformative technology, offering unique opportunities for producing complex, lightweight, and high-performance components across aerospace, automotive, biomedical, and energy sectors. Central to the success of AM processes is the development and utilization of powder materials, as powder properties directly influence processability, microstructure evolution, and final part quality. Recent advances in powder production techniques, including gas and plasma atomization, mechanical alloying, and chemical routes, have enabled the design of powders with tailored particle size distributions, surface chemistry, and flow characteristics. Simultaneously, progress in powder surface modification, coating strategies, and advanced characterization methods has provided deeper insights into powder behavior during spreading, melting, solidification, and recycling. These innovations are further supported by computational modeling and in situ monitoring, which link powder characteristics to defect formation, mechanical properties, and performance reliability of AM-fabricated parts. This proposed Special Issue of Powder, titled “Recent Progress on Powder Materials for Additive Manufacturing,” will highlight cutting-edge research on powder synthesis, surface engineering, recyclability, powder–process interactions, and structure–property relationships. By bringing together contributions from both academia and industry, the issue aims to advance powder science and accelerate the translation of novel powder technologies into reliable, scalable, and sustainable AM solutions.

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. Powders is an international peer-reviewed open access quarterly 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 1000 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.
