Laser Powder Bed Fusion: Alloy Design and Material Quality Optimisation

Dear Colleagues,

We invite you to contribute to a new Special Issue focused on laser powder bed fusion (LPBF), with a special emphasis on alloy design and material quality optimisation. This collection aims to showcase the latest innovations and breakthroughs that are shaping the future of metal additive manufacturing (AM).

LPBF has emerged as a transformative technology in sectors such as aerospace, biomedical, and energy. However, its full potential hinges on the development of alloys tailored for AM and the refinement of process parameters to ensure consistency, reliability, and performance. We seek submissions that explore this critical intersection—where materials science meets process engineering.

Topics of interest include, but are not limited to, the following:

• Design and development of novel alloys for LPBF;
• Microstructural evolution and phase transformations during printing;
• Powder characteristics and their influence on build quality;
• Process parameter optimisation and defect mitigation;
• In situ monitoring, modelling, and control strategies;
• Post-processing techniques and their impact on mechanical properties;
• Data-driven approaches and machine learning in LPBF.

Contributions should aim to deepen understanding, improve manufacturability, and accelerate industrial adoption of LPBF technologies. Join us in shaping the next chapter of LPBF innovation. Submit your manuscript and be part of a collection that will inform, inspire, and advance the field.

Prof. Dr. Gregory John Gibbons

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.
