Special Issue Information
Dear Colleagues,
Laser metal additive manufacturing and laser welding are core technologies in materials and manufacturing, offering broad application prospects in the aerospace, automotive, and biomedical industries, among others. This Special Issue will provide a platform for high-quality, cutting-edge research in this field, addressing topics such as process optimization, in-process monitoring, material property control, numerical simulation, and engineering applications. We welcome submissions of original research papers, review articles, and case studies that will advance the innovation and industrial application of laser-based additive manufacturing and welding technologies.
- Process Development and Optimization: Novel laser processing techniques, parameter optimization for diverse alloys (e.g., titanium, aluminum, high-entropy alloys, metallic glasses, and superalloys), and strategies for defect mitigation (porosity, cracking, and delamination).
- Microstructural Evolution and Mechanical Properties: In situ characterization of phase transformations, grain growth, texture development, and their correlation with mechanical performance under service conditions.
- In Situ Monitoring and Intelligent Manufacturing: Real-time sensing, closed-loop control, and machine learning/AI-driven process optimization for enhanced reproducibility and quality.
- Multi-Physics Modeling and Simulation: Numerical models (thermo-mechanical, fluid flow, phase-field) to predict and optimize process outcomes, reduce trial and error, and guide experimental design.
- Industrial Applications and Case Studies: Real-world implementations in aerospace (e.g., turbine blades), automotive (lightweight structures), energy (fuel cells, heat exchangers), and biomedical (implants, surgical tools) applications.
- Welding and Joining of Dissimilar Metals/Composite Structures: The bonding mechanisms, interface engineering, and performance of laser-welded hybrid materials.
We encourage researchers, engineers, and practitioners worldwide to share their insights to advance the scientific understanding and technological maturity of laser metal additive manufacturing and laser welding. Both full-length research papers and critical reviews will be considered, with a focus on impactful contributions that bridge fundamental science and industrial practice.

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. Crystals 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 2100 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.
