Recent Progress and Scientific Challenges in Laser-Based Additive Manufacturing

Dear Colleagues,

We invite you to submit your research for this Special Issue of the Journal of Manufacturing and Materials Processing titled “Recent Progress and Scientific Challenges in Laser-Based Additive Manufacturing”. Recent advances in laser generation and delivery systems, process monitoring and zero-defect manufacturing are directing current research on more efficient and cost-effective novel manufacturing. Additionally, the growing demand for organically and free-form designed components requires high process agility and productivity—capabilities typically offered by laser-based additive manufacturing (AM) systems. However, challenges remain in achieving defect-free and near net-shape components using laser-based AM. These include issues such as pore and crack formation, layer height consistency, gas content control, residual stress management, and microstructure optimisation. Therefore, there is a significant need for experimentation, analysis, and simulation to formulate and evaluate theories for addressing these new processes and materials.

In this Special Issue, we invite you to submit your fundamental and applied research on novelty in laser-based AM processes, uncovering the mechanics, computational analysis, process development, the characterisation of the process, and process monitoring and analysis using smart systems, machine learning (AI), and data analytics. Studies should include either theoretical, numerical, or experimental approaches, either separately or in combination, to provide solutions to these challenges.

We encourage you to submit studies covering these research areas:

• Material testing and characterisation;
• Sub-specimen characterisation;
• Testing of additively manufactured materials;
• Defects in high-strength material AM;
• Limits in material processing;
• Beam shaping and multi-source effects;
• Constitutive modeling;
• Multiscale/multiphase simulations;
• Dynamic testing and impact analysis;
• Process monitoring, optimisation, and control;
• Machine learning for AM;
• Data-driven manufacturing.

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.
