Progress and Challenges towards Additive Manufacturing of Structural Materials

Dear Colleagues,

Additive manufacturing (AM) holds significant potential for the fabrication of structural materials, yet it faces significant challenges within the current methodologies such as laser powder bed fusion (LPBF), directed energy deposition (DED), and additive friction stir deposition (AFSD). Issues including hot cracks, porosity, residual stresses, and microstructural defects hinder industrial application. Furthermore, material selection and optimization complexities necessitate a deeper understanding. This Special Issue aims to highlight both progress and challenges in AM methods. Contributions exploring process optimization, materials development, and performance characterization are invited. We especially welcome practical studies on defect formation mechanisms and mitigation strategies. Theoretical modeling and simulation studies predicting and optimizing AM outcomes are vital for progress. These theoretical methods aid in speeding up material development and enhancing our understanding of AM technology. Therefore, we welcome contributions that expand knowledge in this area.

We eagerly await your contributions.

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.
