Special Issue Information
Dear Colleagues,
Laser and electron beam powder bed fusion processes are prominent additive manufacturing techniques used to create complex metal parts and components from metal alloys. These processes involve melting layers of metal powder using a high-power laser or electron beam, which fuses the particles together to form a solid structure. Laser and electron beam powder bed fusion is particularly valued for its ability to produce intricate geometries that are often impossible to achieve with traditional manufacturing methods, making it a game changer in industries such as the aerospace, automotive, and medical ones.
The choice of metal alloys is critical in laser and electron beam powder bed fusion, as different materials exhibit varying properties, such as strength, ductility, and thermal conductivity. Commonly used alloys include titanium, aluminum, and stainless steel, each offering unique advantages for specific applications. Laser and electron beam powder bed fusion processes also allow for the customization of microstructures and mechanical properties through the careful control of processing parameters, such as laser/electron beam power, scan speed, and layer thickness.
Despite their advantages, challenges remain, including issues related to residual stress, porosity, and surface finish. Ongoing research aims to optimize laser and electron powder bed fusion techniques and broaden the range of usable materials, enhancing the technology's efficiency and applicability. Ultimately, laser and electron beam powder bed fusion represents a significant advancement in manufacturing, allowing for innovative designs and rapid prototyping in the production of metal components.

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. Materials is an international peer-reviewed open access semimonthly 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.
