Structure Design and Microstructure Control for Metal Additive Manufacturing

Dear Colleagues,

Additive manufacturing (AM), also known as 3D printing, encompasses a series of technologies that allow components to be fabricated layer by layer. Due to its ability to produce components with high resolutions, complex geometries, and high mechanical performances, AM technologies have rapidly developed over the past decade. AM can be used for the fabrication of metals, ceramics, and polymers. Metal AM technologies mainly include direct energy deposition (DED) and powder bed fusion (PBF). In addition, a few alternative methods such as binder jetting are also recognized as metal AM by the American Society for Testing and Materials (ASTM International). Metal AM technologies have been employed in many fields, such as aerospace, biomedicine, and automobiles. As effective tools allowing for a high degree of product freedom, the structure design for metal AM technologies can be quite different. New designs allowing for remarkable performance enhancements can be explored. Moreover, the mechanical properties of the lightweight structure depend on the bulk materials. The properties of dense parts are strongly correlated with the microstructure. Here, studies related to microstructure control are also attractive. Accordingly, this Special Issue seeks to showcase research papers, short communications, and review articles that focus on (1) novel structure design for metal AM and (2) microstructure control for metal AM via processing and post-processing.

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. Micromachines 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.
