New Materials and Concepts for Additive Manufacturing with Metals

Dear Colleagues,

As you all know, laser powder bed-based additive manufacturing techniques for processing metals are almost established techniques for producing highly complex components and parts. The almost unrestricted freedom of geometry, for example, enables the integration of cooling channels close to the contour to minimize local hot spots so that the processing time can be shortened and the component distortion of the semi-finished product can be minimized. In addition to the high design flexibility, components can be generated close to the contour due to the layer-by-layer material application, i.e., work- and energy-intensive post-machining is often not required.

Still, the limited material spectrum and low process speeds have so far impeded the breakthrough of additively manufactured components on a large scale. For this reason, new materials are increasingly being developed explicitly for the AM process employing computer-based materials design.

The present Special Issue on “New Materials and Concepts for Additive Manufacturing with Metals” may become a status report summarizing the progress achieved in the last five years, as well as recent research.

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.
