Special Issue Information
Dear Colleagues,
The growth of automation since the beginning of the 21st century has prevailed in almost all production domains with the exception of large-scale applications (aerospace, construction, marine, etc.), in which the use of automatic tools is still challenging and at its first application stage.
Recent reviews of metal additive manufacturing processes distinguish them into three major categories: (i) powder bed fusion (PBF); (ii) directed energy deposition (DED); and (iii) sheet lamination.
In recent years, research effort has been intensively dedicated to the study of PBF material fabrication. The PBF process, although presenting small geometrical imperfections and mechanical characteristics in the order of traditional stainless-steel material, is limited by the build envelope of the equipment, which is typically a 250 mm cube. On the other hand, DED processes lie upon a more flexible building set-up, allowing for the realization of elements without theoretical dimensional constraints. For such reason, it appears more suitable for large-scale applications, for which the outputs requested are of the order of several meters (typically 3 to 5 m long). However, in order to obtain pieces of large dimensions, higher printing velocities are required, resulting in larger geometrical imperfections with respect to the digital model. Therefore, much effort is needed for a proper assessment of both the geometrical and mechanical characterization of the outputs.
To cover this topic and to provide a well-documented reference in this field, authors are invited to present their recent research results to this Special Issue. Suitable topics include, but are not limited to, the following:
- Material characterization of metal AM;
- Advanced design processes for metal AM;
- Applications of large-scale metal AM;
- Design requirements for large-scale metal AM 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. Applied Sciences 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 2400 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.
