Special Issue Information
Dear Colleagues,
Metallic additive manufacturing (AM) is gaining in popularity in the industry (aerospace, defense, nuclear, etc.) and in the medical sector, particularly the powder bed fusion (PBF) and the directed energy deposition (DED) categories of processes. In such critical sectors, the integrity and geometrical conformity to the numerical design of the manufactured parts need to be demonstrated.
First, to limit the defects and deviations from the numerical design, the implementation of digital twins of the AM process chain is a solution. Second, to limit the defects during the AM process, the monitoring of the process, coupled with a feedback loop, involving artificial intelligence (AI), is a solution. Third, to detect defects and deviations in the post-process AM parts, non-destructive testing (NDT) and metrology are required. However, the complexity in shape enabled by AM, including internal structures and the rough surface finish, poses a challenge to the quality control of AM parts. X-ray Computed Tomography (XCT), implementing cone beam or synchrotron radiation, is the most performing NDT method as it enables NDT and metrology. However, linear and nonlinear Resonant Ultrasound Spectroscopy (RUS), swept sine methods and Impulse Excitation Method (IEM), are alternative very performing methods for NDT. Moreover, considering dense and large DED parts, tomosynthesis and Phased Array Ultrasonic Testing (PAUT) are more adapted. In addition, the potential for inspection of these NDT methods can be increased by the implementation of IA, allowing the operator's influence to be limited.

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.
