Special Issue Information

Dear Colleagues,

Additive manufacturing (AM), being one of the most common technological methods worldwide nowadays, is a modern promising approach, for which scientific and technological boundaries are still not understood clearly due to the extremely fast development that has occurred in recent years. AM is highly attractive to scientists, as well as to mechanical, materials, chemical, and biomedical engineers and technologists, and it involves not only different important issues of physics and chemistry, but also machinery, software, machine learning, process organization, control, optimization and repeatability, economics, materials characterization, failure analysis and quality assurance, etc. The main reason for its popularity is the unique possibility of combining AM with different 3D printing technologies relevant to a wide spectrum of materials (metals, ceramics, composites, polymers, organics, etc.) with processes digitalization and artificial intelligence.

This Special Issue provides a forum for researchers, engineers, and practitioners to report their latest achievements and to highlight critical issues and challenges for future investigations of the design and applications of 3D printing and additive manufacturing.

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.

The hole-drilling method (HDM) is a common technique used for the determination of residual stresses, especially for metal alloy components, though also for polymers. This technique is usually implemented with strain gages, though other methods for determining the fields of displacements are quite mature, such as the use of digital image correlation (DIC). In the present paper, this combined methodology is applied to a 3D-printed PLA precurved specimen that is flattened in order to impose a bending distribution which can be considered known with a reasonable accuracy. The back-calculated stress distribution is in agreement with the expected (imposed) bending stress, however, a converging iterative procedure for obtaining the solution is introduced and discussed in the paper.
