Feature papers represent the most advanced research with significant potential for high impact in the field. A Feature
Paper should be a substantial original Article that involves several techniques or approaches, provides an outlook for
future research directions and describes possible research applications.
Feature papers are submitted upon individual invitation or recommendation by the scientific editors and must receive
positive feedback from the reviewers.
Editor’s Choice articles are based on recommendations by the scientific editors of MDPI journals from around the world.
Editors select a small number of articles recently published in the journal that they believe will be particularly
interesting to readers, or important in the respective research area. The aim is to provide a snapshot of some of the
most exciting work published in the various research areas of the journal.
On 25 July 2023, MDPI and the journal Quantum Beam Science (QuBS, ISSN: 2412-382X) organized the webinar Laser-Based Manufacturing Techniques.
Additive manufacturing (AM) methods have grown and evolved rapidly in recent years. Current methods for AM have been categorized into seven main groups, which are material extrusion, material jetting, vat polymerization, powder bed fusion, directed energy deposition, sheet lamination and binder jetting. In these techniques, beam technologies such as lasers and ultrasound play integral roles during the processes, which have resulting effects on the 3D printed parts.
In this webinar, we have three speakers covering topics from the development of metal 3D printing systems, using laser direct writing to fabricate biomimetic structures to the use of ultrasonic imaging for non-destructive testing for multi-material parts produced by additive manufacturing. Dr. Joonphil Choi gave an overview on the development of 3D printing in the Korea Institute of Machinery and Materials, Dr. Wenhui Yu followed up with her presentation on laser direct writing for surface modifications and, finally, Dr. Rao Jing presented her work on using non-destructive testing for 3D printed parts.
