Special Issue Information

Dear Colleagues,

Compared to traditional manufacturing methods, additive manufacturing (AM) allows the production of complex parts with a shorter lead time. This process offers a cost-efficient alternative to conventional methods. Laser-based AM is a rebellious technique for fabricating a broad spectrum of materials, predominantly metallic materials used in end-use applications under industrial environments. 

However, the industry's requirements for manufacturing technology are continuously unwinding and becoming increasingly complex and uncompromising. Indeed, further research must be conducted to understand process physics better, optimise processes, and develop novel applications. Thus, this Special Issue strives to offer a forum for valuing state-of-the-art advances, encouraging and enabling the new development and applications of laser-based additive manufacturing of advanced metallic materials, including the characterisation and evaluation. Both original and review research papers are welcomed by scientists, researchers, engineers and all experts in this field. Topics include but are not limited to the following areas:

  • Laser powder bed fusion AM;
  • The laser-based direct energy deposition technique;
  • Laser-based hybrid AM;
  • Modelling and simulation of laser-based 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. Metals 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 2600 CHF (Swiss Francs).

The discovery of the utility of various titanium alloys as implant biomaterials has resulted in these materials becoming far more popular than other metals in the medical world. However, the production of these materials using additive manufacturing has its own challenges some of those being the surface finish that can be used as an implantology material. As such, the purpose of this study is to evaluate the influence of 3D-printed Ti64ELI on the as-built samples printed at 60°, 90°, and 180° orientations. Such studies are very limited, specifically in the development of the laser shock peening surface modification of dental implants. The study showed that each mechanical test that was performed contributes differently to the printing orientation, e.g., some tests yielded better properties when 180° printing orientation was used, and others had poorer properties when a 180° printing orientation was used. It was observed that 60° testing yielded a micro-hardness value of 349.6, and this value was increased by 0.37% when 90° orientation was measured. The lowest HV value was observed under a 180° orientation with 342.2 HV. The core material volume (Vmc) was 0.05266 mm3/mm2 at a 60° orientation, which increased by 11.48% for the 90° orientation. Furthermore, it was observed that the surface roughness (Sa) at 60° orientation was 43.68 μm. This was further increased by 6% when using the 90° orientation. Full article
