Special Issue Information

Dear Colleagues,

AM laser and EB powder bed fusion are today well-known research, development, and production technologies for generating complex, high-quality components and structures. The macrostructures of LPBF- or EBPBF-prepared components appear as collages of solidified track segments, which have been re-melted several times by the adjacent beam traces during the AM process. The high cooling rate of a small weld pool that characterizes these processes leads to the formation of very fine microstructures and improved mechanical properties. The parts can be found in products from the automotive, aerospace, and optical industries, as well as in the medical and telecommunications industries. Normally, for industrial purposes, a higher process output is desirable; other important factors are staff safety, product end-quality, and robust manufacturing.

In this Special Issue of JMMP, the submissions should be related to materials processing and/or manufacturing. It is worth noting that numerical simulation should be validated by experimental results and include the pertinent data. We are looking for recent innovations that focus on:

  • improved and/or new feedstock powder
  • multi-material manufacturing
  • process monitoring for sound/robust manufacturing
  • process stability improvement
  • enhancing product quality and dimensional accuracy
  • decreasing manufacturing lead time
  • increasing production rate

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. Journal of Manufacturing and Materials Processing 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 1800 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.

Additive manufacturing is a novel and breakthrough technology by which parts can be manufactured for various purposes and services. As in any production process, the desired properties of additively manufactured components, particularly in electron beam melting processes, ultimately depend on the manufacturing process parameters. Process parameters should be designed accordingly to manufacture parts with specific and desired characteristics. This study focuses on examining the effect of process parameters, such as beam current and velocity, focus offset, and line offset, at three different values each, on the properties of Ti-6Al-4V alloy. The study on the effect of the process parameters on the as-built material’s performance was performed using the Taguchi approach using an L9 (34) orthogonal array. The properties of printed parts (density, surface roughness, elastic moduli, hardness, tensile characteristics, fractography, and microstructure) were tested. A wide range of properties was obtained and analyzed; namely, porosity varied from 8% to almost fully dense materials with density higher than 99.9% and a range of yield and ultimate tensile strength values and brittle samples with less than 1% elongation to ductile samples with an elongation greater than 16%. The overall performance of printed parts was determined based on an evaluation criterion. Several parameter combinations were found and yielded the fabrication of parts with high density and relatively fine microstructure. The comparison of the best parameter combinations determined in this study and the parameters recommended by the machine manufacturer showed that improved results were obtained, and even when using the optimal parameters, they can be improved even more. This result highlights the ability of the proposed DOE method to further develop existing results and even for development of manufacturing parameters for new materials. Full article
