Processes – R&D scenario analysis

,

An analysis of scientific papers published in the last 10 years (2008-2018) has been developed, selecting relevant papers through the Derwent Innovation tool. The tool permits to select papers within the Web of Science database.

Web of Science includes over 20,000 peer-reviewed, high-quality scholarly journals published worldwide (including Open Access journals); over 190,000 conference proceedings; and over 90,000 editorially selected books. It gives access to multiple databases that reference cross-disciplinary research, which allows for in-depth exploration of specialized sub-fields within an academic or scientific discipline.

A general search to define technological advances object of scientific research in the last decade was performed aiming at selecting efforts and results carried out in the field of processes for Additive Manufacturing and related technologies and  techniques.

Title/Abstract
(((additive adj manufacturing) or (3d adj print*)) and process* )

Starting from the general keywords related with Additive Manufacturing (AM) and 3D printing, coupled with the keyword addressing processing, the query was defined as reported in the table above, in line with the search performed for the selection of patents related to Processes for AM.

The query used additional filters to exclude results non-inherent to the scope of the present work.

The query selected a total of 712 scientific papers published between 2008 and 2018 related to Additive Manufacturing processes and related technologies. The papers published yearly are reported in the temporal trend of the figure below. 2018 is included, although results are still very partial.

The submission of scientific papers shows a positive trend in the temporal domain under analysis, with a strong growth in the last years.

Among the author’s affiliations, the organizations that emerged as the most active in the field of copper mining and extraction R&D are reported in the following graph.

The list is led by the United States Department of Energy (DOE), folowed by Centre National de la Recherche Scientifique, based in France. The following players are four Universities based in United States, namely Georgia University of Technology, University of Texas, Pennsylvania State University and State University of New York. The first European Organization active in the field of R&D of processes and related technologies for AM is the German research centre Fraunhofer-Gesellschaft. Other players appearing in the list of most active organizations are the Chinese Academy of Sciences, form China, the Indian Institute of technology, from India and the Nanyang Technological University of Singapore.

The analysis of the sources from which the selected articles were published permitted to select the most relevant Journals hosting publication on this technology field. The Journals emerged as the most recurrent are reported in the following graph.

The following map was draft utilizing the proprietary Themescape tool of the Derwent Innovation suite. Themescape performs a semantic analysis on the titles and abstract of papers and groups papers on the basis of top recurrent words. “Hills” represent a concentration of papers in correspondence of common keywords. Each point represents a papers of the dataset. Analysing the map is it possible to note some returning topics in correspondence of peaks.

The map permits to have a first overview of the main topics of R&D activity, providing a set of returning terms and technologies on which patent activity is focusing and giving indications on the development path of the sector.

In the following figure the map of recurrent topics automatically generated by the Themescape tool, on the basis of a semantic analysis of title and abstracts of papers is reported.
