Basics of Fused Deposition Modelling (FDM)
TL;DR: An overview of the basic principles of fused deposition modeling, commonly known as 3D printing technology, is presented in this article, where applications of FDM in various fields are also highlighted with a focus on an interesting role the 3D printer technology is playing in the fight against Covid-19 pandemic.
Journal ArticleDOI
Properties of physically deposited thin aluminium film coatings: A review
TL;DR: In this paper, the properties of thin aluminium films and their complex interactions with process parameters are discussed and the significance of optimising the deposition methods and identifies research gaps in the published studies is highlighted.
Journal ArticleDOI

Reza Shakoury,Sahar Rezaee,Fredrick Madaraka Mwema,Fredrick Madaraka Mwema,Carlos Luna,Koushik Ghosh,Stanislav Jurečka,Ştefan Ţălu,Ali Arman,Alireza Grayeli Korpi +9 more
TL;DR: In this paper, the micromorphology of tantalum pentoxide (Ta2O5) thin films, deposited on glass substrates by electron gun method, has been analyzed using atomic force microscopy (AFM), UV-Vis-NIR spectrophotometry and multifractal analyses.
Journal ArticleDOI
Atomic force microscopy analysis of surface topography of pure thin aluminum films
Fredrick Madaraka Mwema,Oluseyi Philip Oladijo,Oluseyi Philip Oladijo,T.S. Sathiaraj,Esther T. Akinlabi +4 more
TL;DR: In this paper, the surface structure evolution, roughness and distribution of thin aluminium thin films were examined and discussed using atomic force microscopy, and the results showed that the morphologies of the surface structures of Al thin films vary with power and substrate type.
Book ChapterDOI
