This portfolio assignment presents an analysis of two journal articles focusing on the applications of 3D printing technology. The first article evaluates the use of 3D printing in designing lightweight unmanned aerial vehicle (UAV) wing structures, discussing design adaptability, fuel efficiency, and system agility. It highlights the use of compression testing and various structural designs like hexagonal diamond, 3D pyramidal, and 3D Kagome structures. The second article explores 3D printing in manufacturing and medicine, specifically ophthalmology, discussing its implications in creating engineering prototypes and medical applications like dental implants. The portfolio critiques both articles, suggesting improvements such as including real-time scenarios and addressing limitations to strengthen the research and its practical applications. The assignment is structured as a portfolio item requiring personal reflections and analysis of the provided research materials.
