“…It was noted that the ultimate compressive strength and the ultimate compressive strain were inferior to conventional Al7075. It is seen that there is certain amount of decrease in MgZn 2 and Mg 2 Si (The presence of Si, Mg can also form Mg 2 Si, a hardening phase observed for casting aluminium alloys) phase. X-Ray Fluorescence results show that there is decrease in percentage in Zn and Mg. Table 2 shows this property of SLM manufactured component [8].…”

Abstract-Additive Manufacturing (AM) process has been effective in producing materials that are being utilized by the aerospace industry in order to improve their performance by increasing their properties. Industry now opts for this technique over conventional methods as it has enormous advantages and applications. This Additive Manufacturing process is capable of producing complex near net shape of parts. The materials that are produced by this technique for aerospace industries are metal alloys, metal matrix composites, polymer matrix composites, ceramic matrix composites and nano-composites. Many of the composite materials are still under research and development. In this study, a literature review on the mechanical properties of the materials that are used in the aerospace industry by AM process is discussed and these properties are also compared with the materials produced by conventional methods. The purpose of this review is to highlight the importance of Additive Manufacturing technique and also understand the effect of this process on the materials tested. During this work, the evolution of materials in the aerospace sector, the basic concept of AM technique, the application of the materials, the properties obtained when processing is done, the limitations and the scope for research are given.

Access to cadaveric specimens, which is dependent on donation and heavy equipment, is still a limiting factor in the study of anatomy. As there are many spatially challenging structures throughout the human body for which physical support is beneficial, new strategies are always needed to implement new interactive teaching techniques to help students more efficiently grasp the complex organization of the human body. In this report, the author reveals the use of rapid prototyping technology to create an innovative and anatomically accurate teaching tool to engage students and help them build threedimensional (3D) mental maps of the human heart. The model consists of polylactic acid (PLA) thermoplastic deposited layer by layer on a platform in a pattern that corresponds to a digital Standard Tessellation Language (.stl) file. Printing a hollow human heart with a 1:1 ratio was rapid (<5 hrs) and affordable (approximatively US$5 per model). Given access to the appropriate printable digital files, students could print their own model and could subsequently paint them appropriately to give them an anatomically correct representation. This studentcentered activity is an extension of the current anatomy coloring textbooks, with the benefit of building an accurate 3D representation of the human body.

“…Examples of other commercialized AM processes are laser sintering, laser melting, fusion deposition modeling, multi-jet modeling, electron beam melting, laminated object manufacturing, plaster-based 3D printing, laser engineered net shaping, shaped metal deposition, and powder bed-inkjet head 3D printing [5]. There are a lot of capabilities for AM implementation and adoption in industry; some of these are [6]:…”

-As a first step of applying additive manufacturing (AM) technology, plastic prototypes have been produced using various AM Process such as Fusion Deposition Modeling (FDM), Stereolithography (SLA) and other processes. After more research and development, AM has become capable of producing complex net shaped in materials which can be used in applicable parts. These materials include metals, ceramics, and composites. Polymers and metals are considered as commercially available materials for AM processes; however, ceramics and composites are still considered under research and development. In this study, a literature review on design for AM of composite materials and potential alloys is discussed. It is investigated that polymer matrix, ceramic matrix, metal matrix, and fiber reinforced are most common composites through AM. Furthermore, Functionally Graded Materials (FGM) is considered as an effective application of AM because AM offers the ability to control the composition and optimize the properties of the built part. An example of FGM through using AM technology is the missile nose cone which includes an ultra-high temperature ceramic graded to a refractory metal from outside to inside and it used for sustaining extreme external temperatures. During this work, different applications of AM on different classifications of composite materials are shown through studying of industrial objective, the importance of application, processing, results and future challenges.
