Available in PDF, EPUB and Kindle. Book excerpt: The present Thesis "Qualification of SLM - Additive Manufacturing for Aluminium Alloys" considers the suitability of two aluminum alloys for the additive manufacturing technique Selective Laserbeam Melting (SLM). High cooling rates can be realised in SLM which allow the use of the tailored Al-alloy options Scalmalloy and SilmagAl. The investigations deepen the scholarly understanding of processing both alloys in SLM. Different aspects of the process chain are described, analysed and discussed with regard to define powder and material specifications for aerospace applications. Main process influencing powder characteristics are identified and characterising techniques are discussed. The additive manufactured material of both alloys is comprehensively investigated regarding mechanical and physical properties. As result, different processing routes are identified which aim to meet the final proposed material specification for principle structural elements (PSE) and non-principle structural elements (non-PSE) in aerospace qualifications.

Book Synopsis Analysis of the Optimal Parameters for 3D Printing Aluminum Parts with a SLM 280 Machine by : Víctor Algara Muñoz
Download or read book Analysis of the Optimal Parameters for 3D Printing Aluminum Parts with a SLM 280 Machine written by Víctor Algara Muñoz and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive Manufacturing (AM) is an alternative manufacturing process, which has gained popularity and interest over the manufacturing industry for its benefits. Among the different AM processes, Selective Laser Melting (SLM) is one of the most promising ones since it enables the production of complex metallic parts from loose powder. Parts are produced adding material layer by layer with a high-powered laser that melts the powder bed. Thanks to this, optimal designs and light-weight components can be manufactured. Aluminum alloys have exceptional strength and stiffness in relation with its density, when compared with other materials. That is the main reason why it is a perfect candidate for this type of process, and nowadays it is extensively used for aerospace and automotive industry. Although these several advantages that SLM provides, parts manufactured with this process usually present porosity. Porosity is caused when non-appropriate parameters are used within the buildup process. Elevated levels of porosity lead to a decrease on the relative density value of the SLM pieces, being the cause of poor mechanical properties or even the fracture of it. The ability of producing complex parts is not enough, it must be complemented with high performance and high mechanical properties. Therefore, the relative density of SLM parts must be studied and enhanced to the highest possible value. In this project, relative density of AlSi10Mg samples produced with a SLM 280 will be studied. Relative density will be measured by changing the main process parameters used within the buildup process. The goal is to have a better understanding of the behavior of the relative density against those variations, and to find those parameters that achieve the highest value. With the best parameters obtained, tensile specimens will be produced and pulled to get values of the mechanical properties. This research should also serve as a guideline for future investigation of the same nature. The part performance is highly influenced by external uncontrollable factors such as the machine used, the powder and the environment of the chamber. That is the reason why it is so important to have a defined guideline with all the steps to be followed. Another reason to have a welldefined guideline is the fact that new materials are continuously being added to the SLM process. Therefore, even though the material properties are different, the process to achieve high relative density values should be similar.

Download or read book Additive Manufacturing Volume 2 written by Prashanth Konda Gokuldoss and published by MDPI. This book was released on 2020-04-15 with total page 351 pages. Available in PDF, EPUB and Kindle. Book excerpt: Additive manufacturing (AM) is one of the manufacturing processes that warrants the attention of industrialists, researchers and scientists, because of its ability to produce materials with a complex shape without theoretical restrictions and with added functionalities. There are several advantages to employing additive manufacturing as the primary additive manufacturing process. However, there exist several challenges that need to be addressed systematically. A couple such issues are alloy design and process development. Traditionally alloys designed for conventional cast/powder metallurgical processes were fabricated using advanced AM processes. This is the wrong approach considering that the alloys should be coined based on the process characteristics and meta-stable nature of the process. Hence, we must focus on alloy design and development for AM that suits the AM processes. The AM processes, however, improve almost every day, either in terms of processing capabilities or processing conditions. Hence, the processing part warrants a section that is devoted to these advancements and innovations. Accordingly, the present Special Issue (book) focuses on two aspects of alloy development and process innovations. Here, 45 articles are presented covering different AM processes including selective laser melting, electron beam melting, laser cladding, direct metal laser sintering, ultrasonic consolidation, wire arc additive manufacturing, and hybrid manufacturing. I believe that this Special Issue bears is vital to the field of AM and will be a valuable addition.

Book Synopsis Mechanical Engineering by : Sasan Dadbakhsh
Download or read book Mechanical Engineering written by Sasan Dadbakhsh and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Selective laser melting (SLM) is an additive manufacturing technique to produce complex three-dimensional parts through solidifying successive layers of powder materials on top of each other, from the bottom to top. The powder base nature allows the SLM to process a wide variety of materials and their mixtures and fabricate advanced and complicated composite parts. However, the SLM is a newly established process and seeks detailed scientific studies to develop new materials systems for the consumption of industry. These scientific studies are particularly important because of many issues associated with the SLM process, such as porosity, balling, delamination, thermal stress, etc, which can be varied from one material system to another. This PhD project aims to elucidate the fundamental mechanisms governing the microstructure and mechanical properties of the metallic and in-situ AI matrix composite parts made by SLM. The research starts with a preliminary study on SLM of stainless steel in order to explore the usage of SLM machine and related parameters. It illustrates the effect of part layout on the quality of products. The main research focuses on the in-situ formation ofparticulate reinforced AI matrix by using SLM of AIIFe203 powder mixture. It is a pioneering research to integrate in-situ interaction with laser melting to produce advanced AI composites. It investigates the mechanisms governing SLM assisted in-situ reaction and also the effects of various parameters such as SLM layer thickness, laser power and scanning speed as well as·the proportion ofFe203. It examines the influence of AI alloy powder and it describes the effect ofhot isostatic pressing (HIP) post-treatment. The physical, mechanical, and metallurgical properties of the products are extensively assessed using various techniques. The processing windows of the process are sketched. The findings demonstrate unique microstructural features due to combined in-situ reaction and laser rapid consolidation, and contribute to provision of an in-depth scientific understanding of novel AI matrix composites by using SLM assisted in-situ processes. As part of this PhD project, industrial collaborative research has also been conducted to characterise the surface finish, metallurgical quality, process accuracy and mechanical properties of various SLM made metallic parts using AI, Ti, stainless steel, and super alloys. This part of research has generated scientific data and results for industrial applications ofmetallic fabrication using SLM.

Book Synopsis A V-Model Framework to Support Qualification of Metal Additive Manufacturing Parts Made with Laser Powder Bed Fusion by : Byeong Min Roh
Download or read book A V-Model Framework to Support Qualification of Metal Additive Manufacturing Parts Made with Laser Powder Bed Fusion written by Byeong Min Roh and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation presents a novel framework for monitoring metal additive manufacturing (AM) processes for quality assurance using process signatures occurring during the laser powder bed fusion process. The framework offers a structured approach based on the Systems Engineering V-model to translate part requirements into process signatures that can be monitored using in situ sensing technologies. A method for selecting sensors based on the process signatures of interest is also developed to address a related shortcoming in the field. Information gathered from the selected sensors during the build is used to ascertain build quality with respect to the microstructure and mechanical properties of the resulting metal AM part. This information can then be used for quality assurance, validating that the requirements are met by the metal AM part. The V-model framework and sensor selection method for laser powder bed fusion are demonstrated and tested using existing Ti-6Al-4V and IN625 test data from the literature to validate traceability and requirements for density and ultimate tensile strength. The contributions of the work are discussed in this dissertation, along with limitations and future work.
