OVERVIEW OF ADDITIVE MANUFACTURING AND QUALITY ASSURANCE OF POWDERS FOR SPACE PROPULSIVE COMPONENTS

Additive manufacturing techniques are modifying the space propulsion manufacturing panorama. These technologies, which are already implemented in manufacturing of aerospace components, are still to be further analyzed and a complete quality assurance program to be defined. In this article, a state of the art analysis of quality assurance for space propulsive applications is described. In particular, the focus is centered on material challenges associated to space propulsion: the research is oriented towards metal powders and samples implemented in selective laser melting/powder bed fusion technologies. In particular, a qualification process of the supply chain related to metal powders in space propulsion is reported. Furthermore, the application of this process to a case study material is detailed, and preliminary result data are considered. Finally, a review of the qualification process is performed and suggestions for future work on this topic are presented.

Additive Technologies and Their Applications in Furniture Design and Manufacturing

This paper deals with an overview of additive manufacturing and its segment - 3D printing, which is today rapidly and widely used (Agashe et al., 2020) for personal and high-capacity production. The paper discusses the possible positive factors such as small and personalized production series, cheaper design and production process, complex geometry, bionic structures (whose surfaces are complicated to make, and are copy of biological organisms) and negative factors such as lack of educated specialists and trainings. Those facts are affecting the implementation of these technologies in different segments of the design, product development and furniture production. The impacts of new technologies on the design and production of rapid prototypes and finished products in furniture industry are analyzed. The positive results of using additive manufacturing indicate that, in spite of minor obstacles and problems with connecting different production processes, additive production will have a significant place in the future of furniture design and production. The most important advantages of 3D printing is fast prototyping, one piece production, free form designing and the use of bio-based materials and their possibility of recycling.

Influence of Process Parameters on the Characteristics of Additively Manufactured Parts Made from Advanced Biopolymers.

Over the past few decades, additive manufacturing (AM) has become a reliable tool for prototyping and low-volume production. In recent years, the market share of such products has increased rapidly as these manufacturing concepts allow for greater part complexity compared to conventional manufacturing technologies. Furthermore, as recyclability and biocompatibility have become more important in material selection, biopolymers have also become widely used in AM. This article provides an overview of AM with advanced biopolymers in fields from medicine to food packaging. Various AM technologies are presented, focusing on the biopolymers used, selected part fabrication strategies, and influential parameters of the technologies presented. It should be emphasized that inkjet bioprinting, stereolithography, selective laser sintering, fused deposition modeling, extrusion-based bioprinting, and scaffold-free printing are the most commonly used AM technologies for the production of parts from advanced biopolymers. Achievable part complexity will be discussed with emphasis on manufacturable features, layer thickness, production accuracy, materials applied, and part strength in correlation with key AM technologies and their parameters crucial for producing representative examples, anatomical models, specialized medical instruments, medical implants, time-dependent prosthetic features, etc. Future trends of advanced biopolymers focused on establishing target-time-dependent part properties through 4D additive manufacturing are also discussed.

Significant potential and materials used in additive manufacturing technologies towards sustainability

Additive Manufacturing (AM) has tremendous applications in this decade, which speeding up various design, engineering, and manufacturing processes. AM encompasses 3D Printing, 3D Scanning, and software support for designing, printing, and post-processing. It is helpful to the specific stages of the product development cycle by allowing manufacturers to produce better sustainable products than those previously limited by the limitations of traditional production techniques. This technological platform enables engineers and scientists to develop more robust and lighter functional geometries. It triggers an innovative surge in design. AM allows firms to produce complicated components that could not be produced through conventional technologies. 3D printers speed up tool cycles, improve measures and tests, and deliver customised solutions in every element of the development process. 3D printing lays the material in several layers until the product is manufactured per the requirements. This study provides a quick overview of AM, its substantial benefits, and the various types of AM that have been researched. Materials from the three polymers, ceramics, and metals classes have been utilised in all AM processes. This study also discussed the latest developments, featured AM-based process classes, and identified materials used in AM technologies. The authors have identified and discussed seventeen significant potentials of AM and finally discussed AM's potential for Sustainability. 3D printing offers incredible design flexibility, enabling us to build passageways that enhance performance, giving customers and operations great value. The benefits of AM for sustainability are evident in the manufacturing environment today. Readers should be able to access the knowledge structure of the subject through this study, which will assist them in recognising past research, the most active research clusters, and the strength of research relationships.

A state-of-the-art review on energy consumption and quality characteristics in metal additive manufacturing processes

This paper aims to study the energy consumption and quality characteristics of the parts fabricated by additive manufacturing (AM) technologies with a special focus on metal AM processes. AM is a family of manufacturing techniques, which is broadly used to fabricate complex and lightweight structures. The energy savings during AM processes have a significant influence on the AM industry, only if the quality of the fabricated part meets the requirements. The quality is generally represented by the surface and dimensional quality, mechanical properties, relative density, hardness, etc. The energy saving is important for environmentally benign and cleaner production, and improved product quality is useful for its application as a functional part in the aerospace, automobile, and biomedical industries. A comprehensive review of the energy consumption and quality characteristics of AM-fabricated (with special focus on metal AM) parts was carried out. Firstly, the specific energy consumption of various AM techniques has been reviewed to address the importance of energy and cleaner production. Then, the qualifications of products fabricated by different metal AM techniques have been discussed for different materials, such as titanium alloys, steel alloys, nickel alloys, and aluminum alloys. Also, by considering the practical importance of thin-walled structures fabricated by AM, a detailed analysis of their qualification has been presented. Moreover, different optimization techniques have also been reviewed for various AM process parameters and objectives. Overall, this paper provides an overview of AM, including a survey on the energy consumption and quality characteristics with the development of AM technologies for manufacturing of quality products. Finally, several future research directions are suggested, specifically the need for a framework for metal AM processes for the fabrication of quality products with minimum energy consumption.

Toward Additively Manufactured Electrical Machines: Opportunities and Challenges

With the growing interest in electrification and as hybrid and pure electric powertrains are adopted in more applications, electrical machine design is facing challenges in terms of meeting very demanding performance metrics, for example, high specific power, and harsh environments. This provides clear motivation to explore the impact of advanced materials and manufacturing on the performance of electrical machines. This article provides an overview of additive manufacturing (AM) approaches that can be used for constructing electrical machines, with a specific focus on additively manufactured iron core, winding, insulation, and permanent magnet, as well as cooling systems. Since there has only been a few attempts so far to explore AM in electrical machines (especially when it comes to fully additively manufactured machines), the benefits and challenges of AM have not been comprehensively understood. In this regard, this article offers a detailed comparison of multiple multimaterial AM methods, showing not only the possibility of fully additively manufactured electrical machines but also the potential significant improvements in their mechanical, electromagnetic, and thermal properties. The articles will provide a comprehensive discussion of opportunities and challenges of AM in the context of electrical machines.
