Additive Manufacturing also known as 3D Printing is a process whereby a real object of virtually any shape can be created layer by layer from a Computer Aided Design (CAD) model. As opposed to the conventional Subtractive Manufacturing that uses cutting, drilling, milling, welding etc., 3D printing is a free-form fabrication process and does not require any of these processes. The 3D printed parts are lighter, require short lead times, less material and reduce environmental footprint of the manufacturing process; and is thus beneficial to the aerospace industry that pursues improvement in aircraft efficiency, fuel saving and reduction in air pollution. Additionally, 3D printing technology allows for creating geometries that would be impossible to make using moulds and the Subtractive Manufacturing of drilling/milling. 3D printing technology also has the potential to re-localize manufacturing as it allows for the production of products at the particular location, as and when required; and eliminates the need for shipping and warehousing of final products.

3D printing conquers new branches of production due to becoming a more reliable and professional method of manufacturing. The benefits of additive manufacturing such as part optimization, weight reduction, and ease of prototyping were factors accelerating the popularity of 3D printing. Additive manufacturing has found its niches, inter alia, in automotive, aerospace and dentistry. Although further research in those branches is still required, in some specific applications, additive manufacturing (AM) can be beneficial. It has been proven that additively manufactured parts have the potential to out perform the conventionally manufactured parts due to their mechanical properties; however, they must be designed for specific 3D printing technology, taking into account its limitations. The maritime industry has a long-standing tradition and is based on old, reliable techniques; therefore it implements new solutions very carefully. Besides, shipbuilding has to face very high classification requirements that force the use of technologies that guarantee repeatability and high quality. This paper provides information about current R&D works in the field of implementing AM in shipbuilding, possible benefits, opportunities and threats of implementation.

This is a review paper on 3D printing, its significance, and future scope in the aircraft industry.In this article, additive manufacturing is compared with traditional manufacturing in the context of the aircraft industry that gives more accurate knowledge about how additive manufacturing is more effective in terms of cost-cutting, waste prevention, customization, and large-scale production. We will go into the need for 3D printing technology, how it has taken in step over other manufacturing process and are being used for a host of different applications. The paper gives sufficient information about various types of material used in additive manufacturing with the applications, examples, requirements, and process moreover some overview of limitations as well. How Rapid tooling is used with a different process to reduce time and get more productive and efficient parts for the aircraft industries. The use of 3D printing technology in the aircraft industry plays a major role and gained immense applications. It has greatly affected the production line due to its flexibility and ease of production. It is capable of producing intricate parts, a more resilient and lightweight structure that achievesa weight reduction of 40-60%, subsequently result in a leaner cost structure, material saving, and lower fuel consumption.The last section deals with the future scope of additive manufacturing in the aircraft industry with various parameters design aircraft wings, complex design parts, additive manufacturing in space. More companies and the aerospace industry continue to see the value of 3D printing and begin developing on-site 3D printing operations and investing in the technology

Three-dimensional or 3D printing technology is a growing interest in medical fields like tissue engineering, dental, drug delivery, prosthetics, and implants. It is also known as the additive manufacturing (AM) process because the objects are done by extruding or depositing the material layer by layer, and the material may be like biomaterials, plastics, living cells, or powder ceramics. Specially in the medical field, this new technology has importance rewards in contrast with conventional technologies, such as the capability to fabricate patient-explicit difficult components, desire scaffolds for tissue engineering, and proper material consumption. In this chapter, different types of additive manufacturing (AM) techniques are described that are applied in the medical field, especially in community health and precision medicine.

With the advancement of full scale 3d printing technology, industrialized building construction is rapidly moving towards a highly process-idiosyncratic and expressionist architecture of material sausages. Drawing connections between local vernacular (ancient modern) earth construction techniques and automated additive manufacturing strategies, this paper explores the potential for 3d printed architecture across the Americas, dissecting the technology’s ecological advantages and architectural possibilities in the process.
