The concept of additive manufacturing is put forward on the basis of the nowadays research hotspot-3D print. This paper focuses on the main branch technology of additive manufacturing, i.e., electron beam melting (EBM) in high energy beam rapid manufacturing area, enumerating the advantages of EBM compared with laser rapid prototyping and introducing its process principle as well as its research status. The application situation of EBM in aerospace especially it’s utility in aircraft engine and industrialization of industrial aspects was also introduced, and its development prospect in the future was forecasted.

The industrial expectation and future of the additive process, also DLM (Digital Layer Manufacturing) called, is the extensive use in Rapid Manufacturing (RM). These manufacturing technologies are at this point in time emerging. The tool-less economical manufacture of short runs plastic components is real life in several branches. These technologies emerge from the Rapid Prototyping and are on the way to Rapid Manufacturing, demonstrating great future chances. At the same time it puts forward several great research and development challenges. The paper, starting with background information, shows trends toward RM. Case studies from own research and experience as well as pioneer projects demonstrating the transition toward RM. The present challenges are discussed and considered alongside the technical and economical perspectives. Chances like “complexity for free”, individualization of design, mass customization and others are demonstrated, some final conclusions are stated.

The Cost

The development and manufacturing speed of products have become the focus of competition, at the same time the manufacturing not only has to meet user’s constantly changing needs, but also has to have a relatively strong flexibility of manufacturing technologies. Additive processes can be defined as rapid prototyping, which generate parts (prototyping) in a layered way, is gaining progress by rapid tools (RT) and rapid manufacturing (RM) for production of functional parts in small quantity and even one product without adding the cost becomes more and more critical. The paper describes which mechanism of stereo lithography (SLA) rapid prototyping can be applied to rapid tooling for production complex geometries for long-term consistency. Moreover, the paper demonstrates the application examples of rapid tooling fulfilling the required physical, mechanical and geometrical properties in precision deformation and casting process. The most notable advantage is the integration of production design and digital manufacturing within the product development period.

Design Freedom

AbstractAdditive Manufacturing technologies are based on a layer-by-layer build-up. This offers the possibility to design complex geometries or to integrate functionalities in the part. Nevertheless, limitations given by the manufacturing process apply to the geometric design freedom. These limitations are often unknown due to a lack of knowledge of the cause-effect relationships of the process. Currently, this leads to many iterations until the final part fulfils its functionality. Particularly for small batch sizes, producing the part at the first attempt is very important. In this study, a structured approach to reduce the design iterations is presented. Therefore, the cause-effect relationships are systematically established and analysed in detail. Based on this knowledge, design guidelines can be derived. These guidelines consider process limitations and help to reduce the iterations for the final part production. In order to illustrate the approach, the spare parts production via laser powder bed fusion is used as an example.
