Abstract :

Additive manufacturing (AM) opens a new era, including aircraft engine design and manufacturing. In addition to being capable of solving problems with complex shapes that are difficult to make with traditional methods, the revolutionary power of AM is due to the feature of making objects from micro to macro scale, similar to natural processes such as how living beings grow from small to large. Now one can put different materials together where needed, either mixed or embedded. One can proactively design micro structure under the surface of a structure to arrange distribution of mass, stiffness, damping, failure mode and its location, thermal property, etc., according to the functional requirement of the part. This is what we call Additive Design (AD), not design for AM. AD will be a new area of engineering that will change people's vision of design and lead to exploring the further capabilities of existing materials by optimizing the load distribution, such as reducing stress concentration substantially. We made a micro jet engine in 3 months using AD technology developed by a small group with young people of less than 10 members. From inlet to the tail nozzle, all parts are made of metal using SLM by outsourcing to different companies. The entire engine consists of no more than 15 parts. All parts have some features that are either difficult or impossible to be made by traditional methods. These features are characterized by light weight, structural integrity, and cost savings
