Additive Manufacturing (AM), as defined by ASTM International Committee F42, is the process of joining materials to make objects from three-dimensional (3D) model data, usually layer by layer, as opposed to subtractive manufacturing methodologies. Traditional manufacturing processes are subtractive, creating the object by machining, forming, casting, etc. AM converts computer-aided design (CAD) models to Standard Tessellation Language (STL), the de facto standard. The STL file describes the external closed surfaces of the original CAD model and forms the basis for calculation of the slices. Thus, it can be used to construct the 3D objects layer by layer using various materials (e.g. metallic, plastic).

In this course, engineering materials and their properties are first reviewed. Traditional manufacturing such as casting, forming, machining, and joining processes are introduced and discussed. Additive manufacturing is then presented. Both general process chain and specific processes are presented (e.g. photopolymerization, powder bed fusion process). Materials properties of each manufacturing process are examined and compared to each other. Design and optimization for AM is highlighted. Real engineering applications are reviewed and discussed. A final project is required so that student can gain experiences in the entire AM process.
