Abstract

The growing need for ever-changing customer demand pressurizes the manufacturing industry to look for a flexible and fast-changing small-volume production system. As a result, additive manufacturing (AM) is one of the fastest-growing methods of changing a 3D design model to a 3D product without any process planning method. A major aspect of 3D printing technology is its ability to produce parts which are not possible by traditional manufacturing techniques. The students at any level can be introduced to the technology and understand the theoretical aspects in coordination with practice in the laboratory. The paper examines the underlying 'rules' that help companies take full advantage of additive manufacturing technologies.

The paper also examines the guidelines for design of additive manufacturing with in-depth discussion of design constraints. These guidelines are discussed in view of creating light weight parts, efficient heat exchangers and components for aerospace industries. The paper investigates different influencing variables including the variation due to density and porosity. Other modeling equations that influence the additive process are examined, which include energy balance equations for melting and vaporization. Post processing of 3D additive components is also critical to the outcome of overall process as it impacts resulting surface quality, total cycle time and cost.
