Design approach for metal additive manufacturing

Metal Additive Manufacturing (AM) technology allows the manufacture of parts and devices that are geometrically complex, have material elements and can be customized. To take advantage of these skills, it is important to assist designers in exploring untested regions of construction sites. Similarly the current paper provides the concept and method of using the Design for Additive Manufacturing (DFAM) method which includes conceptual design, process selection, latest design stages, and production design. This approach is based on the process-building-material-model behavior typical of building materials. Metal Powder Bed Fusion technology produces solid components, using a hot source to make the interaction between the powdered metal particles one layer at a time. Many Powder Bed Fusion technologies use powder-adding methods as the component is formed, resulting in the final component being added to the metal powder. The main difference in the steel technology Powder Bed Fusion stems from the use of different energy sources. An example CAD system is developed that integrates this approach. Examples of cellular design are used to illustrate the DFAM approach.
