Selective laser melting of multi material
description With the increased demand for customised products with unique geometries and features, current manufacturing methods are challenged to produce complex shapes. Additive manufacturing is gradually replacing the traditional manufacturing methods to come up with complex parts required in small quantities. Additive manufacturing for multi materials in polymers has been researched more comprehensively compared to multi materials for metals. This is due to the lower working requirement for the polymers and plastics. However, metallic multi materials possess huge potential for application in our lives. One example would be making use of the strength of stainless steel for the outer support structure and the high heat conductivity of copper inside to control the direction of heat flow. This project aims to use selective laser melting to fabricate multi materials (316L stainless steel and Hovadur K220 copper) in two directions.
