Development of Rapid Prototyping Technique using Sheet Metal and Projection Welding
Sang-Chan Lee, Jin-Ho Choi
Abstract
In today's highly competitive marketplace, it is of great significance for the manufacturing industry to reduce lead-time and costs for the product development. Since first emerged in 1986, Rapid Prototyping (RP) technology has helped successfully to reduce time and costs. Recently, RP using functional materials such as metal has been researched. However RP using the molten metal has been struggling to resolve several drawbacks, such as dimensional inaccuracy, poor surface finish, post finishing, etc., that originate primarily from the overall deposition of molten metal for each layer. So, the purpose of this study is to develop a new RP technique using sheet metal and projection welding for reducing several drawbacks in occurring RP using molten metal. Also tensile and bending specimens were made by the developed RP process using projection welding and were verified.
