Increasing of rapid prototyping performance by 3D printing technologies

Rapid prototyping (RP) is being recognised as a significant technology for future product development. One of the most effective RP technologies is 3D printing. A three dimensional object is created by layering and connecting successive cross sections of material. Therefore this new RP methodology is generally faster, more affordable and easier to use than any other additive fabrication technologies. This paper analyses performance of RP methods and compares these based on use-cases. Prototypes of casing type details have been created using different RP technologies. Productivity of product development process and 3D printing has been investigated. A problem in differences between physical prototypes compared to existing computer model (digital prototype) can be diminished by using comparative pre-testing. Case studies of increasing innovation capacity in development of casing type details have been analysed. In addition, suggestions for increasing innovation capacity and performance of rapid manufacturing have been made.
