An overview of three dimensional printing for casting applications

Rapid prototyping (RP) has been in evidence for the past 20 years and is being widely used in diverse areas, from the building of aesthetic and functional prototypes to the production of tools and moulds for technological prototypes. Among various RP techniques, three dimensional printing (3DP) is a relatively new form of RP. The present research paper provides an overview of RP process and specifically 3DP for shell patterns obtained from ceramic shells that can be built and then joined (as in the conventional process) to obtain the cavity for pouring metal for generation of cost effective prototypes for casting applications.
