Rapid Prototyping(RP) techniques have revolutionized traditional manufacturing methods.
These techniques allow the user to fabricate a part directly from a conceptual model before
investing in production tooling and help develop new models with significant short time. This
paper suggests the new process to manufacture large size hollow shape parts for prototype-car
using Rapid Prototyping technology and Vacuum Molding with the reduction of delivery time. In
addition, this paper introduces the dividing and combining method to make large size RP master
model in spite of the limit of the build chamber dimensions of commercialized RP systems and
post-processing method to achieve sufficient surface quality.Mechanical Engineerin
