This project is about application of indirect manufacturing an improved design of Polycrystalline Diamond Compact drill bit body by using Thermojet three dimensional printing and go through investment casting to become a final steel material. Three dimensional printing is also known as rapid prototyping is one of the convenient manufacturing technology since 1980’s. It was been promoted in the project due to its advantages and affection in society. The advantages and benefits such as less material required, enable to physicalize a complex structure product, time saving and high efficiency are really attractive to those creative innovator. Besides, within the technology development, the desired of manufacturing rate is keep rising and will be higher in future for sure. This situation make those traditional manufacturing methods harder and harder to keep track with the manufacturing rate required. In order to reverse the situation, rapid prototyping is one of the tool between the manufacturing rate and high precision product. The statement is agreed by the related research team and wish will fabricate a product to support the idea, and this is the reason of the project title. A computer aided design drawing has been modified from the previous model and divided into several parts to ease the three dimensional printing process. Every single divided part is separated within a reason to minimize the support structure and time consumed since the Thermojet printer will build up the model with an additive manner
