The purpose of this research is to design an illumination apparatus to project high quality images and cure them using Ultra violet beam. The developed apparatus is based on the concept of Projection based stereolithography in which a Digital Micromirror device (DMD) reflects image to cure the resin. In fields like bio engineering for example, the need for parts with high resolution and the existing manufacturing techniques do not match every requirement. To overcome this challenge and to achieve high speed fabrication, Bottom-up approach is used. The design for the developed experimental apparatus used to fabricate parts is discussed. The parameters are presented to achieve good quality prints are mentioned. Results of the print using Ultraviolet beam on the resin show the effectiveness of projection stereolithography. The possible constraints which may have an influence in the quality of the image are presented. This indicates that the developed model has the capability to print much more complex structures within minutes than the usual time consumed by other conventional methods. For the production of microstructures biocompatible photo curable material should be used.
