About the Project

Project Time & Type:
Summer 2015 - DURI
Research area(s):
Mechanical Engienering, Manufacturing, Applied Physics
Project Description:
The ability to create 3D structures in the micro and nanoscale is important in many fields like electronics, microfluidics, tissue engineering and MEMS and is an emerging area of research. This project deals with the development and testing of a setup for building microscopic 3D structures with the help of a femtosecond laser. A method known as two photon polymerization is typically used to fabricate such structures in which a polymer is exposed to laser and at the point of the exposure the polymer changes its structure. Moving the laser in a predefined path helps in getting the desired shape and the structures are then built in a layer by layer fashion. The setup incorporates all the steps from a designing a CAD model file to slicing the model in layers to generating the motion path of the laser needed for fabricating the structure. In order to make a solid and stable structure, investigation of better materials and optimization of the process parameters is needed. Besides, possible improvements to the control algorithms used in the setup can be done to increase the efficiency of the process and build the structures faster.
Expected Student Contributions:
The intern will contribute to the development of the 3D laser printing process by participating in the experimental work including process planning using computer aided design - CAD tools, experiments execution, and data analysis.
