Final Project -Jarrett Dillenburger


The objective for our final project was to collaborate with a faculty or staff member in order to design and print a 3D object that could be used to promote a topic of interest. Since I am a strong supporter of chemistry research, I decided to collaborate with Dr. Annabel Edwards in order to develop a simple device that would be useful for the research conducted in the Edwards lab.

Currently, one of the research project in the Edwards lab relies heavily on the use of a Langmuir Trough (shown below). Along with  the ability to study the unique properties of molecules in monolayers (one molecule thick films), the instruments can also be used to transfer these monolayers using a Langmuir-Blodgett or Langmuir-Schaefer deposition technique. These techniques allow for the possible of creation of single and multi-layer films with precise control of thickness, molecular orientation and packing density.

Unfortunately,  the part required for Langmuir-Blodgett and Langmuir-Schaefer deposition (Labeled “5” below) is not available. I decided to create a less complex device via 3D printing to serve as a replacement for this more expensive device. The overall goal was to develop a device that could provide reproducible results since the current method involved using only steady hands.

The  device design underwent several iterative design prototypes before the final product was settle upon. The original design was planned to be much more complex that the final product. But, it was realized that the design did not need to be particularly complex to be effective at its function and so a simpler designs was chosen.
