The purpose of this study is to design and fabricate a doit-yourself (DIY) peristaltic pump and a flow cell for QCM biosensor. Outcomes of the design process involves, learning how to design 3D objects and how to adjust printing parameters in order to successfully fabricate a peristaltic pump and flow cell. Outcomes of the fabrication process involves learning how to transfer data to and from the embedded system controlling the pump and how to design a user interface running on the computer. The first phase of the project involved the design, where the 3D designing program was used to draw a 3D sketch of the parts; the second phase involved 3D printing and application of functional tests of flow rate and rotation speed. The final phase involved calibration of flow rate and pump parameters for tubings of various inner diameters.
