Electrophotographic Cascade Development Apparatus ECDA Senior Design Project

Electrophotographic Cascade Development Apparatus ECDA - Senior Design Project P 15503 Team Members: Dalton Mead (ME), Bridget Kearney (EE), Zachary Foggetti (ME), Ruishi Shen (ISE), Thomas Wossner (ME) Background & Experimental Principle The purpose of the ECDA is to test a variety of charged particles for use in 3 D printing. The device was designed to improve upon an existing device used by RIT faculty. Charged particles flow down an inclined surface and pass between the charged plates, where they are attracted – “printed” – onto one of the plates. Customer & Sponsor Dr. Marcos Esterman, ISE Faculty Guide Sarah Brownell, Design, Development and Manufacturing Existing Device: Development zone plates not removable; transfer surface not smooth; particles cannot be collected after testing Mission – To design a device that • • Allows user to swap out the charged plate Allows different types of materials and flow rates Reduces materials lost throughout the test Reduces user waiting time to view the image Our Design: Aligns with our mission Key Concept Selections • Ensure smooth flow of particles? – Aluminum as the transfer surface! • Ease the process of viewing results? – Pillars with slots for the top plate! • Make the device easy to clean? – Clip slots to swap out the plates! Key Customer Requirements, Design Specs & Test Results Future Improvement Opportunities • Automate the adjustment of angle system • Add a recirculation system to iterate the tests • Integrate additional electrical system to control flow rate Special Thanks to: Mr. Edward Hanzlik (ME Faculty), Dr. Shu Chang (CIAS Faculty), Dr. Lynn Fuller (EE Faculty), Mr. George Slack (EE Faculty), and Mr. John Knapp
