Project Summary

Project Background:

Researchers in RIT’s PRISM lab would like to add to the set of materials available in today’s 3D printers. The purpose of this project is to develop a device that will test the electrostatic transfer properties of different types of granular materials and evaluate their suitability for use in a 3D printing device. This type of testing apparatus is called an Electrophotographic Cascade Development Apparatus (ECDA).

Problem Statement:

The customer would like to see a design that allows for a highly automated testing procedure. The ECDA must be capable of controlling particle flow rate, keeping particles contained within the apparatus, and utilizing a voltage differential to draw charged particles to a charged plate. It must also allow for easy viewing of test results and easy cleaning.
