Abstract

A Capstone Project on Designing and Developing a Digital Light Processing 3D PrinterThis paper presents a capstone project on development of a low-cost 3D printer based onthe Digital Light Processing (DLP) technology. The work included in the paper is acontinuation of previous efforts at this engineering department in developing low-cost 3Dprinters and printing materials. An undergraduate student team consisting of mechanicaland manufacturing engineering students improved prior student project hardware andconducted a simple experiment studying impact of focus and exposure times with respectto print resolution in layer thickness. Before the experiments can be started, the team hadto rebuild the existing DLP hardware. The team followed the sequence of: planning andscheduling for the project, cleaning of the printer enclosure, application of the UV filteron the enclosure’s window, reverse engineering the previous printer design, purchasingand alteration of the new projector, studying the third party DLP software CreationWorkshop, research and procurement of DLP resins, designing and fabrication of a newresin container, designing and fabrication of a new build platform, and addition of a newcooling fan installation.End result of the project was a DLP printer that was operational and repeatable.Additional work is currently in progress to improve the accuracy of the parts made by theprinter through a Design of Industrial Experiments Study, involving a new group ofstudents and an industrial engineering faculty member. The objective is to reduce thelayer thickness and improve the support structure by utilizing industrial engineeringoptimization methods.In addition to the redesign and development process, the paper will present first-handexperiences of the student team throughout the project from the members’ accounts andwill conclude with the problems faced and resolved, safety measures and concerns, aswell as the ongoing work on the improvements.
