Team Vision for Problem Definition Phase

During this phase, our team first set out to fully understand where the previous team, P16512, left off with the project. From there, we were able to understand the customer requirements which were still needed, and formulate engineering requirements to match. We also identified our key stakeholders, the risks associated with our project, and formulated a plan to move forward, among other things seen here.

Project Summary

Layered Manufacturing (LM) is a rapidly growing market with many opportunities for new advancement. The ink jet based LM printer needs to be capable of precisely placing ink drops to form an image using an ink formula which cures via ultraviolet light in a reasonable time frame to allow for the succeeding layer to be placed quickly. The printer should include monitoring systems for the critical parameters of the ink jet system. In finding the ideal ink formulation, additional metrics should be developed for assessing each formulas “jetability” and “curability”. A previous group working on this project was successful in developing independent X, Y and Z axis controls for moving the Reservoir Bucket, Jet Stack, Print Head Holder and Print Head, as well as an inexpensive UV curing system and a system for changing Reservoir Buckets. They also began work on a UV ventilation system.

The goal of this project is to continue and complete the solid start provided by the previous team to deliver a fully integrated prototype that is reliable, affordable, and user-friendly. The resulting device needs to meet the customer requirements for build size and resolution, and produce an image that can be built in a reasonable time with UV curing ink.

Project Goals and Key Deliverables

At the end of MSDII, the fixture should be capable of jetting and curing a 2 dimensional image at least, and needs to be made small enough to move to the AM print center where it will be used. If time and resources allow, there is a series of lower priority customer requirements

Constraints

The fixture needs to be small enough to fit in the elevator to go up to the AM print center, also the cables between the image loader and jet stack are a specific length, so the system needs to be designed around that.
