Team Vision for System-Level Design Phase
During this phase the team first brainstormed ideas for various aspects and functions of the simple 3D printing rig. These were added to a morphological chart (shown below). These ideas were then rated according to several selection criteria and the best concepts were selected. Using these filtered concepts a general idea for the systems level design was generated. All the data that was processed to ascertain this information is shown below.

Shown below is a fast diagram that shows all of the functions that the project will entail and how each function is linked to other functions in explicit detail. One can gain a decent overview of the project by studying this diagram.

Using this diagram the team began benchmarking several existing concepts to fulfill the functions shown above. The team also generated new concepts that could be used to fulfill these function as well.
Shown below is a picture of the Powerpoint presentation that the team constructed for benchmarking. This document contains all the most suitable existing methods to fulfill several functions in the project.

- Shown below is a morphological chart that was created by the team. All of the possible concepts that could be used to perform several of the functions required in this project or fulfill several of the aspects of this project are listed in the chart. Using this information, less desirable concepts were weeded out according to selection criteria.

This morphological chart needed to be constructed in order to develop the Pugh charts where the best possible or most suitable concepts were selected.
For each of the aspects of the system there were several concepts that the team came up with (See Morphological Chart). Each of these concepts were then ranked according to several selection criteria against a datum concept. The Pugh charts that the team developed for certain functions and aspects of the project are shown below.
- The Pugh Chart for Motion Direction is shown below:
- The Pugh Chart for the UV Curing System is shown below:
- The Pugh Chart for the Platen Material and the Securing System is shown below:
- The Pugh Chart for mounting the print head is shown below. This chart utilized a ranking system instead of the general point system:

Feasibility: Prototyping, Analysis, Simulation
The feasibility stage of this phase was performed to identify any potential issues that the team may encounter in the future. Plans, tests and measures were suggested by the team as to how these situations could be rectified and the best possible countermeasures were documented in the table shown below.
