Team Vision for Problem Definition PhaseOur team planned to complete a few key deliverables during the problem definition phase. This includes conducting our customer interview, completing the required information for EDGE, and establishing a project plan and schedule for the remainder of MSD 1. Additionally, we went through team building activities inside and outside of class and started to accelerate through the forming phase.
We conducted our customer interview with Dr. Cormier and validated a lot of our initial assumptions on project requirements. We were able to reevaluate use scenarios and priority levels for customer requirements. It was a successful meeting and we look forward to future discussions with Dr. Cormier.
All of the required content for our EDGE site has been completed by the design review. Every team member contributed and no conflicts occurred. Customer and Engineering requirements, problem statement, use cases, and the design review presentation had team consensus and participation.
To summarize, we accomplished what we planned to do and are on track to have a successful semester.
Today’s industries are demanding lighter and stronger materials. Carbon, glass, and Kevlar fibers are promising to deliver these benefits, however, they are typically more expensive and time-consuming to produce than traditional materials. A 3D braiding machine could combat some of these issues by reducing manual labor. Continuous Fiber capable 3D printers already exist, however they are limited to planar application of carbon fiber. Other 3D Braiding machines exist, but are far too large and expensive for everyday use or do not integrate additive manufacturing.
The goal of this project is to design and develop a prototype braider which can weave fiber across three dimensions, which meets space, cost, function, ergonomic, and safety constraints specific to our customer. In future iterations, it will integrate with additive manufacturing to produce one cohesive part.

Project Goals and Key DeliverablesBy the end of the project, our customer can expect to have access to:
- 2-3 3D Braided samples with a 3D printed core
- Potential 3D Slicing/GCode software
- Documentation Regarding Scalability
- Working Prototype Braider
- Startup and Stop Documentation
- Design Documents
- Control Software (at least hard code for a select set of designs)
- Documentation of Prototype features, limitations, and suggestions for future revisions
- Maintenance Documents

Design Review Materials
- Pre-Read Document
- Action Items after the 1st review:
- Change ER19 to "portable" instead of "not too heavy [with weight limits]"
- ER12 - Establish proper metric for scalability
- Increase the importance of safety shielding
- Change binary safety ERs - potentially include OSHA standards
- Identify critical path forward
- Create vision statement and assign components to team members
- Improve risk management
