McMaster Series: 3D Manufacturing
1P13 Academic Project - Sterilization Container Design
Project Narrative
For those unfamiliar with McMaster's 1P13 project-based design, we follow a structured process with defined milestones. Upon completing these milestones, we submit our 'final deliverables' for completion.
Project Milestones
- Develop methods for safely transferring a container to an autoclave for sterilization
- Engineer a secure container for sterilizing surgical tools
- Develop a computer program to operate a robotic arm
- Validate and showcase the functionality and accuracy of your design
Final Deliverables
- A solid model of your proposed sterilization container design modelled in Autodesk Inventor and a 3D-printed prototype
- Develop a Python computer program
- Generate a comprehensive design project report documenting the entire project process

Team's Work and Personal Contributions
Timeline: Oct. 26th - Dec. 6th (2023)
Project 2 marked a significant progression within 1P13's course curriculum, where the cohort collectively experienced an accelerated pace. The overarching goal was to design a secure container for housing a designated medical instrument and implement code for the controlled transportation of the container to the sterilization device using a Q-Arm.
In my capacity as a key member of the Modelling sub-team and Team Co-ordinator, I played a pivotal role in contributing to the container's design process, ensuring alignment with specified requirements.
As the Co-ordinator, I ensured the success of the project in a timely manner. My primary contributions included keeping a concise record of calls, managing discussions, and meticulously maintaining meeting minutes.

Reflection
Throughout Project 2, the effective management of tasks and responsibilities became increasingly important. I reflected on "How can I assist in the submission of CAD files and major team documents?" This prompted a more refined approach, emphasizing timely contributions and the collaborative effort of the Modelling sub-team.
I also took an active role in designing the secure container, consistently asking, "How can we meet design constraints for weight, minimum space, and overall safety?" These self-guided questions shaped our design decisions.
Similar to the challenge of balancing creativity with realism in the previous project, I asked, "How can we address communication gaps between the computing and modelling sub-teams?" Recognizing this potential issue led to the proposal of post-Design Studio discussions to improve coordination.
