Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Tested 3D prototype from manufacturer.
Figuring out how to insert four needles into cartridge since cannot be accomplished through 3D printing.
Finding ways to solve o-ring deformation assembly issue which can be possibly done with reverse action tweezers.
Explored ideas on how to seal current leakage.
Accomplishments from Previous Week
Tested 3D prototype and observed and listed high priorities that need to be solved.
Ordered necessary parts to resolve problems with current design.
Presented preliminary design review to instructor and class for more feedback.
Report and website were updated.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Seal space between storage tank and case.
Add 4 smaller holes by hand rather than having just one "large" hole.
Add more detailed simulations from ANSYS that displays further fluid analysis for both designs.
Finish final prototype.
Update report, team webpage, and begin final and poster presentation.
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Create a single handed use device
Mount a syringe into/onto the cartridge
Prepare a complete/workable CAD design based on our ideas and show to sponsors to figure out budget necessities.
Focus on optimizing previous team's design and fixing their prototype's flaws.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Discussion on how to attach cartridge to syringe and how to strap it to the pen.
Will need to ream the prototype since it is being done as a SLS print in order to smooth out the surface. Suggest SLA for next prototype.
Recommended to drill the four holes under a microscope for extra precision.
Will be receiving needles that can be used for cartridge.

N/A
Risks and Areas of Concern
Have not been able to meet with Dr. Duncan but consistently meetings with Dr. Dobke
Difficult to meet with everyone in person.
Do not have lab access so anything physical needs to be potentially done at home.
Current prototype:
Structure or materials of needles may deform/break during injection.
Optimize size of current cartridge
Agent delivery system does not work as a whole
Energy could impact conditions of the injected agent.
Resources or Information Required but not Available
Everything must be done virtually with the team.
Schedule
Describe upcoming milestone:
Test prototype
Refine/optimize design based on printed model
Draft poster
Edit/Work on report
Budget (list amount spent and amount remaining)
Obtained budget approval from Dr. Dobke to go ahead with necessary spendings
Have enough budget to outsource two prototypes
Progress on Report and Webpage
Report: edited and added more content for draft 2 of report
Webpage: updated internal, home, multimedia, and final design page
