156B Week 9

Progress Report Week 9

Last week, our team CNC most of the components such as storage tank and the outer cover of the microneedling device. The building material is polycarbonate. This week the team will focus on the rest of the components such as the driving rod and silicon sealing layer. The driving rod will be 3D printed along with the luer lock and the fix holder. Also, the team will focus on the poster (and the preparation for presentation). 

Overview of the Status of Analysis, Design, Fabrication, Tests, etc.

• • The team fabricated the prototype of the 9 hollow needle pin with the storage tank.

 Accomplishments from Previous Weeks

• • The mold for the needles plate; CNC the outer cover and the storage tank.
