156B Week 10

MAE 156B. Group #8: Microneedling 

Team members: Mohammad Qubbaj, Yousif Bashalim Alomari, Jiaxin Huang, Xiaochen Song

Progress Report Week 10

Last week, the team finish assemble the microneedling prototype (except the hollow needles layer because the molding method is not working as the team expected). Some of the needles fail to attached or fixed in place by glueing. Therefore, the team CNC the hollow needles layer and attached the needles by glueing. 

The plan for this week is to finalize the poster and the report. At Tuesday, the team will meet with the doctors and present the final design.

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